APPLICATIONS
The main application of Sodium hexafluoroaluminate is as a solvent (or flux) for electrolysis of 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 used as that solvent.
Unlike typical solutions, this one requires temperatures approaching 1000 °C to melt.
Sodium hexafluoroaluminate is also used as a pesticide.
Other uses of Sodium hexafluoroaluminate include a whitener for enamels and an opacifier for glass.
Sodium hexafluoroaluminate is used as an electrolyte in the production of aluminum by electrolytic reduction.
Sodium hexafluoroaluminate is used in aluminum producing.
Principally, Sodium hexafluoroaluminate can be used as an electrolyte in production and refining of aluminum.

DESCRIPTION
Sodium hexafluoroaluminate is an inorganic compound with formula Na3AlF6.
Sodium hexafluoroaluminate, which is discovered in 1799 by Peder Christian Abildgaard (1740–1801),occurs naturally as the mineral cryolite and is used extensively in the industrial production of aluminium metal. The compound is the sodium (Na+) salt of the hexafluoroaluminate (AlF63−) ion.
Sodium hexafluoroaluminate is used as a solvent (or flux) for electrolysis aluminum oxides such as bauxite, whitener for enamels and an opacifier for glass and in the industrial production of aluminum.
Furhter, Sodium hexafluoroaluminate is white and solid.
Sodium hexafluoroaluminate or sodium aluminium hexafluoride is the inorganic compound with the formula Na3AlF6.
Sodium hexafluoroaluminate occurs naturally as the mineral cryolite, which is also the more common name for this compound.
Most Sodium hexafluoroaluminate is manufactured by a variety of related pathways.
One route entails combining sodium aluminate and hydrofluoric acid:
Na3Al(OH)6 + 6 HF → Na3AlF6 + 6 H2O
Often the hexafluorosilicic acid, which is recovered from phosphate mining, is the precursor in a two-step process beginning with neutralization with ammonia to give ammonium hexafluorosilicate:
H3AlF6 + 3 NH3 → (NH4)3AlF6
(NH4)3AlF6 + 3 NaOH → Na3AlF6 + 3 NH3 + 3 H2O
The mineral form of Sodium hexafluoroaluminate, which is called cryolite, was mined at Ivigtût on the west coast of Greenland until the deposit was depleted in 1987.
Cryolite is poorly soluble in water.
Sodium hexafluoroaluminate is generally immediately available in most volumes.
High purity, submicron and nanopowder forms of Sodium hexafluoroaluminate may be considered.
Sodium hexafluoroaluminate is a chemical compound of sodium, fluorine, and aluminum that occurs naturally as the mineral cryolite.
