- 24 - HIGH DIELECTRIC CONSTANT TYPE CERAMIC COMPOSITION ABSTRACT OF THE DISCLOSURE A novel ceramic composition exhibiting a solid solution structure of Pb(Fe2/3Wl/3)O3-Pb(ZrO3),can be sintered at a low sintering temperature; have a high insulation resistance; have a relatively high dielectric constant in the high dielectric type ceramic dielectrics; have a low dependence of dielectric constant upon temper- ature, and; have a low dielectric loss. A particular amount of the additives, i.e., MnO, Pb(Mn1/3Nb2/3)O3, Pb(Mn1/2W1/2)O3, Pb(Mn2/3W1/3)O3, Pb(Mn1/3Ta2/3)O3, Cr2O3 and CeO2, is added into the composition mentioned above.
