摘要
利用轻气炮作为加载手段,对PZT-95/5铁电陶瓷进行冲击波压缩,以实现陶瓷受激相变放电。在涵盖了PZT-95/5陶瓷的相变压力点及雨贡纽弹性极限压力点的加载压力区间内,对其放电特性进行了实验研究。获得了不同加载压力下的PZT-95/5铁电陶瓷耐电击穿强度及剩余极化强度等特征参数,并分析和讨论了PZT-95/5在不同加载压力作用下的放电特性。
With a light gas gun for generating the shock wave loading, the PZT-95/5 ferroelectric ceramic has been shock compressed to induce a phase transformation for electric depoling. Under the pressures ranging from the phase transition point to the Hugoniot elastic limit, the depoling property of PZT-95/5 ferroelectric ceramic has been experimentally studied. Results including the breakdown voltage and the charge release amount have been measured. The depoling characteristic and its mechanism have been discussed.
