Temperature-induced transitions from tetragonal antiferroelectric phase to cubic paraelectric phases and low-temperature section frequency dispersion were observed.
结果表明:在温度场下,随着温度的升高,PbLa(Zr,Sn,Ti)O3陶瓷从四方反铁电相(AFET)转变为立方顺电相(PEC),在低温段出现频率弥散现象;在压力场下,随着等静压力的增加极化过的AFE陶瓷发生FE/AFE相变,同时伴随突然的释放电荷过程;在一定的等静压力下,经极化后变为铁电体的PbLa(Zr,Sn,Ti)O3陶瓷在温度的诱导下会转变为反铁电相,最后转变为顺电相;随着等静压力的增加,铁电/反铁电转变温度降低,反铁电/顺电转变温度上升。
