Abstract

Temperature dielectric behavior in oxidized and non-oxidized PZT (60/40) and PZT (40/60) ceramics were analyzed in a frequency and temperature range of 1 kHz-10 MHz and from 15 to 400 K, respectively. The results revealed an anomalous dielectric behavior at temperatures closed to 250 K in
oxidized and non-oxidized PZT samples. Temperature polarization behavior in pyro-electric measurement
shows monotony changed in the same temperature range. Dipolar behavior could be the cause of detected
anomaly.
Keywords: perovskite structure, temperature dielectric behavior, oxidation, reduction, PZT.
