ABSTRACT:
A ceramic glass material comprising a mixture of fine particles of barium titanate, leaded glass frit and an additive material containing manganese. A ceramic glass body and capacitor made from the material by firing the ceramic glass material to a peak temperature between 900.degree. C. and 1050.degree. C. in a non oxidizing atmosphere at which the glass softens. The capacitor has non precious metal electrodes with a melting point above the firing temperature which are co-fired with the ceramic glass material. Upon cooling the fired ceramic glass material and electrodes form a capacitor with the ceramic glass body separating the electrodes and providing a high dielectric constant and insulation resistance, and a low dissipation factor.
