Description

Aluminium oxide or aluminum oxide is a chemical compound of aluminium and oxygen with the chemical formula Al₂O₃. It is the most commonly occurring of several aluminium oxides, and specifically identified as aluminium(III) oxide. Wikipedia Formula: Al2O3 Molar mass: 101.96 g/mol Melting point: 2,072 °C Density: 3.95 g/cm³ Boiling point: 2,977 °CAluminium oxide is insoluble in water. In its most commonly occurring crystalline form, called corundum or α-aluminium oxide, its hardness makes it suitable for use as an abrasive and as a component in cutting tools. Aluminium oxide is responsible for the resistance of metallic aluminium to weathering.
