SOLID ELECTROLYTE CAPACITOR HAVING METALLIC CATHODE COLLECTOR IN DIRECT CONTACT WITH MANGANESE DIOXIDE ELECTROLYTE AND METHOD OF PRODUCING SAME

摘要

In a solid electrolyte capacitor, a metallic cathode collector layer is in direct contact with an electrolyte layer which is formed of densely accumulated manganese dioside particles of 0.1 - 50 .mu.m. The manganese dioxide layer is formed by performing the pyrolysis of manganese nitrate in a semi-closed heating chamber of a radiant furnace to offer a resistance to the outflow from the chamber of gaseous decomposition products. The collector layer is formed by spraying, preferably by plasma spraying, of a metal powder typified by copper powder.
