Abstract
The nanomultiferroic material which is synthesized in this research used sol-gel method. The research used weight ratio of BaTiO3: BiFeO3 of 2: 1. Gel formed after heating at 80-90°C was calcined at 350°C for 4 hours and then sintered at 700,750 and 800°C for 2, 4 and 6 hours respectively. Powder produced after sintering was characterized by X-Ray Diffraction (XRD) test using XRD Phillips PW 1835 type, 20°-100° diffraction angle and CuKα, electric polarization properties test and particle size measurement using Particle Size Analyzer of Beckman Coulter DelsaTM Nano instrument. From the characterization results, it is obtained that the dominant phase is Barium Bismuth Iron (III) Oxide (BaBiFe2O5). Electrical polarization properties such as remanent, coersivity and saturation reach maximum value at sinter temperature of 750° C and sinter time of 6 hours. This result is supported by the smallest particle size of powder (54-57 nm) and also supported by the largest number of dominant phase (98.79%) at same condition.
Highlights
The nanomultiferroic material is a material with nano particle size (
From X-Ray Diffraction (XRD) test results, there are obtained graphs of XRD patterns for all samples, one example shown in Figure 2 for sinter temperature of 750oC and sinter time of 6 hours
Powder synthesized by so-gel method for all variables is nanoparticle because the size < 100 nm
Summary
The nanomultiferroic material is a material with nano particle size (
