ABSTRACT:
A dielectric ceramic composition comprising 87.5 to 99.6 mole % of barium titanate as a first component, 0.2 to 7.0 mole % of copper oxide as a second component, 0.2 to 5.5 mole % of at least one member selected from the group consisting of lithium oxide, zinc oxide, cadmium oxide and iron oxide as a third component, and if necessary, at least one complex oxide selected from the group consisting of lead titanate, strontium titanate, calcium titanate, magnesium titanate, barium zirconate, calcium zirconate, strontium zirconate, lead zirconate, magnesium zirconate, lead stannate, calcium stannate, strontium stannate, barium stannate and magnesium stannate, as a fourth component in an amount of 0.3 to 40.0 moles per 100 moles of the sum of the first, second and third components; and a process for producing said dielectric ceramic composition.
