16 Facts About Aluminium oxide

Aluminium oxide is a chemical compound of aluminium and oxygen with the chemical formula.

Aluminium oxide is responsible for the resistance of metallic aluminium to weathering.

The aluminium oxide generated by anodising is typically amorphous, but discharge assisted oxidation processes such as plasma electrolytic oxidation result in a significant proportion of crystalline aluminium oxide in the coating, enhancing its hardness.

Aluminium oxide was taken off the United States Environmental Protection Agency's chemicals lists in 1988.

Aluminium oxide is on the EPA's Toxics Release Inventory list if it is a fibrous form.
