中文摘要: 对不同锆锡比的Pb_0.97La_0.02（Zr_0.12+xSn_0.7-xTi_0.18）O₃铁电陶瓷的铁电和相变行为进行了系统的研究，阐明了组成和温度对PLZST铁电陶瓷的相变效应的影响规律.研究结果表明：PLZST铁电陶瓷均呈现典型的铁电体电滞回线.随着温度的升高，PLZST12/70/18，PLZST52/30/18，PLZST62/20/18发生铁电-顺电相变，PLZST22/60/18，PLZST32/50/18，PLZST42/40/18为铁电-反铁电-顺电相变.

Abstract:Ferroelectric and phase transition performance of Pb_0.97La_0.02(Zr_0.12+xSn_0.7-xTi_0.18)O₃ ceramics with various Zr:Sn ration are systematically investigated,which demonstrates the effect of composition and temperature on the phase transformation of PLZST ferroelectric ceramics.The result shows that PLZST ceramics present typical ferroelectric electric hysteresis loop.With the temperature increasing,PLZST12/70/18,PLZST52/30/18 and PLZST62/20/18 ceramics experiences ferroelectric to paraelectric phase transition,while PLZST22/60/18,PLZST32/50/18 and PLZST42/40/18 experiences phase transitions from ferroelectric to antiferroelectric phase,and antiferroelectric to paraelectric phase.
