98% Min Industry Na3alf6 Powder , Wear Resistant Filler Sodium Hexafluoroaluminate

98% Industry uses of synthetic cryolite powder is as wear-

resistant filler and fluxing agent


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.
