Abstract

-The ternary system of yBiGaO₃-(1-x-y) BiScO₃-xPbTiO₃ (BGS-PT) ceramics was prepared by using conventional mixing oxide process. X-ray diffraction analysis reveals that BGS-PT ceramics show the perovskite structure. The Curie temperature of BGS-PT ceramics was found to be increased with increasing of BiGaO₃ content. However, more BiGaO₃ content would lead to sharply decreased piezoelectric properties of BGS-PT ceramics and the secondary phase would be formed in BGS-PT system. BGS-PT ceramics with x, y=0.56, 0.19 shows a high Curie temperature T_c and large piezoelectric constant d₃₃ of 501degC and 152 pC/N, respectively. The high-T_c of BGS-PT ceramics with the useable piezoelectric properties suggested those future high-temperature applications.
