Abstract

PURPOSE: To obtain granular Al powder formed oxidation film on the surface, by forming Al powder under pressure in the state of burying the electrode in Al powder and crushing the above formed body after electrolyzing the obtained formed body as anode in an electrolytic bath.
CONSTITUTION: After forming Al powder under pressure in the state of sandwiching between foil-like, net-like, etc. Al electrode, the obtained formed body is dipped in the electrolytic bath and anodic oxidation treatment is carried out by usual method connecting the above electrode with anode side of power source. On this occasion, the following condition is preferable. That is, grain diameter of Al powder; 43W279μm. forming pressure; 100W1,000kg/cm2, forming thickness; about 2W 5mm. Granular Al powder covered by oxidation film being its surface of uniform thickness, is obtained by crushing the formed body with ball mill, etc. after carrying out anodic oxidation.
