Synthetic Cryolite (Na3AlF6, sodium hexafluoroaluminate, sodium aluminium fluoride) is a white crystalline powder manufactured from hydrofluoric acid, sodium carbonate, and aluminium.
Similar term(s): sodium aluminum fluoride, sodium fluoaluminate, sodium fluoroaluminate, sodium hexafluoroaluminate, trisodium hexafluoroaluminate, sodium aluminofluoride, aluminum sodium fluoride, kryolith, kryocide, cryolite, ice spar.
We are engaged in offering a quality approved range of Synthetic Cryolite.
• Stable physical properties
• Safe to use
• Longer shelf life
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.
Synthetic Cryolite is supplied as a dry powder in 25kg paper sacks.
