Aluminium dissolved in cryolite-alumina melts migrates in the direction of the positive pole by passage of current . By a modified moving boundary technique the dissolved metal was found to separate into two zones with different mobilities . For the cryolite composition at 11100°C the apparent mobil

The oxidation of dissolved metal in acidic cryolite melts has been studied at tungsten, classy carbon and graphite electrodes using the techniques of cyclic voltammetry and chronopotentiometry. The reaction was found to be diffusion controlled and quasi-reversible with n = 2, suggesting that monoval

When a constant cathodic current is applied to an aluminium electrode in a Na3A1F6-AlaO, melt at lOlO"C, the potential decreases gradually and linearly with the square root of time to more negative values. Pronounced potential oscillations occurred at cds above 2A/cm2 and the evolution of sodium gas
