摘要：

Solid solutions in the (x)PbTiO3-(1-x)Bi(Zn3/4W1/4)O-3 system have been examined by x-ray diffraction, dielectric measurements, and thermal analysis. Bi(Zn3/4W1/4)O-3 increases the tetragonality and Curie temperature of PbTiO3 which reach a value of 1.08 and 530 degrees C, respectively, at the limit of the single-phase perovskite forming region (x similar to 0.8). The observation of a sustained increase in the tetragonality in this system is similar to the behavior of the (x)PbTiO3-(1-x)Bi(Zn1/2Ti1/2)O-3 system and highlights the unique properties of Bi-based systems when the B sites contain high concentrations of highly polarizable cations.
