Structural and dielectric properties of (1-x)Bi(Ni1/2Ti1/2)O3-xPbTiO3 ceramics with the morphotropic phase boundary composition

(1-x)Bi(Ni1/2Ti1/2)O-3-xPbTiO(3) (BNT-xPT, 0.42 a parts per thousand currency signaEuro parts per thousand x a parts per thousand currency signaEuro parts per thousand 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 (T (c)) of 410 A degrees C and good piezoelectric properties, d (33) similar to 230pC/N, k (p) similar to 40 % and k (t) similar to 22 %. For 0.46 a parts per thousand currency signaEuro parts per thousand x a parts per thousand currency signaEuro parts per thousand 0.50 samples, it can be found that depolarization temperature is around 350 A degrees C by thermal depoling method.
