Abstract:
    A high dielectric porcelain composition having, as a main component, a Pb(Mg 1/3, Nb 2/3)O3-PbTiO3-Pb(Mn 1/3, Nb 2/3)O3 system including 95 mol. % of Pb(Mg 1/3, Nb 2/3)O3, 5 mol. % of PbTiO3 and 0.5 weight % of Pb(Mn 1/3, Nb 2/3)O3, 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 DEG C. A method of reducing the sintering temperature of such a high dielectric porcelain composition, is also provided.
