ABSTRACT:
Ceramic dielectric compositions for temperature compensating capacitors, exhibiting a high dielectric constant, a relatively small temperature coefficient of dielectric constant and a very excellent linearity of the temperature coefficient, comprising 1.2-19.0% by weight of SrO, 12.2-17.4% by weight of CaO, 35.8-43.9% by weight of TiO.sub.2, 15.7-37.6% by weight of Bi.sub.2 O.sub.3, 1.9-14.6% by weight of Pb.sub.3 O.sub.4 and 0.9-2.7% by weight of MgO.
