Abstract

The invention provides a sodium cryolite for aluminum electrolysis industry, which has a molecular formula: mNaF.AlF 3 , wherein m is from 1 to 1.5. The low-molecular-ratio sodium cryolite (mNaF.AlF 3 , and m is from 1 to 1.5) provided by the invention is used for aluminum electrolysis industry, and can reduce the temperature of electrolysis and the consumption of power, raise the efficiency of electrolysis and lower the comprehensive production cost.
