Abstract

Different compositions of (1 - x)PbZrO3-xBa(Mg 1/3Nb2/3)O3 (PZ-BMN) system, with x = 0.00-0.50, were synthesized using the columbite precursor method. The effects of BMN content on phase transition, electrical and thermal properties of PbZrO3 ceramic were investigated. The composition range and stability of the ferroelectric phase in perovskite PZ-BMN system can be improved by optimizing BMN substitution. Phase transition behavior of various solid solutions of PZ compositions can be predicted by a phase diagram established from the average electronegativity difference versus tolerance factor of the end members. © 2014 the Partner Organisations.
