Thermo- and magnetic-field-induced dynamics of first-order ferroelectric and antiferroelectric phase transitions are considered, taking into account the inertia effect. The width and velocity of interphase boundaries are calculated as functions of temperature and magnetic field strength. The results obtained here are essentially different from those of the Ginzburg-Landau theory and of the case of the small kinetic energy term, and they may also be used for the description of the kinetics of ferroelectric phase transitions in high-temperature superconductive perovskites.
