Abstract
PURPOSE:To obtain a porcelain of dielectric material having a negative and large coefficient of temperature and large specific dielectric constant, by limiting a range of component composition of PbO, ZrO2 and Tm2O3. CONSTITUTION:A porcelain composition which consists of lead oxide (PbO), zirconium dioxide (ZrO2) and thulium trioxide (Tm2O3), has a composition formula shown by the formula and coefficients X, Y and Z of atomic groups showing the composition in the molar ratio of 0.46<=X<=0.52, 0.46<=Y<=0.52, 0.002<=Z<=0.04 and X+Y+Z=1. The porcelain composition is constituted by blending lead oxide with zirconium dioxide and thulium trioxide in a given composition range and calcining. The combination of the porcelain composition of dielectric material with a porcelain composition having a positive and large temperature coefficient and large specific dielectric constant can provide a porcelain composition of dielectric material having large specific dielectric constant and a temperature coefficient close to 0(ppm/ deg.C) and provide electric parts of minimized type having excellent temperature characteristics.
