Abstract

The solid solutions of the (1 – х)BiFeO₃–x/2PbFe_1/2Nb_1/2O₃–x/2PbFe_2/3W_1/3O₃ system in the concentration range 0.05 ≤ х ≤ 0.50 were produced by solid state method and sintering using conventional ceramic technology. In the range 0.25 < x < 0.35, a morphotropic phase transition from the rhombohedral phase to the cubic phase was found. The difference in symmetry when “scaling” the material is shown. The influence of PbFe_1/2Nb_1/2O₃ and PbFe_2/3W_1/3O₃ on the grain structure formation was established.
