Influence Of Calcination Temperature Research Articles

Effect of calcination temperature on structure evolution of hematite nanoparticles

The objective of this study is to investigate the transition structure of iron oxide, specifically the change from magnetite to hematite, as well as the influence of calcination temperature on the structural growth of hematite nanoparticles. The magnetite was extracted from the native iron sand in Indonesia using the coprecipitation procedure. To generate hematite, magnetite was calcined at various temperatures (350, 500, 650, and 800 °C). The structural changes resulting from the effect of calcination temperature were investigated by combining a number of characterisation methods. The crystal structure was examined using synchrotron x-ray diffraction (SRD) and the local structure was examined using x-ray absorption spectroscopy (XAS). Crystallite size was calculated using the Debye-Schrerrer equation at the most dominant SRD peak. Surface morphology was investigated using scanning electron microscopy (SEM). SRD data revealed that the sample calcined at 350 °C displayed both the Fe3O4 and α-Fe2O3 phases, while higher temperatures revealed the single-phase α-Fe2O3. Furthermore, an increase in calcination temperature was shown to be associated with an increase in crystallinity and crystallite size. For the samples H350 and H800, the crystallinity increased from 95.56 to 98.17%. In the magnetite, H350, H500, H650, and H800 samples, the crystallite size increased from 9.57 to 29.55, 16.40, 28,48, 29.26, and 29.55 nm. Higher calcination temperatures, on the other hand, increase the interatomic distance while decreasing the Debye–Waller factor, according to XAS fitting data. It can be inferred that around 500 °C, the transition from Fe3O4 to single-phase α-Fe2O3 was observed. While a greater calcination temperature of at least 800 °C would alter the structural parameters, it would not affect the phase.

In vitro immersion study and characterization of biomimetic bovine hydroxyapatite scaffolds: Influence of calcination temperature (600 and 1000 °C) on apatite formation

This work reports on the properties of natural bovine hydroxyapatite (HAp) scaffolds calcined at temperatures of 600 and 1000 °C and on the effects of apatite formation on these calcined scaffolds during immersion experiments in Hank's Balanced Salt Solution (HBSS) from 0 to 28 days. The study systematically identifies different mechanisms that determine the formation of the apatite layer. First, compositional analysis of the scaffolds by inductively couple plasma (ICP) reveals significant differences in macromineral content, which includes calcium, phosphorus, magnesium, and sodium. Subsequent X-ray diffraction (XRD) analysis reveals the presence of hydroxyapatite in both scaffolds, while the 1000 °C sample has additional β-whitlockite due to the higher calcination temperature. Further investigation by Fourier Transform Infrared Spectroscopy (FTIR) and Raman analyzes revealed carbonated HAp in the 600 °C scaffolds and characteristic bands of HAp in the 1000 °C scaffolds. Morphological changes during immersion, documented by Scanning Electron Microscopy (SEM) images, display leaf-like and cauliflower-like structures in the 600 °C sample and rash-like features leading to leaf-type apatite formation in the 1000 °C sample. High-Resolution Transmission Electron Microscopy (HR-TEM) showed elongated crystals in both samples, confirming exclusive HAp presence in the 600 °C sample and the coexistence of HAp and β-whitlockite phases in the 1000 °C sample. After 28 days of immersion, TEM images at 600 °C reveal ordered apatite particles, while the 1000 °C images exhibit random apatite formation, confirmed by Energy Dispersive X-ray Spectroscopy in TEM (EDS-TEM). In addition, both scaffolds calcined at 600 and 1000 °C showed biocompatibility, as cytotoxicity tests confirmed a remarkable 100 % cell viability, underlining their non-toxicity. The scaffolds calcined at 600 and 1000 °C therefore exhibit high bioactivity and viability, supporting their suitability for bone tissue engineering applications.

Effect of calcination temperature on structural, morphological elastic and electrical properties of MgO nanoparticles synthesized by combustion method

This study explores the influence of calcination temperature on the properties of MgO nanoparticles (MgO NPs) synthesized via the solution combustion method. Through X-ray diffraction (XRD) and scanning electron microscopy (SEM), structural and morphological changes were investigated. Elastic and dielectric properties were analyzed using computational tools and impedance spectroscopy. Results show that the prepared nanomaterial is belongs to a cubic system and a space group of F m −3 m. Increasing in the calcination temperature (550 °C and 750 °C) enhances crystallinity, reduces defects, and improves structural uniformity. Elastic properties exhibit notable improvements, with Young's modulus increasing from 356.43 GPa for pristine MgO to 364.6 GPa for MgO calcined at 750 °C. Dielectric studies were conducted in the frequency range from 50 to 5 MHz at room temperature. Dielectric analysis reveals enhanced properties, including increased dielectric constant and AC conductivity with rising temperature. The study emphasizes the pivotal role of calcination temperature in tailoring MgO NPs for diverse applications.

