GRAIN BOUNDARY INSULATED SEMICONDUCTOR CERAMIC AND CERAMIC CAPACITOR USING THE SAME
PROBLEM TO BE SOLVED: To provide a grain boundary insulated semiconductor ceramic, which can provide high relative permittivity, shows little change in relative permittivity over a wide frequency range, and has a wide applicable range, and to provide a ceramic capacitor using the same.SOLUTION: The grain boundary insulated semiconductor ceramic at least comprises any one or more of oxide components represented by SrTiOand BaTiO, and a lithium ion conductive oxide component represented by (Li,La)TiO. Preferably, when contents of SrTiO, BaTiO, and (Li,La)TiOare denoted by x moles, y moles, and z moles, respectively, and a total of these (=x+y+z) is taken as 100, the following formulas hold: 20≤x+y≤98; x≥0; y≥0; and 2≤z≤80.SELECTED DRAWING: Figure 1
【課題】 高い見掛比誘電率が得られ、広い周波数域において比誘電率の変化が小さく、適用可能な範囲の広い粒界絶縁層型半導体セラミックおよびそれを用いたセラミックコンデンサを提供する。【解決手段】 少なくとも、ＳｒＴｉＯ３及びＢａＴｉＯ３で示される酸化物成分の何れか１以上と、(Ｌｉ,Ｌａ)ＴｉＯ３で示されるＬｉイオン伝導性酸化物成分を含み、好ましくは、ＳｒＴｉＯ３の含有量をｘモル、ＢａＴｉＯ３の含有量をｙモル、(Ｌｉ,Ｌａ)ＴｉＯ３の含有量をｚモルとし、その合計（＝ｘ＋ｙ＋ｚ）を１００とした時に、下式が成り立つ。２０≦ｘ＋ｙ≦９８ｘ≧０ｙ≧０２≦ｚ≦８０【選択図】図１
