Abstract

A novel method of molten salt electrolysis and novel electrolytic cells for molten salt electrolysis wherein the anodes for the electrolysis are comprised of a self-sustaining matrix of sintered powders of at least one oxycompound such as oxides, multipleoxides, mixed oxides, oxyhalides and oxycarbides, of at least one metal selected from the group consisting of lanthanum, terbium, erbium, ytterbium, thorium, titanium, zirconium, hafnium, niobium, chromium and tantalum and at least one electroconductive agent, the said anode being provided over at least a portion of its surface with at least one electrocatalyst for the electrolysis reaction and bipolar electrodes for the said cells which electrodes are resistant to corrosion in molten salt electrolysis and have good electroconductive and good electrocatalytic activity.
