Aluminum Fluoride is a chemical compound with the formula AlF3. It is a white, crystalline solid that is primarily used in the production of aluminum metal through the Hall-Héroult process. This compound helps to lower the melting point of alumina, making the extraction of aluminum more efficient. In addition to its role in aluminum production, Aluminum Fluoride is also used in the manufacture of glass and ceramics. It can improve the properties of these materials, such as their durability and resistance to thermal shock. Furthermore, it has applications in the field of fluoride therapy for dental health.
