Polarization stability in lead-free Na0.5Bi0.5TiO3 ceramics: Grain size and temperature effects

The stability of the polarization state in Na0.5Bi0.5TiO3 (NBT) ceramics has been a long-standing problem for its use in piezoelectric applications at elevated temperatures. It has been generally believed that the polarization state, depolarization temperature, and depolarization process are all lin...
