摘要： A dielectric ceramic composition is disclosed, comprising as three components lead nickel niobate, lead titanate, and lead magnesium iron tungstate, wherein the composition in terms of the three components is represented by the formulaX[Pb(Ni.sub.1/3 Nb.sub.2/3)O.sub.3 ].Y[PbTiO.sub.3 ].Z[Pb(Mg.sub.1/4 Fe.sub.1/4 W.sub.1/2)O.sub.3 ]wherein X+Y+Z=1.00, X, Y, and Z are within the polyhedral area formed by lines connecting points a (X=0.78, Y=0.20, Z=0.02), b (X=0.50, Y=0.20, Z=0.30), c (X=0.40, Y=0.30, Z=0.30), d (X=0.50, Y=0.40, Z=0.10), and e (X=0.58, Y=0.40, Z=0.02) of an X-Y-Z ternary phase diagram. The composition can be sintered at a relatively low temperature, has a high dielectric constant, and is useful as a material for condensers and electrostriction elements.
