ABSTRACT:
A method for making an electrolytic capacitor. A valve metal powder of the sponge type is compressed into a compact body and other usual steps including anodization and electrode application are carried out thereon. Mainly due to the use of sponge type valve metal powder, this method makes it unnecessary to carry out the conventionally employed step of sintering the compact body and produces an electrolytic capacitor having properties better than those obtained by the conventional method. This invention also provides an electrolytic capacitor characterized by the use of sponge type valve metal powder and specific lubricant materials.
