PURPOSE:To provide high Q value, high dielectric constant, and high insulation resistance and to improve sintering characteristics by adding MnO, Pd5Ge3O11, and Nb2O5 as accessory components to principal components consisting of BaO, TiO2, and NdO3/2. CONSTITUTION:A dielectric porcelain composition for temp. compensation is constituted by adding and incorporating, as accessory components, 0-0.3%, by weight, MnO, 2-20.0% Pb5Ge3O11, and 0.3-10.0% Nb2O5 to principal components which consist of, by mol, 1.0.15.0% BaO, 50.0-67.5% TiO2, and 20.0-47.5% NdO3/2 and in which the total amount of the above components are regulated to 100 parts. By using this composition, the porcelain composition having superior characteristics even if burned at a temp. lower by 140-400 deg.C than the conventional burning temp. is obtained. |
