Abstract

PURPOSE: To manufacture Al alloy foil for an electrode of an electrolytic capacitor by forming many deep etching holes in the surface of high purity Al foil contg. a specified amount of P or As at high density by former-stage etching and by making the holes thicker and deeper by latter-stage etching.
CONSTITUTION: Al alloy foil having ≥99.9% Al purity and contg. 0.5W100wt- ppm P or As is subjected to former-stage etching with DC having 5W40A/dm2 current density in an aqueous soln. contg. 2W15% Cl ions and 1W35% hydrochloric acid or sulfuric acid forming a porous oxide film by anodic polarization at 50W100°C. The foil is then subjected to latter-stage etching with DC having 0.5W7A/dm2 current density in an aqueous soln. contg. 2W15% Cl ions and 0.03W3% hydrochloric acid or oxalic acid at 50W100°C.
