METHOD FOR PRODUCING ELECTROLYTIC CAPACITORS FROM VALVE METAL POWDERS.

摘要

The invention relates to a method for producing an anode for electrolytic capacitors, wherein the method comprises the following steps: a.) pressing a tantalum powder around a tantalum wire or a tantalum band or a tantalum sheet in order to form a compact; b.) sintering the compact in order to form a porous sintered body; c.) cooling the sintered body; d.) treating the porous sintered body with one or more gaseous or liquid oxidants; and e.) anodically oxidizing the treated sintered body in an electrolyte in order to form a dielectric layer.
