1) Molecular formula: AlF3
2) Molecular weight: 83.89
3) Property: Aluminum fluoride is white powder, density is 2.882, poorly soluble in water, the property is stable, do not react with sulfuric acid if heated, can be broken down by water vapor at 300～400℃ into hydrogen fluoride and aluminium oxide.
4) Usage: To reduce the melting point and increase the electric conductivity of the electrolyte in aluminium electrolysis; it can be used as the flux of enamel glaze, it can also be used as the catalyst in organic synthesis, etc.
5) Technical index: Execute QB/NH 02-2009 standard
