Aluminum fluoride is a white, crystalline compound that is commonly used as a flux in the aluminum industry. It is used to lower the melting point of alumina, which is the raw material for aluminum production, and to increase the electrical conductivity of the molten aluminum.

In addition to its application as a flux, aluminum fluoride is also used as a catalyst in the production of certain types of aluminum alloys, such as those used in aerospace applications. It is also used as a coating on ceramic and glass materials to increase their resistance to wear and corrosion.

Aluminum fluoride has also found applications in other industries, such as the production of pharmaceuticals, where it is used as an intermediate in the synthesis of various compounds. It is also used in the production of nanomaterials and as a stimulant for the immune system in various vaccine formulations. Furthermore, this compound is used as an additive in dental pastes and as a tooth protector against decay in dentistry.

Given the various applications of aluminum fluoride, this compound is considered one of the important and vital materials in the aluminum industry and related industries. However, due to the hazards that this compound poses to human health and the environment, its use must be handled with caution.
