ABSTRACT:
In the production of low voltage aluminum foil capacitor electrodes, etched and clean foil is subjected to a thermal treatment at about 595.degree. to 650.degree. C. and then anodized in an adipate formation electrolyte. The electrolyte may contain a minor amount of a phosphate salt, or the final reanodization may be carried out in a phosphate electrolyte.
