Abstract
Low temperature fired dielectric ceramic compositions are prepared by firing, at temperatures between about 1000.degree. C. and about 1150.degree. C., a base ceramic preparation comprising barium titanate, strontium titanate, barium zirconate, titanium dioxide and manganese dioxide mixed with a glass frit comprising zinc oxide, silicon dioxide, boron oxide, lead oxide, bismuth tioxide, and cadmium oxide. The resulting dielectric ceramic composition is useful to form multilayer ceramic capacitors.
