摘要：

Dielectric measurements, carried out on Na0.5Bi0.5TiO3 ceramics, revealed behaviour-dependency of both temperature and frequency. Two relaxation processes for frequencies from 20 Hz to 1 MHz are observed. The first relaxation process could be attributed to space charge. The second is low-frequency dipolar relaxation in the frequency range up to 100 kHz at 833 K and close to 0.5 kHz at 493 K, and could be related to the existence of polar regions in Na0.5Bi0.5TiO3-.
