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

1. Pure aluminum can be produced more accurately than pure aluminum as long as it does not contain impurities from the outside.

2. Cryolite can dissolve alumina well. When the electrolysis temperature is 1000 ℃, 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 liquid aluminum. It floats on the liquid aluminum to prevent aluminum oxidation and more effectively separate aluminum and electrolyte.

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

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

The above is some analysis of cryolite. I hope it can be helpful to you.
