►Description

Synthetic cryolite is also called sodium fluoroaluminate,cryolite ,kryolite,

aluminum sodium fluoride .Synthetic cryolite is the inorganic compound with the

formula Na3AIF6 . This white solid, discovered by theBrazilian José Bonifácio de

Andrada e Silva, occurs naturally as the mineral cryolite and is used extensively in

the industrial production of aluminium metal. The compound consists of the sodium

(Na+) salt of hexafluoroaluminate (AlF63−).Most cryolite is manufactured from

aluminium oxides, hydrofluoric acid, and sodium hydroxide or the equivalent

reagent hexafluorosilicic acid:6 NaOH + Al2O3 + 12 HF → 2 Na3AlF6 + 9 H2OIt

was mined as cryolite at Ivigtût on the west coast of Greenland, until the deposit

was depleted in 1987.Cryolite is poorly soluble in water, which mitigates problems.

The LD50 = 600 mg/kg for the comparable compound aluminium trifluoride.
