Electrode processes in 3LiCl–2KCl–UCl3 melts: Investigation of temperature and uranium concentration influence

Electrode processes in 3LiCl–2KCl–UCl3 melts were studied at different temperatures and uranium concentrations using a variety of electrochemical techniques. It was found that the anodic process leads to the formation of U(IV) species while uranium metal is the only product of uranium(III) ions electroreduction. Characteristic potentials and limiting current densities were determined both for potentiostatic and galvanostatic regimes of uranium electrodeposition. Varying uranium concentration and temperature did not influence the mechanism of the cathodic reaction.
