Abstract

Requirements for mixture formation between A⁺²B⁺⁴O₃ and A⁺³B⁺³O₃ perovskite compounds were examined. The tolerance factor as well as the differences in size and valence of A and B site ions were considered as critical factors. A valence difference is found to be a necessary condition for the mixture formation.
