铁电陶瓷相变特性及其应用研究

Phase transition and applications of Ferroelectric ceramics

　　铁电/反铁电相界附近的PZT95/5型铁电陶瓷材料具有丰富的相结构，在电场、温度、应力作用下可诱导发生反铁电—铁电相变，是研究铁电体相结构、铁电相变理论以及发展能量转换等多种应用的优选材料之一。利用PZT95/5型铁电陶瓷材料在应力、电场和温度条件下的相变特性开展了爆电换能、反铁电储能、热释电红外探测等方面的应用研究工作。

　　PZT 95/5 ferroelectric ceramics and its derivants are of significant scientific and technological interest because of their rich phase structures, field-induced phase transitions and nonlinear responses. Based on the field (such as stress, electric field and temperature) -induced phase transition behaviors, applications of PZT-based ferroelectric ceramics in shock-induced power supply, energy storage and pyroelectric detector are ongoing.
