POTASSIUM CRYOLITE APPLICABLE IN ALUMINUM ELECTROLYSIS INDUSTRY AND PREPARATION METHOD THEREFOR

摘要

Provided in the present invention is a potassium cryolite applicable in aluminum electrolysis industry. The molecular formula of the potassium cryolite is mKF-AlF₃, where m is 1 to 1.5. The potassium cryolite of low molecular ratio (mKF-AlF₃, where m is 1 to 1.5) provided in the present invention is applicable in aluminum electrolysis industry and allows for improved solubility of aluminum oxide, reduced electrolytic temperature, reduced electrical power consumption, improved electrolytic efficiency, and reduced overall production costs.
