Glass material and method for manufacturing same
Provided is a glass composition that exhibits greater Faraday effect than ever before. A glass composition contains 48% or more of Tb.sub.2O.sub.3 (exclusive of 48%) in % by mole.
OPTICAL GLASS AND OPTICAL ELEMENT
The invention provides a high-refraction low-dispersion optical glass with refractive index of 1.76-1.80 and Abbe number of 47-51. The optical glass, comprising the following components by weight percentage: 0-3% of SiO.sub.2; 25-40% of B.sub.2O.sub.3; 20-40% of La.sub.2O.sub.3; 12-25% of Gd.sub.2O.sub.3; 6.5-15% of ZrO.sub.2; greater than 10% but less than or equal to 20% of ZnO; 0-5% of Ta.sub.2O.sub.5; 0-5% of Nb.sub.2O.sub.5; 0-10% of Li.sub.2O; less than 0.45 of (Ta.sub.2O.sub.5+Nb.sub.2O.sub.5)/(ZnO+Li.sub.2O); 0-10% of Y.sub.2O.sub.3; and below 625 C. of glass transition temperature Tg. With reasonable component ratio, the high-refraction low-dispersion optical glass favorable to precision is molding with excellent transmittance can be easily enabled while realizing the required optical constant of the glass of the present invention.

VARISTOR COMPOSITION AND MULTILAYER VARISTOR
A varistor composition free of Sb comprising: (a) ZnO; (b) BBiZnPr glass, or BBiZnLa glass, or a mixture thereof; (c) a cobalt compound, a chromium compound, a nickel compound, a manganese compound, or mixtures thereof; (d) SnO.sub.2; and (e) an aluminum compound, a silver compound, or a mixture thereof. By adjusting the ratio between the components, the varistor composition may be made into a multilayer varistor with inner electrodes having a low concentration of noble metals at a sintering temperature less than 1200 C. The multilayer varistor made from the varistor composition has good maximum surge current, good ESD withstand ability, and low fabrication cost.
