    Reliable Sodium Aluminum Fluoride 209.94 Molecular Weight 98% Purity


    Cryolite powder CAS NO 15096-52-3 worked as solvent (or flux) for

    electrolysis of aluminium oxides


    ►Description

    1. Cryolite is one kind of odorless white solid or powder. The IUPAC Name of this chemical is

    trisodium;hexafluoroaluminum(3-). This chemical belongs to the product categories which is

    inorganics. It’s slightly soluble in water, but insoluble in anhydrous hydrogen fluoride.


    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.

    ►Application

    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.
