It was shown that axial pressure strongly changes the dielectric and ferroelectric properties of Na 0.5 Bi 0.5 TiO 3 ceramic. This includes: (i) the shift of rhombohedral–tetragonal phase transition to higher temperature, suppressing the dielectric dispersion, and reduction of thermal hysteresis of the electric permittivity which can be evidence of transition nature changes to second order one, and (ii) the decrease of polarization in the long‐range ferroelectric phase and the shift of phase decay temperature to higher temperature. Also the thermodynamic parameters of the rhombohedral–tetragonal phase transition were estimated.
