Chemische Eigenschaften
Sodium aluminum fluoride 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
Verwenden
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.
m?gliche Exposition
Sodium aluminum fluoride is used in making pesticides, ceramics, glass, and polishes; in refining reduction of aluminum, flux, glass, and enamel.
