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 Tc and large piezoelectric constant d33 of 501degC and 152 pC/N, respectively. The high-Tc of BGS-PT ceramics with the useable piezoelectric properties suggested those future high-temperature applications.
