Borophosphate glass based electrolyte composite for high lithium ionic conductivity

The application requirements of solid-state lithium (Li) metal batteries are satisfied by the ionic conductivity of composite solid-state electrolytes, attributed to their minimal interfacial resistance. Herein, composite solid electrolytes were obtained by mixing a crystalline Li0.5La0.5TiO3 (LLTO) perovskite with different amount of 47Li2O-30B2O3-23P2O5 (LBP) glass phase. The results show that the crystal phase of the composite samples exhibit a tetragonal perovskite structure with a P4/mmm space group. Frequency dependent AC conductivity shows that composite containing 1 % LBP glass avoids the phenomenon of charge carrier blocking at low frequency and low temperature at the same time. The room temperature maximum total ionic conductivity was obtained for sample with 0.5 % LBP glass presenting a conductivity that is almost three times higher than that of pure LLTO. The factors influencing ionic conductivity are not only grain morphology and size, and activation energy, but also lithium content, and entropic effects contribute to the facility or difficulty with which Li+ can migrate into the LLTO solid electrolyte.

Rapid fabrication of Ba1–xSrxTiO3 ceramics via reactive flash sintering

Ba1–xSrxTiO3 (BST) ceramics are promising dielectric materials. However, their fabrication is usually laborious, requiring long preparation stages and high temperatures, which are not favorable for tuning the grain size and dielectric properties. In this study, (Ba1–xSrx)TiO3 (x = 0.1, 0.3, 0.5) ceramics were produced via reactive flash sintering (RFS) of a mixture of BaCO3, SrCO3 and TiO2 powders at 900 °C and relatively short times (15–90 s). The electric field (E-field) with a strength of 400 V/cm and the current densities of 25–75 mA mm−2 were applied during RFS. Once the Sr2+ content increased, the incubation time for the RFS decreased, suggesting that the addition of Sr2+ facilitated the RFS process. At the RFS time above 15 s, a single-phase Ba0.6Sr0.4TiO3 perovskite structure was formed. When the time and the applied current density increased, both the densities and grain sizes within the ceramics increased. This increased the real part (ε’) of the complex permittivity compared to that of the conventionally sintered (CS) ceramic. Moreover, the enhancement of mass transport by E-field-induced oxygen vacancies was considered the predominant mechanism of RFS in the production of BST ceramics.

Enhanced low‐field energy storage performance in Nd3+‐doped (Bi0.40K0.2Na0.2Sr0.2)TiO3 high‐entropy ceramics

AbstractThe burgeoning requirement for compact electronic devices has intensified research into lead‐free dielectric ceramics that offer superior recoverable energy storage density and efficiency at low electric fields. In this study, we report the synthesis of Nd3+‐doped (Bi0.4K0.2Na0.2Sr0.2)TiO3 perovskite ceramics via the solid‐state reaction technique. The synthesized ceramics adopted a tetragonal crystal structure. As the concentration of Nd3+ ions increased, both the maximum dielectric constant (εm) and its corresponding temperature (Tm) decrease. The incorporation of Nd3+ ions perturbed the long‐range ferroelectric order, leading to diminished maximum polarization (Pm) and remanent polarization (Pr). The ceramics achieved optimal properties with 12 mol% Nd3+ doping, showcasing a significant recoverable energy storage density of 1.50 J/cm3 at a low electric field of 140 kV/cm, along with an exceptional storage efficiency of 94.6%. This research not only highlights a promising candidate for dielectric materials in low electric field applications but also introduces an innovative approach to enhance energy storage performance.

Opportunity of ferrimagnetic (CZLF)/ferroelectric (BZT) composite materials in high frequency applications

The ferrimagnetic Zn0.35Co0.65 La0.02Fe1.98O4 (CZLF) ferrite with cubic spinel structure (space group Fd3m) was made into composite by mixing with ferroelectric Ba0.5Zr0.5TiO3 (BZT) perovskite with tetragonal structure (space group P4mm) at the mass ratio. Disk-shaped composite powder was finally heated at 1100 °C to study the structure, dielectric and ferroelectric properties. The structural characterization for synthesized samples were carried out using Fourier transform infrared and Transmission Electron Microscopy. Fourier transform infrared show the successful formation of composite samples which is also observed from x-ray diffraction pattern. In compared to their ferrite counterparts before the composite, dielectric response and ferroelectric characteristics of the composite samples are noticeably altered. Compared to the ferrite samples, the composite system exhibits a higher permittivity. In composite samples, the space charge polarization, which was primarily effective at low frequencies and high measurement temperatures, is much diminished. The mechanical properties and indentation creep of these bearing alloys were studied by Vickers indentation testing at room temperature. The remnant polarization of BZT/CZLF increases with decreasing BZT content, which may be suitable for permanent memory device applications. Graphical abstract

