Abstract
A high dielectric porcelain composition having, as a main component, a Pb(Mg 1/3, Nb 2/3)O.sub.3 -PbTiO.sub.3 -Pb(Mn 1/3, Nb 2/3)O.sub.3 system including 95 mol. % of Pb(Mg 1/3, Nb 2/3)O.sub.3, 5 mol. % of PbTiO.sub.3 and 0.5 weight % of Pb(Mn 1/3, Nb 2/3)O.sub.3, and, in addition, a sub-component including PbO and ZnO. Such a dielectric porcelain is capable of being sintered at a temperature lower than 1000.degree. C. A method of reducing the sintering temperature of such a high dielectric porcelain composition, is also provided.
