ABSTRACT:
A method for manufacturing ceramic capacitors of the lead filled type comprises coating the end surfaces of a ceramic monolith having internal voids opening to the ends with a termination paste. The paste includes glass frit, a metal component wettable by lead, i.e. silver, binder and solvent, the characterizing feature of the paste being the inclusion of reducible metal salts of a metal wettable by lead, the salts undergoing volumetric diminution when reduced from the salt to the metallic state. When the termination paste is sintered, reduction of the metallic salt provides the termination with a porous latticework. Molten lead or lead alloys are injected through the now porous, sintered termination paste. The disclosure further relates to a capacitor made in accordance with the method described.
