Abstract

In chronopotentiometric work on Fe2+ in a cryolite melt (Jentoftsen et al. in Metall. Mater. Trans. B, 2012, vol. 43B, pp. 869–74), after depletion of Fe2+ at the surface of the iron cathode was complete, continuing electrolysis produced a solution of Al in cryolite, provided that the time was less than a few hundred milliseconds. Potential–time curves indicate a diffusion-controlled, 2-electron reduction to form monovalent aluminum.
