【摘要】 本文研究了４Ｂｉ２Ｏ３·Ｂ２Ｏ３助熔剂对ＰＬＺＴ瓷料的降温效果以及ＢａＳｎＯ３的固溶和Ｂａ２＋的Ａ位取代对掺Ａｇ＋的ＰＬＺＴ反铁电组分的改性作用，获得了中温烧结的ＰＬＺＴ系Ｘ７Ｒ瓷料．其主要性能指标达到：ε２９８Ｋ＝２０００±１００；ｔｇδ＜５０×１０－４；ρｖ＞１０１３Ω·ｃｍ；△ε／ε２９８Ｋ＜±１０％；Ｅｂ＞１．１×１０４ｋＶ／ｍ；Ｔｓ＝１３４３～１３９３·Ｋ更多还原

【Abstract】 Effect on PLZT ceramics material by using 4Bi2O3·B2O3 flux and modification effect of BaSnO3 dissolution and substitution of Ba2+ for A site on Ag-doped PLZT AFE composition are studied. Mid-temperature sintering PLZT X7R ceramics material is obtained,whose main specifications are as following:ε298K = 2000 ± 100;tgδ<50×10-4;△ε/ε298K<±10%;ρv>1013Ω·cm; b>1.1×104kV/mm; Ts= 1343￣ 1393K更多还原
