PURPOSE:To provide a composition for a ceramic board, which can be baked at an extremely low temperature, in which the paste of Au, Ag, etc., can be used as an internal electrode, which satisfies various required characteristics such as volume specific resistivity, a dielectric constant, a dielectric loss tangent, breakdown strength, etc., and in which the rate of change of electrostatic capaci tance to a temperature change can be adjusted as + or -0 to + or -100ppm/ deg.C, in the composition for the ceramic board used for manufacturing various multilayer interconnection boards. CONSTITUTION:The title composition is composed of 60-95wt.% glass frit and 40-5wt.% titanate, said titanate consists of SrTiO3, CaTiO3, etc., or the solid solution, etc., of these titanate, and said glass frit is made up of 30-40wt.% SiO2, 10-20wt.% Al2O3, 5-20wt.% CaO+MgO, 5-15wt.% ZnO, 10-20wt.% TiO2, 0.5-2wt.% B2O3 and 0.2-1wt.% ZrO2. |
