摘要：

Ba(ZrxTi1-x)O-3 (0 <= x <= 0.12), step = 0.02) ceramics have been prepared by the solid solution reaction method. The Curie temperature decreased nonlinearly from 131 to 74 degrees C with increases x from 0 to 0. 12 in BZT ceramics. While the diffusion factor increase from 1.06 to 1.64 with increases x from 0 to 0. 12, implying a composition-induced diffuse transition. The phase transition temperature of tetragonality to orthorhombic structure (To-t) increases with increasing of Zr content, forming a pinched phase transition. (c) 2009 Acta Materialia Inc.
