摘要：
The relaxation behaviors of barium titanate ceramics were investigated in the temperature range of 200-450 degrees C. The diffuse dielectric anomalies were described by the universal dielectric relaxation law (UDR) and polaron theory. It is indicated the dielectric relaxation of barium titanate at high temperatures is associated with the hopping localized oxygen vacancies.
