摘要：

The results of investigations of the structure of BaTiO3 under thermobaric effects at constant volume are presented. The pressure and temperature values of the structural phase transition from the tetragonal ferroelectric phase to the cubic paraelectric phase at constant volume are determined. The temperature and pressure coefficients for the various phases of BaTiO3 are found. The Birch–Murnaghan equations of state are calculated and the parameters B0 and B′ are established. © 2017, Pleiades Publishing, Ltd.
