What else can cryolite do besides lowering the melting point of alumina?

As we all know, the important role of cryolite in aluminum smelting is to lower the melting point of alumina. What else can it do? Next, let's take a look at the analysis of cryolite manufacturers.

   1. Pure cryolite does not contain metal impurities whose precipitation points are more accurate than aluminum. As long as no impurities are brought in from the outside, electrolytic production can obtain purer aluminum.

   2. Cryolite can dissolve alumina well. When the electrolysis temperature is 1,000 degrees Celsius, the solubility of alumina in cryolite solution is generally about 10%.

   3. At the electrolysis temperature, the density of the mixed solution of cryolite and alumina is much lower than that of the molten aluminum. It floats on the molten aluminum to prevent aluminum from oxidizing, and it can separate aluminum and electrolyte more effectively.

   4. Cryolite has certain conductivity, so that the voltage of the electrolytic layer will not be too high.

   5. The cryolite solution has a certain fluidity at the electrolysis temperature, and the anode gas can be discharged from the electrolyte, which is conducive to the circulation of the electrolyte.

   6. In the molten state, cryolite basically does not absorb water, and the volatility is not very large, which will reduce the consumption of materials and ensure the stability of the electrolyte.

   The above is some analysis on cryolite, I hope it can be helpful to everyone.
