Abstract :
The lead zirconate stannum titanate antiferroelectric ceramics(abbr. as PZST) were fabricated by using convenient solid sintering methods. It was of double electric hysteresis and the switching electric fields between of antiferroelectric and ferroelectric phases could be modulated with material composition change. The discharge curves were measured. The results showed that antiferroelectric ceramics is of higher density of store energy and rapider discharge speed compared to the linear dielectric materials. Antiferroelectric ceramics is suitable to high power discharge capacitor.