Optical and electrochemical properties of manganese oxide (Mn3O4) nanoparticles: Investigating the influence of calcination temperature on supercapacitor performance

In this study, we investigate the influence of calcination temperature on the structural, optical, and electrochemical properties of Mn3O4 nanoparticles synthesized through a chemical co-precipitation route. Field-Emission Scanning Electron Microscopy (FESEM) images depict the formation of highly agglomerated, spherical-shaped particles. At calcination temperatures of 700 °C and 900 °C, the observation reveals the emergence of flat pellets and rod-like structures. The X-ray Diffraction (XRD) patterns confirm the presence of the Mn3O4 phase in M0 and M1 samples. However, the sample calcined at 500 °C (M3) showed a mixed phase of Mn3O4 and Mn2O3. Upon further calcination at 700 and 900 °C, this mixed phase undergoes complete transformation into the Mn2O3 phase. The change in absorption onset and photoluminescence intensity of samples is found with an increase in calcination temperature due to the crystal growth and phase modification. Furthermore, the synthesized samples are employed as electrode materials for supercapacitor applications. The sample calcined at 300 °C (M1) in three-electrode system demonstrated the specific capacitance (Csp) of 273.3 F/g at 0.5 A/g in an alkaline medium. The asymmetric cell assembled by using M1 and Hibiscus cannabinus stem-derived carbon material (HBC-900) delivered higher Csp of 205.7 F/g at 0.5 A/g. In addition, asymmetric supercapacitor device exhibited a high energy and power density of 43.1 Wh/kg and 476.2 W/kg with 82.07 % of initial Csp retention over 10,000 cycles at 10 A/g, which makes the sample M1 as the potential electrode material for supercapacitor application.

Surface functionalized visible light-responsive yttrium orthovanadate for photocatalytic hydrogen production

Yttrium orthovanadate (YVO4), a wide-bandgap photocatalyst was tuned into a visible responsive material by anchoring an organic framework on the surface of YVO4 nanoparticles using polyethyleneimine (PEI). The surface organic framework was identified as the decomposed PEI derivatives with the carbonyl and carboxylic acid functional groups by the FTIR and XPS analyses. The top of the valence band (VB) was raised and the bottom of the conduction band was moved down; hence, the band gap of YVO4 was reduced to absorb the light in the visible region for all three synthesized samples, which was confirmed by DRS UV–Vis analysis. The functional groups facilitated more water molecules on the YVO4 surface via hydrogen bonding; hence, the YVO4 surface acquired superhydrophilicity. Among the three YI, YII, and YIII samples synthesized with three different calcination temperatures of 80, 260 and 400 °C respectively, YII showed many advantageous photocatalytic properties. The optimum loading of organic compounds obtained on YII surface at 260 °C, which improved the surface area, visible light absorption, hydrophilicity, and exciton's life. Hence, YII showed a better performance of 3.75 mmol h−1g−1cat H2 production than YI and YII. This work interestingly revealed the influence of calcination temperature on surface functionalization and the performance of catalytic materials.

Nanoscopic hygrometry: Exploiting porous nature zinc-doped tin oxide nanoparticles for enhanced humidity sensing at ambient temperature

This study focuses on zinc-doped tin oxide nanoparticles (Zn-SnO2 NPs) as promising humidity sensors. Through a chemical coprecipitation method, we synthesized Zn-SnO2 NPs and explored the influence of calcination temperature on their properties. X-ray diffraction confirmed the tetragonal rutile structure, and morphological analysis revealed a cauliflower-like morphology with enhanced porosity after calcination. UV-Visible absorption spectroscopy and photoluminescence measurements demonstrated a blue shift in the absorption peak and significant emission peaks related to oxygen vacancies, indicating improved humidity sensing potential as increasing the calcination temperature. The controlled calcination process led to successful outcomes, precisely tuning the NPs structure and optical behavior for enhanced humidity sensing capabilities. Conductivity studies have highlighted the semiconducting behavior of the NPs and observed that an increase in calcination temperature reduces their conductivity. Notably, humidity sensing experiments revealed a remarkable response of 93% and an exceptional response time of 30 seconds for the calcined NPs, surpassing the uncalcined sample. The sensing mechanism involving physisorption, chemisorption, and capillary condensation of water molecules on the NPs surface was validated. Moreover, the stability test over two month demonstrated consistent and highly stable humidity sensing response, reaffirming the NPs potential as effective and reliable humidity sensors.

