    98% Sodium Aluminum Fluoride White Powder UN NO 3077 13.8% Al 31.2 Na

    98% Na3AlF6 Sodium aluminium fluoride powder UN NO 3077 used as opacifier for

    glass and pesticide in agriculture


    ►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.
