Effect of Y-doping on the piezoelectric properties of (1-z)BiScO3-zPbTiO3 high-temperature piezoelectric ceramics

摘要：

(1-x)Bi(Sc1-yYy)O3-xPbTiO3 (BSYPTx/y) ceramics were prepared by the conventional mixed oxide method. It was found that the morphotropic phase boundary (MPB) between rhombohedral and tetragonal phase of BSYPTx/y system was moved to the lower PT content with increasing of BiYO3 content. The Curie temperature (TC) near MPB of BSYPTx/y ceramics was found to increase with increasing of BiYO3 content. However, the piezoelectric properties (d33 and kp) decreased with increasing of BiYO3 content. BSYPTx/y ceramics with x=0.56, y=0.2 showed a high TC of 490 ℃ and a large d33 of 147 pC/N.
