2. Cryolite is the inorganic compound with the formula Na3AIF6 . This white solid,
discovered by the Brazilian 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−).
3. 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 H2O
It was mined as cryolite at Ivigtût on the west coast of Greenland, until the deposit
was depleted in 1987.
4.Cryolite is poorly soluble in water, which mitigates problems. The LD50 = 600
mg/kg for the comparable compound aluminium trifluoride.

1. The main application of synthetic cryolite 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 that solvent. Unlike typical solutions, this one requires
temperatures approaching 1000 °C to melt.
2.cryolite is also used as a pesticide.
