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. :
