PURPOSE:To obtain a highly dielectric ceramic composition having small dielectric loss and high alternative current breakage voltage by adding additives consisting of NiO, CeO2, MnO and SiO2 to a main composition consisting of BaTiO3, Ba2rO3, CaTiO3 and MgTiO3. CONSTITUTION:The dielectric ceramic composition obtained by adding (B) additives (0.05-0.4wt.% NiO, 0.03-0.3wt.% CeO2, 0.03-0.19 MnO and 0.00-0.4wt.% SiO2) to (A) a main composition (41.0-48.0mol% BaTiO3, 9.0-11.0mol% BaZrO3, 32.0-39.0mol% CaTiO3 and 7.0-13.0mol% MgTiO3) and useful for ceramic condenser, laminate condenser, high-frequency condenser, etc. |