Feasibility of Powder‐Based High‐Throughput Synthesis for Ceramics Development: Case Study on the Influence of Calcination Temperature in BiFeO3‐BaTiO3

Recent advances in machine learning capabilities have increased interest in materials research to improve the efficiency of materials discovery and optimization as well as to better understand the underlying phenomena responsible for the observed physical properties. While combinatorial chemistry and compositional engineering is well established in the development of pharmaceutical and chemical products, its use in the field of bulk functional polycrystalline ceramics is far from mature. In this work, a critical review of a high‐throughput powder‐based dispensing system is provided and the challenges involved with the transition from a conventional, human resources intensive workflow to a fully automated process are highlighted. Based on the lead‐free piezoelectric BiFeO3–BaTiO3 binary system, the applicability and robustness of high‐throughput engineering is investigated to increase data point density in phase diagrams, including the composition variations of the resulting materials. This work presents 16 different BiFeO3–BaTiO3 compositions at four different calcination temperatures, both demonstrating the potential of the system. This is coupled to automated crystal structure analysis, which will be used to investigate the role of calcination temperature on the resulting compositions at room temperature.

Influence of calcination temperature on the physical and chemical characteristics of kaolinitic clays for use as supplementary cementitious materials

Clays have the potential of being the most important supplementary cementitious material for the future. The quality of calcination, which has a very important influence on the suitability of clay as a partial replacement of cement, is influenced by the changes in the characteristics of clays during calcination. An improved knowledge of these changes can help to assess the suitability of clays. In this study, clays were calcined at seven temperatures ranging from 400 °C to 1000 °C and the effect of calcination temperature on physico-chemical properties like specific gravity, specific surface area, water demand, morphology and reactivity were investigated. The results showed that the transformation process of kaolinite to metakaolin, which is the main reactive phase in cements, completes by 800 °C and this conversion process governs the reactivity, without changing the physical properties. The metakaolin becomes unstable at calcination temperature of 1000 °C, and transforms into the spinel phase as confirmed by the differential scanning calorimetry. The spinel phase reduces the reactivity and also changes the physical properties of calcined clays, making the calcined clay unsuitable for use in cements. New test methods that can be employed to rapidly assess the quality of calcination are also discussed.

Phase formation, microstructural and dielectric properties of bismuth ferrite nanoceramics synthesized by low-temperature molten salt flux route

BiFeO3 nano-ceramics were synthesized using the low-temperature molten salt synthesis route to study the influence of calcination temperature and salt ratios. The Rietveld refinement revealed the distorted perovskite structure of BFO. These granular-shaped BFO samples’ grains morphology was studied using the FESEM. The FTIR revealed the presence of Metal-Oxygen bonds in the BFO ceramics. The XPS studies exhibited the respective constituent elements’ oxidation states and validated the presence of oxygen ion vacancies. The frequency-dependent dielectric properties were measured at various temperatures. The electrical conductivity measurement showed a linear variation as a function of frequency which validated Jonscher’s power law.

Structural and antibacterial properties of copper oxide nanoparticles: a study on the effect of calcination temperature

Nanoparticles of copper oxide were synthesized by the simple precipitation method. The influence of calcination temperature on the structural characteristics and antibacterial activity of the nanoparticles were evaluated. The nanoparticles were analyzed by Bruner-Emmett-Teller (BET) surface area and pore size analyzer, x-ray diffraction, transmission electron microscope and scanning electron microscope. The findings demonstrated the formation of copper oxide nanoparticles showing a monoclinic phase. Before calcination, the nanoparticles showed a high BET surface area with rod shape morphology and size range between 18–70 nm and after calcination, irregular spherical-like morphology with size range of 20–200 nm was observed. However, it was evident that the BET surface area decreased gradually with increasing calcination temperature, while the nanoparticle size increased forming an irregular spherical shape. Subsequently, the copper oxide nanoparticles demonstrated that they are highly effective for bacteria inactivation. The inactivation activity was found to be more effective with uncalcined nanoparticles than with calcined nanoparticles. This was due to the large nanoparticle sizes and the decrease in surface area obtained after calcination. Thus, it was noted that calcination of the as-prepared nanoparticles significantly affects the structural and antibacterial properties. Hence, for antibacterial application, calcination was not necessary as the nanoparticles showed excellent antibacterial results.

