Product Description

 

White sodium aluminium fluoride CAS NO 15096-52-3 using as

 

solvent (or flux) for electrolysis of aluminium oxides

 

 

 ►Description

     

 

      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.
