KF-AlF3-Al2O3-based melts are promising media for the electrolytic production of aluminum in next-generation energy efficient cells. This work analyzes the dissolution of Al2O3 in the KF-AlF3 melt with a mole ratio [KF]/[AlF3 ] = 1.5 mol/mol at 785掳C using cyclic voltammetry and the...
The solubility and dissolution rate of alumina in NaF-KF-AlF 3 -LiF-CaF 2 melt with a cryolite ratio (CR) ranging from 1.5 to 1.8 were investigated by the rotating corundum disk method at 1073 K to 1153 K. The effect of the composition and temperature of the melt on the solubility ...
