Sodium aluminium hexafluoride is the inorganic compound with the formula Na₃AlF₆. This white solid occurs naturally as the mineral cryolite and is used extensively in the industrial production of aluminium metal. 

Detailed description

The compound consists of the sodium (Na⁺) salt of hexafluoroaluminate (AlF₆³⁻).

Use

The main application of synthetic cryolite is as a solvent (or flux) for electrolysis aluminium oxides such as bauxite. The conversion of aluminium oxides into metallic aluminium requires that the metal ions be dissolved so that they can accept the electrons provided in the electrolysis cell. A mixture of cryolite and some aluminium trifluoride is that solvent. Unlike typical solutions, this one requires temperatures approaching 1000 °C to melt. Sodium aluminium hexafluoride is also used as a pesticide. Other uses include a whitener for enamels and an opacifier for glass.
