Aluminium trifluoride is the main additive to the cryolite-based electrolyte in aluminium electrolysis. By Electrochemical Impedance Spectroscopy (EIS) the influence of AlF3 upon the kinetics and mechanism of the anodic reaction in 4 cryolite-alumina melts containing 2,4,6 and 8wt% of alumina and 11 wt% of AlF3 was determined at 1000 C.
