Abstract

Phase transition in the (1-x)PbTiO3-xA(B 2 3Nb 1 3)O3 (A=La, Bi; B=Zn,Mg) solid solution systems has been investigated by means of x-ray diffraction, dilatometric and dielectric measurements. Complete solid solutions with a perovskite structure are formed in the ranges of 0 < x < 0.7 and 0 < x < 0.3 for the PbTiO3-La(B 2 3Nb 1 3)O3 and PbTiO3-Bi(B 2 3Nb 1 3)O3 systems, respectively. The tetragonal distortion at room temperature decreases with increasing the La(B 2 3Nb 1 3)O3 or Bi(Mg 2 3Nb 1 3)O3 molar fraction, while it increases with the Bi(Zn 2 3Nb 1 3)O3 content. The ferroelectric Curie temperature determined by the dielectric and/or dilatometric measurements decreases rapidly with the increase of the La(B 2 3Nb 1 3)O3 content, but slightly decreases or increases with Bi compounds in the case of the Bi(Mg 2 3Nb 1 3)O3 or Bi(Zn 2 3Nb 1 3)O3 series, respectively.