Combination of ensemble machine learning models in photocatalytic studies using nano TiO2 - Lignin based biochar

Synergizing photocatalytic reactions with machine learning methods can effectively optimize and automate the remediation of pollutants. In this work, commercial Degussa TiO2 nanoparticles and lignin based biochar (LB) where used to prepare TiO2: lignin based biochar (TLB) composites using ultrasound-assisted co-precipitation method. The photocatalytic property of the TLB composites where studied by conducting the photocatalytic degradation of a Basic blue 41 (BB41) dye. The influence of calcination temperature, T:LB compositions, catalyst dosage, initial dye pH, initial dye concentration, and illumination time on photocatalytic dye degradation were experimentally studied. The degradation efficiency of 96.72 % was obtained under optimized conditions for the photocatalyst calcined at 500 °C containing a 1:1 wt percentage of TiO2 and LB. The experimental data was further used to predict the photocatalytic degradation efficiency using Gradient Tree Boosting (GTB) and Extra Trees (ET) models. The GTB model gave the highest prediction accuracy of 94 %. The permutation variable importance revealed catalyst dosage and dye concentration as the most influential parameters in the prediction of the photocatalytic dye degradation efficiency.

Research on the Influence of Calcination Temperature on the Content of Free Silicon Dioxide in Dust

In order to verify the oxidation of silicon to silicon dioxide during the calcination process of silica containing dust, silicon powder and monocrystalline silicon were calcined at different temperatures. The sample was analyzed using Fourier transform infrared spectroscopy (FTIR) and compared with the FTIR spectrum of the silica standard. The results show that the antisymmetrical stretching vibration, symmetrical stretching vibration and bending vibration absorption peak of Si-O-Si were obviously in the FTIR spectra of silicon powder and monocrystalline silicon calcined at 750oC. The positions of those absorption peaks correlate broadly with the absorption peaks of standard silica. It is concluded that when the calcination temperature was above 750oC, elemental silicon would be oxidized to silica at different levels, which would cause a higher silica content detected in dust.

Degradation of tannic acid using monopersulfate activated CuO particles

A Copper(II) oxide material was synthesized and its efficiency in degrading Tannic acid (TA) was investigated using ultraviolet (UV) irradiation and CuO activated peroxymonosulfate (PMS). The CuO particle catalyst exhibited exceptional activity and was characterized using XRD, SEM, Raman spectroscopy, and laser diffraction particle size analysis (LDPS). The influence of calcination temperature, UV power, PMS dosage, CuO dosage, and coexisting anions on the degradation rate of TA was examined. The research results demonstrate that the addition of a structural guide enhances the catalytic performance of CuO. Among the different calcination temperatures investigated, CuO calcined at 500 °C demonstrates the best catalytic performance and achieves the highest degradation efficiency under neutral conditions. Under the optimal conditions of 0.1 g/L CuO and 1.2 mmol/L PMS, the TA degradation rate of 15 mg/L within 40 min was 97.69%, and the total organic carbon removal rate was 69.85%. Quenching experiments confirmed the participation of multiple active species in the decomposition process. After five experimental cycles, the CuO material maintained a TA removal rate above 92%. Furthermore, HPLC-MS analysis was employed to identify potential intermediates in the degradation of TA.

Effect of calcination temperature induced structural modifications on the photocatalytic efficacy of Fe2O3-ZrO2 nanostructures: mechanochemical synthesis.

Water contamination due to organic pollutants is a challenging issue around the globe, and several attempts have been made to deal with this issue. Out of which, the semiconductor-based photocatalytic process had gained much attention and proved to be an efficient, easy, and economical process for the removal of organic dyes from aqueous solutions. For this purpose, the iron oxide-zirconium dioxide nanocomposite (Fe2O3-ZrO2 NC) was prepared via a simple mechanochemical process using a mortar and pestle, followed by a calcination process at 300, 600, and 900 °C. Different physicochemical analyses were carried out in order to investigate the successful synthesis of Fe2O3-ZrO2 NC and the effect of temperature on the crystallinity, surface area, pore size, phase composition, sample morphology, and particle/crystallite size. The Fe2O3-ZrO2 NCs were subjected to a photocatalytic test under solar light irradiation against fluorescein dye in an aqueous medium, and the photocatalytic performance was examined under the influence of calcination temperatures, pH, catalyst dose, and initial concentration. The stability of the Fe2O3-ZrO2 NCs was also checked by recycling them for five reuse cycles.

