摘要
采用爆炸冲击波作用于贮存有电极化能量的铁电体,迫使其转变成反铁电体,可释放出巨大电能量,用于一次性的高压、大功率脉冲电源。本工作研究了锆钛酸铅反铁电材料在电场、压力、温度作用下的反铁电-铁电相变性质,介绍了在爆炸冲击波作用下铁电向反铁电转变过程中电量的输出特性。
A ferroelectrics could release total electric polarization energy during it is transformed to antiferroelectrics,and that was used to high electrical power supply. The transformations between of antiferroelectric and ferroelectric phases induced with electric field, pressure, and temperature were studied for Pb(Zr,Ti)O_3 family. The characteristics of electric power under shock-wave compression were introduced in the work.
