Chemical Formula Li₃AlF₆

Molecular Weight 209.94 g/mol

Lithium cryolite (Li3AlF6) is a synthetic, plays a crucial role in the production of aluminum. It is used primarily in the electrolytic process of extracting aluminum from bauxite, where it acts as a flux to lower the melting point of alumina (Al2O3), thus improving the efficiency of the electrolysis process. This reduces energy consumption and enhances the overall effectiveness of aluminum refining.

Industrial Uses

1. Metal Treatment

  • Aluminum Smelting: Lithium cryolite is widely used in the metallurgical industry, especially in the aluminum industry. It serves as a fluxing agent in the Hall-Héroult process, which is the primary method for aluminum extraction. Lithium cryolite reduces the melting point of aluminum oxide (Al₂O₃), facilitating the separation of aluminum metal during smelting and improving the efficiency of the process.

2. Chemical Synthesis

  • Fluoride Source for Chemical Reactions: Lithium cryolite can serve as a source of fluoride ions in the synthesis of fluorinated organic compounds, including those for specialized chemical applications or fluoropolymer synthesis.
