Abstract

The influence of alternating (ac) and direct current (dc) fields on the structural and dielectric properties of 001 textured Na0.5Bi0.5TiO3-7%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. (C) 2013 AIP Publishing LLC.
