A chemical compound of aluminum and oxygen, aluminum oxide (Al2O3) is an odorless white solid. The most common of the aluminum oxides, it is alternatively called alumina, aloxide, aloxite, alundum or aluminum(III) oxide, with the naming convention often depending on the form, application, or industry being discussed.
Applications
Over 90% of all aluminum oxide goes into the production of aluminum metal. The remainder goes on to be used in countless applications across nearly every industry, from cutting-edge energy storage technology to cosmetics. Common applications include:
- Glass and ceramic production. A common ingredient in a number of standard glass and ceramic formulas.
- Catalysis. Used for a number of commercially or academically valuable chemical reactions.
- Water purification. Commonly used for the extraction of water from gas streams.
- Pigment production. Popular for the ‘alumina effect’ in pigments.
- Abrasion and abrasion protection. Hardness lends itself to abrasive applications and to protective coatings against abrasion.
- Refractory applications. A high melting point makes aluminum oxide a popular refractory material.
- Composites. Part of research into high-performance composite fibers, including alumina nanofibers.
