Effect of Sb2O3 on the electrical properties of Ba0.9Ca0.1Zr0.1Ti0.9O3 ceramics fabricated using nanocrystals seed

บทคัดย่อ ( Abstract )

This work was to investigate the effects of antimony oxide (Sb2O3) on the electrical properties of Ba0.9Ca0.1Zr0.1Ti0.9O3 (BCZT) ceramics and was prepared by adding 1 mol% of BCZT nanocrystals. The seed is nanocrystals of BCZT which was synthesized by the molten salt method. The ceramics powders were prepared by the mixed oxide method using BaCO3, CaCO3, ZrO2, TiO2 as starting materials, and the BCZT seed was added as nanocrystal for induce phase transition. They were doped with x mol% Sb2O3 (x = 0.0–0.5). Results indicated that all samples show pure perovskite phase. The Sb2O3 enhanced the electrical properties of the ceramic systems. Excellent values of a dielectric constant (er) at room temperature (Tr) were 4086 with sample of x = 0.5, and at Curie temperature (Tc) was 15,485 for samples with x = 0.1. The highest remnant polarization (Pr), piezoelectric charge coefficient (d33), piezoelectric voltage coefficient (g33), electromechanical coefficient for planar mode (kp) and thickness mode (kt) values were 6.3 lC/cm2, 346 pC/N, 15.6 9 10-3 Vm/N, 42 and 41 %, respectively, which were obtained for the sample of x = 0.2 mol% Sb.
