High dielectric ceramic capacitor composition

Abstract

There is disclosed a high dielectric ceramic composition for capacitors, which comprises (1-x)Pb(Fe.sub.1/2 Ta.sub.1/2)O.sub.3 xPb(Fe.sub.1/2 Nb.sub.1/2)O.sub.3 wherein 0.35.ltoreq.x.ltoreq.0.65, and 0.01-0.5 % by weight of manganese, chromium or cobalt. The composition can be sintered at a temperature of 1,000.degree. C. with a high dielectric constant and a low dielectric loss coefficient.
