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 dielectric ceramic composition includes: a barium titanate-based major component; and a minor component. In a fine structure obtained after sintering the ceramic composition, when a first crystal grain 11 is the one in which a Ca content is lower than 2.5 mol% and a second crystal grain 12 is the one in which a Ca content is between 2.5 to 13.5 mol%, the second crystal grain 12 has a cross-sectional area ratio of 30% to 80% on the basis of 100% of an overall cross-sectional area of the fine structure.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、誘電体材料及びこ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、焼結後の微細構造において、Ｃａ含量が２．５ｍｏｌ％未満の結晶粒を第１の結晶粒１１、Ｃａ含量が２．５〜１３．５ｍｏｌ％の結晶粒を第２の結晶粒１２としたとき、上記第２の結晶粒１２の断面積比が全断面積１００％に対して３０％〜８０％である誘電体磁器組成物である。【選択図】図１
