1. Mainly used as a modifier and flux in the aluminum electrolysis process.
As a regulator, aluminum fluoride can increase the conductivity of the electrolyte, and aluminum fluoride can be added according to the analysis result to adjust the composition of the electrolyte to maintain a predetermined electrolyte molecular ratio.

As a flux, aluminum fluoride can lower the melting point of alumina, facilitate the electrolysis of alumina, control the heat balance of the electrolysis process, and reduce the energy consumption of the electrolysis process.

2. Used as a catalyst in the synthesis of organic compounds and organofluorine compounds, as a component of ceramics and enamel fluxes and glazes, as a modifier for refractive index of lenses and prisms, for the production of fluorinated glass with low “light loss”in infrared spectrum.

3. Can be used as an inhibitor in alcohol production.
