摘要：

The invention provides a potassium cryolite for aluminum electrolysis industry, which has a molecular formula: mKF·AlF 3 , wherein m is from 1 to 1.5. The low-molecular-ratio potassium cryolite (mKF·AlF 3 , and m is from 1 to 1.5) provided by the invention is used for aluminum electrolysis industry, and can improve the dissolvability of aluminum oxide, thus reducing the temperature of electrolysis and the consumption of power, raising the efficiency of electrolysis and lowering the comprehensive production cost.
