Abstract

Complex perovskite Pb(Mg1/₂W1/₂)O₃ (PMW) is known to exhibit antiferroelectric behavior. In this work, two new solid solutions of (1-x)Pb(Mg1/₂W1/₂)O₃- xPb(B′1/₂W1/₂)O₃ (B = Zn²⁺ or Mn²⁺) of perovskite structure have been prepared by solid state reaction method. X-ray diffraction analysis indicates that when x ≤ 0.2, both systems crystallize in an orthorhombic (Pmcn) structure. As x increases, the perovskite structure becomes less stable and secondary phases start to form. Our results show that isovalent substitutions of Zn²⁺ and Mn ²⁺ for Mg²⁺ at high concentration resulted in different secondary phases. The structural stability of the perovskite phase and its influence on crystal symmetry are discussed.
