摘要： A Ni--Zn base ferrite is provided with a relatively small dielectric loss (tan.delta.(.epsilon.)) of the order of 10.sup.-3. Its saturation magnetization (4.pi.Ms) is relatively still high. A Ni--Zn base ferrite having a small dielectric loss (of the order of 10.sup.-3) can be obtained by proportioning raw materials to give a finished composition range of Ni.sub.X Zn.sub.1-X Fe.sub.2-Y-Z Mn.sub.Y M.sub.Z O.sub.4 where M: Ge and/or Sn, 0.55.ltoreq.X.ltoreq.1.00, 0.001.ltoreq.Y.ltoreq.0.36, and 0.002.ltoreq.Z.ltoreq.0.36, by calcination.

摘要： A ceramic composition is herein disclosed, which is a lead-type perovskite compound capable of being subjected to low temperature-sintering among ceramic compositions for use in making capacitors, which has a high dielectric constant at room temperature of not less than 10000, a low temperature-dependency of the dielectric constant and a low decrease in capacitance upon application of a DC bias and which comprises, as a main constituent, a ternary system comprising lead magnesium niobate: [Pb(Mg.sub.1/3 Nb.sub.2/3)O.sub.3 ], lead nickel niobate: [Pb(Ni.sub.1/3 Nb.sub.2/3)O.sub.3 ] and lead titanate: [PbTiO.sub.3 ] in which part of the Pb.sup.2+ ions present in the ternary system are substituted with a desired amount of Sr.sup.2+ ions, Ba.sup.2+ ions or Ca.sup.2+ ions.
