ABSTRACT:
A glass casing for a capacitor includes a lead wire at one closed end which is filled with aluminum powder. A hollow porous tubule is inserted into the powder which is sintered, with the glass mold withstanding the sintering. The mold and sintered body are immersed in an electrolyte with the lead wire connected as the anode to form the dielectric oxide layer. The oxide layer forming solution is removed and a manganizing solution penetrates through the tubule and sintered body. Another lead is inserted through the tubule and joined to the manganese layer. Resin may be poured into the open mold and the glass fused at the open end.
