ABSTRACT:
A composition for ceramic dielectrics comprising BaO, CeO.sub.2, ZrO.sub.2, CaO and TiO.sub.2 in sintered state. The composition can also contain at least one of MnO.sub.2, Cr.sub.2 O.sub.3, FeO, NiO, and CoO as additive. As the composition is very fine in grain size, and has a prolonged life, it is very suitable for a raw material of such a product as a layer-built capacitor which is used in high electric field.
