Domain and heterophase states in lead-free Ba(CexTi1–x)O3 solid solutions

Аннотация

The correlation between domain (twin) structures and heterophase states in Ba(Ce_xTi_1–x)O₃ solid solutions near the morphotropic phase boundary is established. The role of individual domains in the formation of structures with two ferroelectric phases is revealed, and the volume concentrations of these phases are calculated for x = 0.02 and x = 0.07 with the complete relaxation of mechanical stresses. The calculated and experimentally determined volume phase concentrations are in good agreement.