Removal of direct blue FFRL by layered double hydroxides: Thermodynamics and kinetics

In this paper, MgAl layered double hydroxides (LDH) with molar ratio of nMg:nAl = 2:1 was successfully synthesized by conventional co-precipitation method to remove direct blue FFRL (FFRL). In order to study the influence of calcined temperature to FFRL removal, a series of calcined layered double hydroxides (CLDH) samples was obtained by calcination at 200, 450, 600, 800 °C for 6 h, respectively. BET, XRD and SEM were used to analyze the structure of MgAl-CLDH calcined at different temperature. The MgAl-CLDH calcined at 450 °C exhibits the most considerable removal efficiency, which is corresponding to the results of BET. The equilibrium isotherm of FFRL removal by MgAl-CLDH can be better described by Langmuir model. The process of FFRL removal by MgAl-CLDH is spontaneous and exothermic with an increasing in molecular order. Removal of FFRL by MgAl-CLDH also conforms to the pseudo-first-order model with activating energy of 129.6 kJ/mol, which proves that the removal of FFRL by MgAl-CLDH is controlled by a chemical reaction between FFRL and MgAl-CLDH.

Influence of calcination temperature on the morphology, structure, and spectral performance of chromium oxide

Cr(OH)3 was synthesized by a hydrothermal method using Na2Cr2O7 as precursor and starch as reducing agent. The resulting Cr(OH)3 was then calcined at different temperatures to produce Cr2O3 pigments. X-ray diffraction (XRD), X-ray photoelectron Spectrometer (XPS), UV–Vis-NIR spectroscopy, scanning electron microscopy (SEM) and automated whiteness measurement (AWM) were used to characterize the crystalline phase, reflectivity, morphology and color of Cr2O3. At temperatures below 1000 °C, Cr2O3 was identified as the dominant phase during calcination. The results showed that when the calcination temperature was <1000 °C, the phase was identified as Cr2O3. When the calcination temperature was ≥1000 °C, some oxygen atoms (O) escaped from the Cr2O3 crystal structure to from Cr2O2.4, and a shift of the Cr2O3 diffraction peak to a higher angle was observed. XPS analysis revealed that the valence state of O in the samples subjected to calcination at both 700 °C and 1200 °C remained unchanged. However, the sample treated at 1200 °C displayed a distinct CrOx (X < 1.5) peak at 575.25 eV, indicating a lower oxidation state of Cr. Morphologically, a conversion from particle-shaped Cr2O3 to larger plate-like Cr2O2.4 structures was observed, with Cr2O3 being concentrated on the Cr2O2.4. The uneven distribution of crystal particles in chromium oxide samples led to an increase in reflectance and a decrease in brightness as a result of the presence of Cr2O3 and Cr2O2.4 with distinct structural forms.

Zn-Zr induced structural and magnetic changes in strontium hexaferrite system

Polycrystalline samples of M-type Strontium hexaferrite having chemical composition SrZnxZrxFe12–2xO19 (with x = 0 and 1 and abbreviated as SFO and SZFO, respectively) were prepared successfully using solid state reaction route. The influence of calcination temperature (900 °C – 1300 °C) on the structural, microstructural, and magnetic properties of the SFO samples was explored. X-ray analysis reveals that the SFO sample is pure over the whole calcination range. The obtained X2 (goodness-of-fit; GoF) values are in the ≈ 1.02 - 1.16 range. At 1300 °C, the SFO sample develops preferred orientations along (006), (008) and (0014) crystallographic planes. The incorporation of preferred orientations leads to an improvement in the value of GoF from ≈ 4.72 to ≈ 1.16 (at 1200 °C). However, no preferred orientations are observed in the SZFO samples. Single phase Rietveld refinement is insufficient to explain the structural data. A four - phase and a three -phase refinement has been observed to be suitable in samples calcined at 1200 °C and 1300 °C, respectively. FESEM micrographs reveal a dramatic change in grain size and shape at 1300 °C in both types of samples. The best of magnetic properties has been observed at 1200 °C calcination in both types of samples. The best Mr, Ms and Hc values have been observed45.36, emu/g, 90.26 emu/g, 5032 Oe (in SFO sample) and 10.39 emu/g, 58.22 emu/g and 1181 Oe (in SZFO sample), respectively. The lower magnetic parameter values of SZFO samples can be attributed to magnetic dilution. Low temperature M-T measurements establishes the absence of magnetic nature of segregated phases in x = 1 sample.

