Abstract

The influence of alternating (ac) and direct current (dc) fields on the structural and dielectric properties of [001]_PC textured Na _0.5Bi_0.5TiO₃-7%BaTiO₃ (NBT-7%BT) ceramics has been investigated. X-ray diffraction measurements revealed that the depolarization at temperature T_d in poled samples resulted from a tetragonal → pseudo-cubic transition on heating. Moderate ac drive and dc bias had opposite influences on T_d: ac drive decreased the T _d, whereas dc bias increased it. These investigations suggested an effective method to expand the working temperature range of NBT-x%BT textured ceramics to a high temperature.
