Al2O3 is an electrical insulator but has a relatively high thermal conductivity (30 Wm−1K−1[1]) for a ceramic material. Aluminum oxide is completely insoluble in water. In its most commonly occurring crystalline form, called corundum or α-aluminum oxide, its hardness makes it suitable for use as an abrasive and as a component in cutting tools.

Aluminum oxide is responsible for the resistance of metallic aluminum to weathering. Metallic aluminum is very reactive with atmospheric oxygen, and a thin passivation layer of aluminum oxide (4 nm thickness) forms on any exposed aluminum surface. This layer protects the metal from further oxidation. The thickness and properties of this oxide layer can be enhanced using a process called anodizing. A number of alloys, such as aluminum bronzes, exploit this property by including a proportion of aluminum in the alloy to enhance corrosion resistance. The aluminum oxide generated by anodizing is typically amorphous, but discharge assisted oxidation processes such as plasma electrolytic oxidation result in a significant proportion of crystalline aluminum oxide in the coating, enhancing its hardness.

Applications: Filler, Catalysis, Purification, Abrasive, Paint, electrical insulator

The great majority of aluminum oxide is consumed for the production of aluminum, usually by the Hall process.

Using a plasma spray process and mixed with titania, it is coated onto the braking surface of some aluminium bicycle rims to provide abrasion and wear resistance
