PURPOSE:To improve a high-temperature characteristic by adding niobium oxide to a composition consisting of barium oxide, titanium oxide, and neodymium oxide. CONSTITUTION:Niobium oxide as NdO5/2 of 0.1-5.0wt.% is added to a composition consisting of barium oxide of 2.0-14.0mol%, titanium oxide of 51.0-63.5 mol%, and neodymium oxide as NdO3/2 of 22.5-47.0mol% (excepting a range of barium oxide of 2.0-9.0mol% and titanium oxide of 60.0-63.5mol% in the above composition range). This obtains a porcelain dielectric for temperature compensation having high insulation resistance, dielectric constant, and Q, the low temperature coefficient of the dielectric constant, and insulation resistance difficult to deteriorate even using at high temperature. |
