ABSTRACT:
A ceramic-forming composition comprises from 2.0 to 5.0 mol parts of MnO.sub.2 and from 0.05 to 0.30 mol part of Y.sub.2 O.sub.3 based on 100 mol parts of a main component comprising from 50.20 to 53.50 mol % of TiO.sub.2 and from 49.80 to 46.50 mol % of SrO. A semiconductor porcelain substrate, a dielectric porcelain substrate and a capacitor are produced by using the same ceramic-forming composition.
