Abstract:
A dielectric ceramic composition for a microwave device including MgTiO.sub.3 and CaTiO.sub.3 as a main component and a Li.sub.2 Co.sub.3 as a sub-component, said composition being sintered at a temperature of 1100 to 1250.degree. C., and said composition being expressed as follows:(Composition equation)(94MgTiO.sub.3 -6CaTiO.sub.3)+xLi.sub.2 CO.sub.3 (Mol %)wherein x lies within a range of 0.2.ltoreq.x.ltoreq.0.4 (mol %), and Li.sub.2 CO.sub.3 of x mole % is added in excess to the main composition.
