A high purity etched aluminum foil is anodized in a boric acid-ammonium water type solution, for exsample, to form an aluminum oxide film on its surface. This aluminum oxide film is what we call the dielectric of the aluminum electrolytic capacitor. The DC voltage that is applied to the foil to oxidize the anode foil is called \"Forming
