Abstract
A nonreducible dielectric ceramic composition of a system, (A.sub.1-x R.sub.x).sub.y BO.sub.3, is prepared by preparing a slurry containing at least one compound selected from the group consisting of carbonates and hydroxides of Ba, Sr, Ca and Mg, at least one compound selected from the group consisting of carbonates and hydroxides of rare earth elements R, and at least one compound selected from the group consisting of oxides, carbonates and hydroxides of Ti, Zr and Sn; filtering the resulting slurry; washing the filter cake with water and calcining the resulting washed cake.
