"Oxidizing aluminum without electricity?"



2000

Does anybody know of any chemicals or solutions which can oxidize aluminum WITHOUT using electricity (i.e. anodizing)?

Could you just heat it in air or oxygen? What thickness are you expecting?

Aluminium oxidizes very quickly, but its oxidized form makes a new coating that protects it from further oxidation. Rubbing mercury on the aluminum should allow more of it to oxidize.

In the October 2004 issue of Popular Science they have an article on the oxidization of Aluminum. You may find this to help you immensely.

I have been using a mixture of KOH + H2O (Potassium hydroxide and water) to oxidize aluminum to create hydrogen gas for experiments for some time. Sodium hydroxide can be used as a replacement for the KOH, but the KOH is more cost effective.

Both chemicals are highly corrosive. Beware!
Good Luck