Titanate-based high-entropy perovskite oxides relaxor ferroelectrics

Different combinations of monovalent and trivalent A-cations in high-entropy perovskite oxides (HEPOs) were investigated. The multicomponent (A′0.2A″0.2Ba0.2Sr0.2Ca0.2)TiO3 (A′ = Na+, K+, A″ = Bi3+, La3+) perovskite compounds were successfully synthesized by solid-state reaction method persisting average cubic perovskite phase. The trivalent cation exhibited distinct effects on local structure, dielectric properties and relaxor ferroelectric behavior. Highly dense ceramics (> 95%), high dielectric constant (~ 3000), low dielectric loss (~ 0.1), and relaxor ferroelectric characteristics were obtained in the compound containing Bi3+. The La3+ containing compounds revealed lower dielectric constant, higher dielectric loss and linear dielectric behavior. The effect of monovalent cation on the dielectric properties was minimal. However, it affected relaxor ferroelectric behavior at elevated temperatures and conduction behavior at high temperatures. The (K0.2Bi0.2Ba0.2Sr0.2Ca0.2)TiO3 ceramic maintained the relaxor ferroelectric behavior with low PREM at high temperatures suggesting more stable relaxor ferroelectric characteristics than that of the (Na0.2Bi0.2Ba0.2Sr0.2Ca0.2)TiO3. Moreover, between these two compounds, the homogeneous electrical characteristics could be obtained from the compound consisting of K + and Bi + at A-site. This study suggests that tuning the chemical composition, particularly choosing appropriate combination of mono/trivalent cations in high entropy perovskite oxides, could be the effective approach to develop high-performance relaxor ferroelectrics with the desired properties.

Structure and equation of state of Ti-bearing davemaoite: new insights into the chemical heterogeneity in the lower mantle

Abstract Davemaoite (CaSiO3 perovskite) is considered the third most abundant phase in the pyrolytic lower mantle and the second most abundant phase in the subducted mid-ocean ridge basalt (MORB). During the partial melting of the pyrolytic upper mantle, incompatible titanium (Ti) becomes enriched in the basaltic magma, forming Ti-rich MORB. Davemaoite is considered an important Ti-bearing mineral in subducted slabs by forming a Ca(Si,Ti)O3 solid solution. However, the crystal structure and compressibility of Ca(Si,Ti)O3 perovskite solid solution at relevant pressure and temperature conditions were not systematically investigated. In this study, we investigated the structure and equations of state of Ca(Si0.83Ti0.17)O3 and Ca(Si0.75Ti0.25)O3 perovskites at room temperature up to 82 GPa and 64 GPa, respectively, by synchrotron X-ray diffraction (XRD). We found that both Ca(Si0.83Ti0.17)O3 and Ca(Si0.75Ti0.25)O3 perovskites have a tetragonal structure up to the maximum pressures investigated. Based on the observed data and compared to pure CaSiO3 davemaoite, both Ca(Si0.83Ti0.17)O3 and Ca(Si0.75Ti0.25)O3 perovskites are expected to be less dense up to the core-mantle boundary (CMB), and specifically ~1-2 % less dense than CaSiO3 davemaoite in the pressure range of the transition zone (15-25 GPa). Our results suggest that the presence of Ti-bearing davemaoite phases may result in a reduction in the average density of the subducting slabs, which in turn promotes their stagnation in the lower mantle. The presence of low-density Ti-bearing davemaoite phases and subduction of MORB in the lower mantle may also explain the seismic heterogeneity in the lower mantle, such as large low shear velocity provinces (LLSVPs).

Zero-Strain Sodium Lanthanum Titanate Perovskite Embedded in Flexible Carbon Fibers as a Long-Span Anode for Lithium-Ion Batteries.

