Trisodium hexafluoroaluminate Chemical Properties,Uses,Production
Chemical Properties
Sodium aluminum fluoride (Cryolite) is a snow-white crystalline solid, powder or vitreous mass. The crystalline solid (natural product (cryolite) may be colored reddish or brown or even black but loses this discoloration on heating); synthetic product is an amorphous powder. Odorless
Uses
Sodium aluminum hexafluoride is used as a solvent (or flux) for electrolysis aluminum oxides such as bauxite, whitener for enamels and an opacifier for glass and in the industrial production of aluminum.
Definition
A compound found in large quantities in South Greenland. It is white or colorless, but may be reddish or brown because of impurities. Sodium hexafluoroaluminate is used as a flux in the manufacture of aluminum. It crystallizes in the monoclinic system but in forms that closely resemble cubes and isometric octahedrals.
Application
Recycling and treatment of fluorine-containing waste are required for environmental protection and to utilize the fluorine resources. Because of decreases in fluorite reserves and inefficient fluorine resource recovery, cryolite has become a potential resource for fluorine recovery[1].

Flammability and Explosibility
Non flammable
reaction suitability
reagent type: catalyst
core: aluminum
Potential Exposure
Sodium aluminum fluoride (Cryolite) is used in making pesticides, ceramics, glass, and polishes; in refining reduction of aluminum, flux, glass, and enamel.
Shipping
UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.
Incompatibilities
Incompatible with strong acids such as sulfuric, strong oxidizers, hydrogen fluoride.
Waste Disposal
In accordance with 40CFR 165 recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.
