Abstract
A process for manufacturing a dielectric member from aluminum or aluminum alloy which includes the steps of subjecting the aluminum or aluminum alloy to anodic oxidation in a nonaqueous electrolytic solution containing an organic solvent and dehydrated boric acid to form an oxide layer thereon, and buffing the oxide layer with a composition containing insulative abrasive grains and insulative binding material.