"High-capacity" graphite and "zero-strain" spinel Li4Ti5O12 (LTO) occupy the majority market of anode materials for Li+ storage in commercial applications. Nevertheless, their intrinsic drawbacks including the unsafe potential of graphite and unsatisfactory capacity of LTO limit the further development of lithium-ion batteries (LIBs), which is unable to satisfy the ever-increasing demands. Here, a novel Na0.35La0.55TiO3 perovskite embedded in multichannel carbon fibers (NLTO-NF) is rationally designed and synthesized through an electrospinning method. It not only has the advantages of a respectable specific capacity of 265 mAh g-1 at 0.1 A g-1 and superb rate capability, but it also possesses the zero-strain characteristic. Impressively, an ultralong cycling life with 96.3% capacity retention after 9000 cycles at 2 A g-1 is achieved in the half cell, and 90.3% of capacity retention ratio is obtained after even 2500 cycles at 1 A g-1 in the coupled LiFePO4/NLTO-NF full cell. This study introduces a new member with excellent performance to the zero-strain materials family for next-generation LIBs.

This work reports the use of lead-free Na0.5Bi0.5TiO3 perovskite as a lithium-ion battery anode and explores its charge storage mechanism. It opens the door to explore numerous Bi-based oxides capable of reversibly hosting lithium.

Oxide-Halide Perovskite Composites for Simultaneous Recycling of Lead Zirconate Titanate Piezoceramics and Methylammonium Lead Iodide Solar Cells.

Global concerns over energy availability and the environment impose an urgent requirement for sustainable manufacturing, usage, and disposal of electronic components. Piezoelectric and photovoltaic components are being extensively used. They contain the hazardous element, Pb (e.g., in widely used and researched Pb(Zr,Ti)O3 and halide perovskites), but they are not being properly recycled or reused. This work demonstrates the fabrication of upside-down composite sensor materials using crushed ceramic particles recycled from broken piezoceramics, polycrystalline halide perovskite powder collected from waste dye-sensitized solar cells, and crystal particles of a Cd-based perovskite composition, C6H5N(CH3)3CdBr3 xCl3(1- x ). The piezoceramic and halide perovskite particles are used as filler and binder, respectively, to show a proof of concept for the chemical and microstructural compatibility between the oxide and halide perovskite compounds while being recycled simultaneously. Production of the recycled and reusable materials requires only a marginal energy budget while achieving a very high material densification of >92%, as well as a 40% higher piezoelectric voltage coefficient, i.e., better sensing capability, than the pristine piezoceramics. This work thus offers an energy- and environmentally friendly approach to the recycling of hazardous elements as well as giving a second life to waste piezoelectric and photovoltaic components.

Atomic‐scale insights into electronic, structural, dielectric, and ferroelectric properties of Ba(Zr, Ti)O3 perovskites

Ba(Zr, Ti)O3 perovskites are promising lead-free piezoelectric and relaxor ferroelectric materials for energy storage and harvest devices, of which the ferroelectric mechanism has long been ambiguous. We theoretically investigated the ferroelectric mechanism from the electronic and atomic scale using first-principles calculation based on density functional theory and density functional perturbation theory. With increasing zirconium content, it is obtained a lattice expansion and a decrease in the ferroelectric polarization in agreement with experiment. An unstable zone-center phonon mode is observed in the polar ferroelectric phase, which tends to stabilizein the nonpolar paraelectric phase, which is associated with the engineering of the relative displacement of the B-site ions that alters the short-range force. The newly formed Ti/Zr (dzx,dyz)-O (2px,2py) π-type bonds are discovered to be the origin of the Ba(Zr, Ti)O3ferroelectric instability and polarization. Local relaxation strains caused by lattice misalignment of the ionic displacements of Ti ions and Zr ions suppress the polarization of Ba(Zr, Ti)O3 by counteracting the off-centering of Ti ions and adjacent Zr ions in certain directions.

Self-regulated interfacial-enhanced piezo-phototronic effect of BNT@Mn-SnO2 heterostructures for superlative tetracycline degradation

