Molecular formula: Na3AIF6 also as 3NaF·AlF3

It is mainly used as the flux in the aluminium electrolyzing bath

1Adjustable molecular ratio. The low-molecular ratio cryolite (ratio: 1.3-1.8) can replace AIF3 partly or completely with high yield in the aluminum electrolyzing. The mid-molecular ratio cryolite (ratio 1.8-2.5) can increase the electrolyte level. The high-molecular ratio cryolite (ratio 2.5-3.0) quickly starts up aluminum electrolyzing bath and turn to normal operation.

2.Lower cost. It can economies the power and reduce the cost in aluminum electrolyzing. It has a strong competitive ability.

3Good fluidity. Suitable for automatically feeding in the aluminum smelters and promoting the technology reformation and progress.

4High contents of F, Al, less contents of residues like SiO2 Fe2O3 SO42- P2O5.

5Low free-water and loss of ignition.