Effect of Calcination Temperature on the Powder of Freshwater Snail Shells (Sulcospira testudinaria) Properties

Gastropod shells, such as those from the freshwater snail (Sulcospira testudinaria), have garnered interest as potential sources of calcium precursors. These shells are rich in calcium carbonate (CaCO3), which can be thermally decomposed into calcium oxide (CaO) through calcination. However, more information is needed on optimizing calcium extraction from the Sulcospira testudinaria (SST) shells. This study aims to investigate the influence of calcination temperature on the characteristics of powder of these shells. The study involves two sample treatments: uncalcined shells and shells calcined at temperatures ranging from 500°C to 1100°C for 1 hour. Fourier transform infrared spectroscopy (FTIR) analysis of uncalcined shell powder revealed the presence of aragonite functional groups within the CaCO3 structure. X-ray diffraction (XRD) analysis provided insights into the transformation of crystalline phases of CaCO3, starting from aragonite to calcite and eventually to calcium oxide, explaining the material's weight loss during calcination. The conversion of aragonite to calcite occurs between 500°C and 700°C, while optimal decomposition into CaO is achieved at 1000°C. X-ray fluorescence (XRF) analysis indicated reduced impurities in the samples post-calcination. Scanning electron microscopy (SEM) detailed the morphological characteristics of the shell powders, highlighting temperature-dependent surface features. In conclusion, the optimal calcination temperature for extracting calcium from SST shells is 1000°C. The resulting calcium oxide can be a valuable precursor for various material applications. This research contributes to the efficient utilization of biowaste resources, emphasizing the potential of freshwater snail shells in the sustainable production of calcium-derived materials.

Fabrication of fine-grained and high thermal properties Y2O3 transparent ceramics without sintering aids

Infrared transparent pure Y2O3 nanoceramics were fabricated from citric acid sol-gel combustion synthesized nanopowder and through the combination of hot pressing and hot isostatic pressing. The influence of calcination temperature on the morphology, particle size and agglomeration state of the nanopowders during powder synthesis process was investigated. Powder with a particle size of 15.5 nm and agglomeration factor of 3.3 was obtained with the calcination temperature at 700 °C for 4 h. Green compact with homogenous microstructure and improved sintering activity was consolidated by cold isostatic pressing after dry pressing. Y2O3 transparent ceramic was achieved with hot pre-sintering at 1400 °C without holding plus hot isostatic pressing at 1450 °C for 2 h under 200 MPa pressure. As a result, the ceramic prepared with 1.0 mm thickness got the transmission of 80.4 %–83.9 % at 2.5 μm–6.0 μm wavelength with an average grain size of 413 nm. The sample's thermal conductivity was 12.84 W m−1 K−1 and the phonon energy was 592 cm−1, making it a promising material for IR transparent windows and host material for efficient infrared solid-state laser. The sintering mechanism was proposed and discussed.

Tailoring self-pulverized low-calcium clinker for CO2 sequestration

To reduce energy consumption and greenhouse gas emissions in the cement industry, this study develops a novel low-calcium clinker with self-pulverization properties. The clinker is synthesized from limestone and sandstone raw materials and comprises dicalcium silicate (2CaO·SiO2 (C2S)) as the primary mineral and rankinite (3CaO·2SiO2 (C3S2)) as the auxiliary mineral. The influence of calcination temperature, cooling rate, and holding time on clinker pulverization and mineral formation is investigated through a series of experiments. The optimal calcination condition involves heating at 1240 °C for 1 h, followed by natural cooling, resulting in a self-pulverized low-calcium clinker (SPLCC) with main mineral is γ-C2S and contains β-C2S, C3S2, and C2AS (Calcium alumina feldspar (2CaO·Al2O3·SiO2)). The self-pulverized clinker exhibits a pulverization ratio of 93.0 %, a specific surface area of 666.4 m2/kg, and an average particle size of 8.2 μm. Additionally, the clinker displays excellent carbonation reactivity, with the compressive strength reaching 69.3 MPa and 82.2 MPa after 4 h and 24 h of CO2 curing, respectively. The carbonation products are identified as calcite and silica gel. SPLCC can reduce and sequester approximately 277.3 kg of CO2 emissions compared to the hydration of Portland cement clinker when considering the preparation and curing stages. The results highlight the potential of SPLCC as a sustainable cementitious material.
