摘要：
(1-x)Bi(Ni1/2Ti1/2)O3-xPbTiO3 (BNT-xPT, 0.42 ≤ x ≤ 0.52) ceramics were prepared by the conventional mixed oxide method. With the increase of PT content, a change from rhombohedral phase to tetragonal phases, and while the morphotropic phase boundary (MPB) composition is located in the range of x = 0.46–0.48. For x = 0.46 sample, it exhibited a high Curie temperature (Tc) of 410 °C and good piezoelectric properties, d33 ~230pC/N, kp ~40 % and kt ~22 %. For 0.46 ≤ x ≤ 0.50 samples, it can be found that depolarization temperature is around 350 °C by thermal depoling method.
