Medical Definition of ALUMINA. : an oxide of aluminum Al2O3 that occurs native as corundum and in hydrated forms (as in bauxite) and is used in antacidsâcalled also aluminum oxide.
Aluminium oxide is responsible for the resistance of metallic aluminium to weathering. Metallic aluminium is very reactive with atmospheric oxygen, and a thin passivation layer of aluminium oxide (4 nm thickness) forms on any exposed aluminium surface. This layer protects the metal from further oxidation.luminium oxide is a chemical compound of aluminium and oxygen with the chemical formula Al 2 O 3. It is the most commonly occurring of several aluminium oxides, and specifically identified as aluminium(III) oxide.