The piezo-promoted photocatalysis has recently been evolved as an auspicious technique to achieve high-efficiency and scalable organic pollutant degradation. Herein, a visible light active heterocomposite BNT@Mn-SnO2 (BSM) with plate-like Bi0.5Na0.5TiO3 (BNT) perovskite and Mn Nps decorated SnO2 was synthesized for the piezo-photocatalytic degradation of Tetracycline (TC). The piezo-photocatalytic degradation efficiency of TC reached 95.4% in 60 min, and the rate constant k reaches 0.078 min−1 which is 13 times and 2.8 times higher than the piezocatalytic and photocatalytic k values, individually. The meticulous built-in electric field regulation of BNT modified the band-gap structure and induced efficient charge separation in BSM nanocomposite. Furthermore, the plasmonic effect of the Mn Nps tuned the band-edge positions of SnO2 by introducing impurity energy levels and provided an alternative source of charge storage, and amplified the light absorption range of BSM nanocomposite. The oxidative species, particularly OH• played a substantial role in the piezo-photodegradation process than O2•- and 1O2. Besides, the toxicity evaluation revealed that the self-regulated interfacial-enhanced piezo-phototronic effect of BSM nanocomposite can deliberately reduce the ecotoxicity level into smaller and non-toxic compounds. This work provides a novel strategy to design efficient and sustainable piezo-photocatalysts for environmental remediation.

Prediction of lattice distortion and mechanical behavior of tetragonal phase (Bi0.2Na0.2Ba0.2Sr0.2Ca0.2)TiO3 high-entropy perovskite with A-site disorder from first-principles calculations

High-entropy perovskite ceramics have drawn widespread attention as their excellent physical properties. Herein, the high-entropy (Bi0.2Na0.2Ba0.2Sr0.2Ca0.2)TiO3 (BNBSCT) perovskite is selected as case study. The distorted structure and mechanical behavior as well as the effect of pressure are comprehensively studied through implementing first-principles calculations in conjunction with special quasi-random structure. The results reveal the atomic random distribution and size different cause serious lattice distortion within the BNBSCT structure, and the pseudo-intralayer distortion is significantly smaller than the interlayer distortion. Further studies of the mechanical properties indicate that the high-entropy BNBSCT perovskite is mechanical stable, especially larger elastic parameters imply the larger resistance against elastic deformation in comparison with Bi0.5Na0.5TiO3. Compared to the rule of mixture, the higher resistance to volume deformation and crack propagation of BNBSCT suggests the strengthening of high-entropy perovskite presumably due to lattice distortion in structure. Increasing pressure leads to decrease in lattice parameter and volume of structure, then increases the degree of lattice distortion, elastic constants and elastic moduli, as well the degree of lattice distortion. Moreover, the ductility and fracture toughness are also enhanced, though the elastic anisotropy is slightly larger. This work provides a new insight into the high-entropy perovskite under high pressure, which will contribute to the further research and application of high-entropy materials.

Comparison of Photocatalytic Performance of Sr0.9La0.1TiO3 and Sr0.25Ca0.25Na0.25Pr0.25TiO3 Towards Metoprolol and Pindolol Photodegradation

The photocatalytic performance of Sr0.9La0.1TiO3 and Sr0.25Ca0.25Na0.25Pr0.25TiO3 perovskite–based catalysts were studied under different radiation types (simulated solar, LED, and UV radiation) for removal of metoprolol and pindolol. The results showed that both materials effectively removed metoprolol and pindolol, with the highest degradation efficiency observed under UV radiation. The degradation efficiency of metoprolol went up to 30% using Sr0.9La0.1TiO3 and Sr0.25Ca0.25Na0.25Pr0.25TiO3 using all mentioned radiation types. Pindolol was degraded more efficiently, using Sr0.9La0.1TiO3 68%, 94%, and 100% of pindolol was degraded after 240 min, under SSI, UV-LED, and UV irradiation. Using Sr0.25Ca0.25Na0.25Pr0.25TiO3, degradation efficiency was 65%, 84%, and 93%, under SSI, UV-LED, and UV irradiation, respectively. The chemical oxygen demand showed that these materials were highly efficient in mineralizing metoprolol and pindolol as well as their intermediates. The mechanisms behind the degradation of metoprolol using perovskite catalysts are complex. Still, ongoing research has indicated that the degradation mechanism occurs through hydroxylation of the aromatic ring or side chains. A similar degradation pathway is suggested for the degradation of pindolol, including opening an indol ring at the nitrogen atom site.

