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−).Most Sodium aluminum fluoride 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.Sodium aluminum fluoride 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.
