摘要：
(1-x)Bi(Sc1-yYy)O(3-)xPbTiO(3) (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 (T-C) near MPB of BSYPTx/y ceramics was found to increase with increasing of BiYO3 content. However, the piezoelectric properties (d(33) and k(p)) decreased with increasing of BiYO3 content. BSYPTx/y ceramics with x = 0.56, y = 0.2 showed a high T-C of 490 C and a large d(33) of 147 pC/N.
