Aluminium oxide (or aluminium(III) 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 oxide. It is commonly called alumina and may also be called aloxide, aloxite, or alundum in various forms and ...

It has a very high surface-area-to-weight ratio, due to the many "tunnel like" pores that it has. Activated alumina in its phase composition can be represented only by metastable forms (gamma-Al 2 O 3 etc.). Corundum (alpha-Al 2 O 3), the only stable form of aluminum oxide, does not have such a chemically active surface and is not used as a ...
Aluminium oxide is an amphoteric oxide of aluminium with the chemical formula Al 2 O 3. It is also commonly referred to as alumina or aloxite [1] in the mining, ceramic and materials science communities. It is produced by the Bayer process from bauxite.
The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer.Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al 2 O 3), the rest being a mixture of silica, various iron oxides, and titanium dioxide.

Because of white fused alumina's hardness (9.0 on the Mohs scale), It is second only to diamond and silicon carbide.It is commonly used as a raw material in abrasive tools, blasting, lapping, polishing, and grinding. white fused alumina is also used in refractories and ceramic shapes laminates due to chemical stability, high melting point, etc.
