Anhydrous Aluminium Fluoride

Molecular Formula:anhydrous AlF3

Molecular Weight:83.97

CAS No.:7784-18-1

The anhydrous AlF3 is an off-white, free-flowing granular material,  insoluble in most organic and inorganic liquids at room temperatures. It  is slightly soluble in water (0.56 g/100 ml), The chemical property is  very steady.

Applications:  it can lower the smelting temperature, increase electricity  conductivity and adjust the molecular ratio during aluminum  electrolyzing. It is propitious to the aluminum oxide electrolyte and  reduces the energy consumption during the smelting.  It essentially  lowers the melting points and increase the conductivity of electrolyte,  reducing the electric power consumption. It is also used as the flux of  the non-iron metal etc.   The anhydrous AlF3 supplied by DFD has the advantages such as high  purity, low moisture and high bulk density, which can reduce  environmental pollution, energy consumption and waste emission during  aluminium smelting. Anhydrous AlF3 is the upgrade product of fluoride  for primary aluminium industry.   Spec. :
