Na3AlF6 Fluxing agent/active filler aluminium sodium fluoride
Product Name: Sodium Fluoroaluminate / Synthetic Cryolite
CAS No.:159096-52-3
MF:Na3AlF6
MW:209.94
EINECS:239-148-8
Mol File:159096-52-3mol
Product Description:
Cryolite and six fluoride and sodium aluminate and sodium aluminum fluoride, formula for Na3AlF6, white tiny crystals, no smell, solubility, larger than the natural cryolite ratio is 3, 2 ~ 3 hardness, melting point 1009 ℃, easy water be affected with damp be affected with damp.
Cryolite is mainly used as fluxing agent in the production of aluminum electrolysis, rubber, wheel wear resistant filler, enamel opal agent, glass of sunscreen and metal flux, crops insecticide, etc.
Hall - Heroult method is to use cryolite based fluoride as solvent to produce aluminium melt method, so far haven't found another compounds can take the place of cryolite.This is because the cryolite besides can dissolve the alumina also has some other indispensable properties, such as excluding than aluminum correction electrical elements, good stability, under the condition of the general decomposition, non-volatile, deliquescence, melting point higher than that of aluminum, good conductivity, electricity saving, etc.