Optimisation of electrical conductivity and dielectric properties of Sn4+-doped (Na0.5Bi0.5)TiO3 perovskite

The structural, microstructural, dielectric, and conductivity properties of Tin modified Sodium Bismuth Titanate (Na0.5Bi0.5)(Ti1-xSnx)O3, where x (mol%) = 0%, 1%, 3% (labeled as NBT, NBTS1, and NBTS3, respectively) were experimentally investigated in this paper. In this regard, the solid-state reaction process was used to prepare polycrystalline materials, where sintering was performed at 1100 °C for 3 h under atmospheric air. As a result, X-ray diffraction confirms, as it seems, the presence of a rhombohedral phase (R3c) in all compositions at room temperature. The electrical properties of the compositions are also studied using complex impedance spectroscopy (CIS). Subsequently, at room-temperature, doping 1% of Sn4+ in the NBT perovskite reduces the dielectric loss from 4.4 × 10−2 to 3.43 × 10−2 at 1 MHz. Moreover, it is around 3.05 × 10−2 at 93.6 °C and 1 MHz for NBTS3. Sn4+ significantly doping improved electrical conductivity. Therefore, at 10 Hz and 450 °C, the electrical conductivity of NBTS3 (σac = 8.76 × 10−3 S.m−1) is 61.26 times that of pure NBT (σac = 1.43 × 10−4 S.m−1). Joncher's power law investigates the conduction mechanism's nature; (i) the decreasing variation of the exponent s1 with temperature suggests that the NBT compound is characterized by the CBH (Correlated Barrier Hopping) model. On the other hand, for NBTS1 and NBTS3 (ii), the increase in s1 and s2 parameters under temperature indicates that the NSPT (non-overlapping small polaron tunneling) model is the most dominant. In this work, all tested compounds exhibit a sort of ferroelectric relaxation behavior. Our results demonstrate that doped materials can be applied to solid oxide fuel cells.

High-Entropy Enhanced Microwave Attenuation in Titanate Perovskites.

High-entropy oxides (HEOs), which incorporate multiple-principal cations into single-phase crystals and interact with diverse metal ions, extend the border for available compositions and unprecedented properties. Herein, a high-entropy-stabilized (Ca0.2 Sr0.2 Ba0.2 La0.2 Pb0.2 )TiO3 perovskite is reported, and the effective absorption bandwidth (90% absorption) improves almost two times than that of BaTiO3 . The results demonstrate that the regulation of entropy configuration can yield significant grain boundaries, oxygen defects, and an ultradense distorted lattice. These characteristics give rise to strong interfacial and defect-induced polarizations, thus synergistically contributing to the dielectric attenuation performance. Moreover, the large strains derived from the strong lattice distortions in the high-entropy perovskite offer varied transport for electron carriers. The high-entropy-enhanced positive/negative charges accumulation around grain boundaries and strain-concentrated location, quantitatively validated by electron holography, results in unusual dielectric polarization loss. This study opens up an effective avenue for designing strong microwave absorption materials to satisfy the increasingly demanding requirements of advanced and integrated electronics. This work also offers a paradigm for improving other interesting properties for HEOs through entropy engineering.

Correlating hidden local structural distortion with antiferroelectric-ferroelectric transition in PbZrO3-based perovskites

Externally stimulated antiferroelectric-ferroelectric (AFE-FE) transition makes AFE materials attractive for many applications ranging from energy storage to sensing. This transition-mediated macroscopic electrical characteristics have been extensively investigated, yet the underlying structural evolution remains poorly understood. Herein, we study the local- and long-range structural evolutions in the Nb-doped Pb(Zr,Sn,Ti)O3 perovskites by in-situ X-ray total scattering and diffraction, which show three different types of AFE-FE transitions. The evolution of long-range structure from diffraction and local structure identified by atomic pair distribution function (PDF) are consistent well with the phase transition behavior indicated by macroscopic polarization/strain measurements, while discrepancies exist. Interestingly, frequently employed long-range structure picture that the uniform AFE pseudo-tetragonal to FE rhombohedral transformation is insufficient to understand the distinct composition-dependent AFE-FE transition behaviours. Instead, the reversibility of this transition correlates with the chemically sensitive local atomic displacements revealed by newly developed in-situ PDF. The critical electric field of transition is associated with the local structural differences between the AFE and FE state. The macroscopic electrostrains can be well estimated by the phase transition associated lattice strain and domain alignment from in-situ synchrotron XRD data, while the local strains calculated from in-situ PDFs are found to be much lower. These results provide a fresh insight into the AFE-FE transition, and advance the understanding of structure-property relationships in AFE materials.

