PIEZOELECTRIC CERAMICS

KIKUTA KOICHI / ISONO JUN / KOBAYASHI YASUISA / SUZUKI YOSHIBUMI

PROBLEM TO BE SOLVED: To provide a non-lead-based piezoelectric ceramics which improves material strength and voltage resistance properties and is configured to decrease a voltage necessary for driving.SOLUTION: A piezoelectric ceramics contains: a perovskite compound represented by a composition formula (KNa)(NbTa)O(in the formula, 0

【課題】材料強度及び耐電圧性を向上すると共に、駆動に必要な電圧を低減した、非鉛系の圧電セラミックスを提供すること。【解決手段】圧電セラミックスが、組成式（ＫｘＮａ１−ｘ）ｙ（Ｎｂ１−ｚＴａｚ）Ｏ３（式中、０＜ｘ≰１、０＜ｙ＜１、０≰ｚ≰０．５）で表されるペロブスカイト化合物、Ｋ、Ｃｏ、及びＴａを含む酸化物からなる焼結助剤、及び、銀の化合物、を含有し、前記ペロブスカイト化合物、及び、前記焼結助剤に含まれるＣｏ原子の合計１００モル％に対し、前記銀の化合物がＡｇ原子基準で１．０〜４．０モル％である。【選択図】なし
