摘要：
A ceramic dielectric composition of a ternary system Pb(Mg.sub.1/3 Nb.sub.2/3)O.sub.3 -Pb(Zn.sub.1/3 Nb.sub.2/3)O.sub.3 -PbTiO.sub.3, comprising 69.05-69.60% by weight of Pb.sub.3 O.sub.4, 2.41-4.00% by weight of MgO, 0.08-3.15% by weight of ZnO, 24.01-26.66% by weight of Nb.sub.2 O.sub.5 and 0.13-2.59% by weight of TiO.sub.2. The composition can be sintered at a low firing temperature less than 1,150.degree. C., and has a high dielectric constant above 10,000.
