Reducing burning is the first problem to improve the quality of cryolite.

Burning is an important test indexes of cryolite, reduction is 550 ℃, cryolite materials 0.5 h, burning loss percentage rate.
The decline of cryolite was a new indicator of the national standard in 1999.
With the progress of society and the development of aluminum electrolytic industry, industrial production automation level and environmental protection are important and urgent to improve speech &drama, as the raw material of aluminum electrolysis, cryolite, its performance also needs to improve.
Cryolite burning reduction directly influence its use in the production of aluminum electrolytic effect. Burning high, will cause the cryolite hydrolysis, float in the sky, such as low material utilization ratio, aggravating environmental pollution problems. Burning down the low is used, the better the results.

Therefore, reducing the burning reduction is the first problem of improving the quality of cryolite products and producing high quality crystal stone.