Synthesis and photoluminescence properties of perovskite-structure Ba0.5Sr0.5TiO3: Sm3+ phosphors

Abstract Rare-earth ions doped luminescent materials have excellent optical properties and low energy consumption, which are widely used in optoelectronic devices. In this work, Sm3+-doped Ba0.5Sr0.5TiO3 perovskite phosphors were prepared by a convenient high-temperature solid-reaction method. A strong orange-red luminescence appeared at 600 nm, corresponding to the energy-level transition of 6H5/2 → 4F7/2. The optimal concentration of Ba0.5Sr0.5−x TiO3: xSm3+ was determined to be around x = 0.08. The forbidden band width and the fluorescence lifetime of Ba0.5Sr0.5TiO3: Sm3+ are 3.15 eV and 2.7 μs, respectively. The CIE coordinates are (0.509, 0.476). The as-prepared orange-red perovskite phosphors are expected to be used in white light–emitting diode (LED) devices.

Characteristics of (Sr0.92Y0.08)0.85Ti1-XNixO3-

Perovskite with A-site deficiency(A1-xBO3) is promising candidate due to introduction of oxygen vacancy for ionic conductivity and nano-sized exsolution of B component with metal phase for catalytic activity. In this study, Ni-doped Sr0.92Y0.08TiO3 perovskite has been investigated to improve the catalytic activity for CO2 dry internal reforming of methane in solid oxide fuel cells. (Sr0.92Y0.08)0.85Ti1-xNixO3- \U0001d6ff (x=0.05, 0.10, 0.15, 0.20) perovskite with A-site deficiency is prepared by pechini method and compared to stoichiometric Sr0.92Y0.08Ti1-xNixO3- \U0001d6ff (SYTN15) perovskite. The physical and physicochemical characteristics of the synthesized powders are analyzed by GC, XRD, BET, TEM, XPS, and TPO. (Sr0.92Y0.08)0.85Ti0.85Ni0.15O3- \U0001d6ff (SYTN(+)15) shows the highest methane conversion with 93% and carbon dioxide conversion with 86%. In addition, the SYTN(+)15 results to the lowest decreasing rate of the methane conversion with 1.86% drop for 50h. The SYTN(+)15 shows better catalytic performance by 10% for dry reforming of methane (DRM) comparing to the SYTN15. The cell performances of the SYTN(+)15 and the SYTN15 are 60.05mW/cm2 and 28.50mW/cm2, respectively. Consequently, A-site deficiency catalyst, SYTN(+)15 exhibits excellent catalytic activity for DRM and sufficient electrochemical property for SOFC anode materials.

Structural and electrical properties of bismuth sodium titanate ceramic

Single-phase lead-free Bi0.5Na0.5TiO3 (BNT) perovskite ferroelectric ceramic was produced using a solid-state reaction method. A detailed investigation of the structural and electrical properties of BNT ceramic is conferred. According to phase analysis employing Rietveld refined X-Ray diffraction, the crystal structure is single phase with rhombohedral (R3C) symmetry. Raman spectra measurement also confirms the rhombohedral structure of BNT by originating numerous peaks from the TiO6 octahedron. The ferroelectric character of the BNT sample was established by a hysteresis loop measurement of polarisation vs electric field (P-E). The remnant polarisation (Pr) and coercive field (Ec) have characteristic values of 1.63 μC/cm2 and 29.91 kV/cm, respectively. The ferroelectric phase change is seen in the temperature-dependent dielectric research, with a transition temperature of 323°C. The compound possessed a low value of tanδ even at a high temperature (500°C) at 1 MHz. The prepared sample exhibited excellent dielectric characteristics from room temperature to high temperatures, making it ideal for various applications.

Highly tunable multifunctional rare earth based Bi0.5-xCexNa0.5TiO3 perovskites via site selective doping engineering

The high-quality lead-free relaxor-ferroelectric Bi0.5-xCexNa0.5TiO3 (BCNT) electroceramics were fabricated through the modified Pechini method. The influence of cerium dopant on the phase transition, microstructure and shrinkage performances are studied systematically. The temperature played an important role in improving the grain size of the ceramics. The density of heat-treated samples was 4.503, 4.564 and 4.599 g/cm3. Density value decreased due to cerium doping, but a reverse phenomenon occurred to sintering temperature. The crystallinity BCNT samples sintered at 900 and 1100 °C were calculated as 87.11 and 92.93%, respectively. BCNT ceramics showed good performances like increased grain size and significant changes in shrinkage% measurements. The reported measures could be advantageous in case BNT based materials for commercial applications like electrode systems and multi-layered structures.
