The properties of (1-x)(0.5PZT-0.5PFW)-xPFN ceramics

ABSTRACT

The ceramic samples of solid solution (1-x)[0.5(PbZr_0.53Ti_0.47O₃)-0.5(PbFe_2/3W_1/3O₃)]-x(PbFe_1/2Nb_1/2O₃) [i.e. (1-x)(0.5PZT-0.5PFW)-xPFN] with x = 0; 0.1; 0.2 have been obtained by conventional ceramic technology using the free sintering (FS) method from PbO, ZrO₂, TiO₂, Fe₂O₃, WO₃ and Nb₂O₅ oxides. Basing on the literature data for individual components, it can be expected that this material ought to have interesting multiferroic properties. The presented work is the first step in obtaining and investigating this solid solution. In the presented paper, the technology and the results of investigations of EDS, XRD, the microstructure of fractured samples, dielectric permittivity v.s. temperature, and d.c. electric conductivity are presented.
