Aluminum oxide

Aluminum oxide (or alumina) is an inorganic compound primarily used as an abrasive due to its hardness and strength. It is chemically represented as Al₂O₃.

Properties

Aluminum oxide is a white, crystalline powder with a chemical formula of Al₂O₃. It is insoluble in water and organic solvents, and is extremely hard and brittle.

Production

Aluminum oxide is produced from the aluminum metal. The process involves the oxidation of aluminum in the presence of oxygen at high temperatures. This process is known as the Bayer process.

Uses

Aluminum oxide is widely used in the production of aluminum metal. It is also used as an abrasive, in the manufacture of refractory materials, and in a variety of other industrial applications.

Health effects

Exposure to aluminum oxide can cause irritation to the eyes, skin, and respiratory system. It is recommended to use protective equipment when handling this substance.
