| 简介 |
A dielectric ceramic composition according to the present invention contains a substance represented by general formula 100 (Ba 1-x Ca x ) m TiO 3 + aMnO + bCuO + cRO n (wherein the coefficients 100, a, b, and c each represent a molar ratio; R represents at least one element selected from the group consisting of Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu; and n represents a number determined by the valence of the rare-earth element R and is a positive number required for maintaining electroneutrality) and a sintering aid. The dielectric ceramic composition satisfies the relationships 0.990 ‰ m ‰ 1.050; 0.01 ‰ x ‰ 0.20; 0.5 ‰ a ‰ 3.5; 0.1 ‰ b ‰ 5.0; and 10 ‰ c ‰ 20, and the amount of the sintering aid represented by d in terms of parts by weight satisfies 0.8 ‰ d ‰ 5.0 with respect to 100 parts by weight of the compound represented by (Ba 1-x Ca x ) m TiO 3 . Furthermore, VO 3/2 may be added to increase the breakdown field. |
