Abstract
A temperature compensating ceramic dielectric of the present invention contains compositions consisting of 2.0 to 14.0 mole % of barium oxide, 51.0 to 63.5 mole % of titanium oxide and 22.5 to 47.0 mole % of neodymium oxide as NdO.sub.3/2. Among the composition range, however, ranges between 2.0 to 9.0 mole % of barium oxide and 60.0 to 63.5 mole % of titanium oxide are to be excluded. By adding 0.1 to 5.0% by weight of niobium oxide as NbO.sub.5/2 to the composition, the temperature compensating ceramic dielectric is obtained.
