发明名称 Dielectric ceramic composition and laminated ceramic capacitor using the same
摘要 Provided is a highly reliable laminated ceramic capacitor in which decrease of dielectric constant under a high electric field is small and which satisfies the B-grade and X7R grade characteristics, using Ni for the inner electrodes, wherein the dielectric material contains about 0.2 to 5.0 parts by weight of Li2O-(Si, Ti)2-MO oxides (MO is at least one of the compounds of Al2O3 and ZrO2) or SiO2-TiO2-XO oxides (XO is at least one of the compounds of BaO, CaO, SrO, MgO, ZnO and MnO) relative to 100 parts by weight of a principal component represented by (Ba1-xCaxO)mTiO2+alphaRe2O3+betaMgO+gammaMnO (Re2O3 represents at least one of Y2O3, Gd2O3, Tb2O3, Dy2O3, Ho2O3, Er2O3 and Yb2O3).
