Abstract
This invention is directed to provide a non-reduced dielectric ceramic composition, which comprises a main component comprising BaTiO.sub.3, at least one rare earth metal oxide (Re.sub.2 O.sub.3) selected from the group consisting of Tb.sub.2 O.sub.3, Dy.sub.2 O.sub.3, Ho.sub.2 O.sub.3, and Er.sub.2 O.sub.3, and Co.sub.2 O.sub.3, where such constituents are contained at a predetermined formulation in the main component, an sub-component comprising BaO, MnO, MgO, and at least one compound selected from the group of NiO and Al.sub.2 O.sub.3, and an oxide glass mainly containing Li.sub.2 O--(Si.sub.x Ti.sub.1-x)O.sub.2 --M wherein M represents at least one member selected from the group consisting of Al.sub.2 O.sub.3 and ZrO.sub.2, wherein the main component, the sub-component, and the oxide glass are contained in described amounts. The composition is used as dielectric materials, such as monolithic ceramic capacitors, using base metals such as nickel as an internal electrode material.
