DIELECTRIC CERAMIC COMPOSITION, DIELECTRIC MATERIAL AND MULTILAYER CERAMIC CAPACITOR INCLUDING THE SAME
PROBLEM TO BE SOLVED: To provide a dielectric ceramic composition having guaranteed X8R temperature characteristics and reliability, a dielectric material, and a multilayer ceramic capacitor including the same.SOLUTION: A multilayer ceramic capacitor includes a dielectric ceramic composition including a barium titanate-based major component and a minor component. In an X-ray diffraction analysis after sintering, when the (110) peak of BaTiOis set as 1.00, a ratio of a peak of a pyrochlore phase (RETiO) at about 30.5 degrees with respect to the peak of BaTiOsatisfies 0.02 or less, where RE is at least one or more of Y, Dy, Ho, Sm, Gd, Er, La, Ce, Nd, Tb, and Pr.SELECTED DRAWING: Figure 1
【課題】Ｘ８Ｒ温度特性及び信頼性が保証される誘電体磁器組成物、誘電体材料及びそれを含む積層セラミックキャパシタの提供。【解決手段】チタン酸バリウム系主成分及び副成分を含み、焼結後の線回析法分析において、ＢａＴｉＯ３の（１１０）ピークを１．００に換算したとき、上記ＢａＴｉＯ３のピークに対する３０．５度付近のパイロクロア相（ＲＥ２Ｔｉ２Ｏ７：ＲＥはＹ、Ｄｙ、Ｈｏ、Ｓｍ、Ｇｄ、Ｅｒ、Ｌａ、Ｃｅ、Ｎｄ、Ｔｂ又はＰｒのうち一つ以上）のピークの比率が０．０２以下を満たす誘電体磁器組成物である積層セラミックキャパシタ。【選択図】図１
