Abstract
The concept of the mechanism of formation of morphotropic boundaries in T−x phase diagrams of solid solutions of complex oxides with the perovskite structure has been formulated. This concept is illustrated by calculation of the conditions for existence of morphotropic phase transition in a quasy-binary solid solution of the PbZr1 − x Ti x O3 and (1 − x)PbMg1/3Nb2/3O3 + xPbTiO3 compositions.
