Small hysteresis and high energy storage power of antiferroelectric ceramics

In this paper, modified Pb(Zr,Ti)O-3(PZT) antiferroelectric (AFE) ceramics system was investigated by traditional solid state method. It was observed that the effect of different contents of Zr/Sn, Zr/Ti on modified PZT antiferroelectrics. With increasing Zr/Sn content, the E-AFE (electric field of AFE phase to ferroelectric (FE) phase) value was enlarged. The phase switch field was reduced from FE to AFE (E-FA). The hysteresis loops were changed from "slanted" to "square"-types. With increasing Zr/Ti concentrate, the E-AFE value, and also the E-FA was enlarged, while the hysteresis switch Delta E was reduced. The hysteresis loops was from "square" to "slanted"-types. The samples with square hysteresis loops are suitable for energy storage capacitor applications, the composition of ceramics was Pb-0.La-97(0.02)(Zr0.90Sn0.05Ti0.05)O-3, which have the largest energy storage density similar to 4.426J/cm(3) at 227 kV/cm, and Delta E was similar to 80 kV/cm, energy efficient eta was about 0.612.
