Production of aluminum foil capacitor electrodes

摘要

In the production of low voltage aluminum foil capacitor electrodes, etched and clean foil is subjected to a thermal treatment at about 595 DEG to 650 DEG 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.
