Synthetic cryolite is a white crystalline powder manufactured from hydrofluoric acid, sodium carbonate, and aluminium. Synthetic cryolite is used chiefly as a flux in the electrolytic production of aluminum as it effectively lowers down the melting point of alumina. It is used in the glass and enamel industries, in bonded abrasives as a filler, in making salts of sodium and aluminum and porcelaneous glass and in the manufacture of insecticides. Cryolite is a relatively safe fruit and vegetable insecticide. The fluoride ion inhibits many enzymes that contain iron, calcium, and magnesium.
| Molecular Formula | Na3AlF6 | Molecular Weight | 209.94 | ||||
|
Properties |
It is a colorless monoclinic crystal, but often appears off-white, pompadour, straw yellow or black due to impurities. It has relative density of 2.9-3.0, mp 1000. It is slightly soluble in water, and its aqueous is acidic. It decomposes to release poisonous HF gas while meeting sulfuric acid. | ||||||
|
Usages |
It is used as flux in aluminum smelting, cropper insecticide, flux and whiting agent of enamel glaze. It is also used in the manufacture of milky white glass, aluminum alloy and boiling steel. Its used as ingredient of grinding wheel. | ||||||
