Sodium Aluminium Fluoride Alf3 Mineral Fluorspar Power In Chemical

Specifications:

Description:

Aluminium fluoride(AlF3) is an inorganic compound used primarily in the production of aluminium. This colourless solid can be prepared synthetically but also occurs in nature.

Aluminium fluoride is an important additive for the production of aluminium by electrolysis. Together with cryolite lowers the melting point to below 1000 °C and increases the conductivity of the solution. It is into this molten salt that aluminium oxide is dissolved and then electrolyzed to give bulk Al metal

Applications:

Aluminium fluoride is primarily used in the production of aluminium. It is a critical additive to the molten electrolyte in aluminium metal production. Using today\'s technologies, it is impossible to manufacture aluminium without AIF3. Adding AIF3 allows the electrolytic process to take place at a temperature around 850°C, which is considerably lower than the melting point for aluminium oxide (Al2O3, mp ab. 1,500°C). As a result of its temperature-lowering properties, AlF3 has a definite energy saving effect.
