CAS 13775-52-5

Chemical Formula K3AlF6

Molecular Weight 212.0 g/mol

Potassium cryolite is a rare, naturally occurring mineral composed mainly of potassium, sodium, aluminum, and fluoride. It has been historically used in the aluminum industry for its ability to lower the melting point of alumina, making it easier to extract aluminum metal. It appears as a white or colorless crystalline substance, and its primary application is in aluminum refining. Additionally, it has been used in certain applications like ceramics and as a fluxing agent in metallurgy.

Industrial Uses

1. Construction

  • Flux in Metal Processing: Potassium cryolite is used as a fluxing agent in the aluminum production process. It reduces the melting point of aluminum oxide (bauxite) during the extraction of aluminum, enabling more efficient metal refining. However, it has limited use in construction beyond its role in the aluminum industry.

2. Metal Treatment

  • Aluminum Production: Potassium cryolite is most commonly used in the metal treatment industry, particularly in the production of aluminum. It acts as a flux during the electrolytic extraction of aluminum from its ores (bauxite). This process is known as the Hall-Héroult process, and potassium cryolite helps lower the temperature at which aluminum oxide melts, improving energy efficiency.

3. Chemical Synthesis

  • Fluorine Source: Potassium cryolite can be used as a source of fluorine in various chemical processes, particularly in the production of fluorinated chemicals. It might be used in the synthesis of aluminum fluoride and other fluorine compounds, which are critical for a range of industrial applications, including specialty chemicals.
