Abstract
Inert oxygen evolving anodes are much desired to replace carbon anodes in proposed electrolysis processes in molten salt electrolytes containing dissolved oxides. Experiments were performed in molten CaCl2-NaCl-CaO at 650 oC and KCl-LiCl-LiO2 at 450 - 550 oC. The behaviour of nickel ferrite and tin oxide based anodes was studied by long time electrolysis. Voltammetry was used to study the electrochemical behaviour of dissolved oxide complexes.
