Control of the temperature hysteresis and diffuse dielectric anomaly in the temperature range of the ferroelectric-antiferroelectric phase transition in PbZr1-xTixO3 (0.03 <= x <= 0.05) ceramics

摘要

The magnitudes of the temperature hysteresis and diffuse dielectric anomaly corresponding to the transition from the antiferroelectric phase to the ferroelectric phase in PbZr1-xTixO3 (0.03 <= x <= 0.05) ceramics can be reversibly changed by varying the temperatures of heating and cooling in the course of thermocycling The results obtained indicate that the anti ferroelectric-ferroelectric transition in the PbZr1-xTixO3 ceramics materials is a smeared first-order phase transition.
