aluminum oxide

Aluminum oxide, also known as alumina, is a chemical compound made up of aluminum and oxygen. It appears as a white, odorless powder and is commonly found in nature as the mineral corundum. Aluminum oxide is widely used in various applications, including the production of aluminum metal, as an abrasive material, and in ceramics. It also serves as an important component in catalysts and is used in some types of dental products. Its hardness and resistance to corrosion make it valuable in industrial settings, while its transparent form is used in safes and protective coatings.
