Abstract. The combined electroreduction of neodymium and cobalt ions Nd3+ and Co2+ of a KCl–NaCl-CsCl eutectic melt at 823 K was studied by cyclic and square-wave voltammetry and open–circuit chronopotentiometry. It is shown that the electroreduction potentials of cobalt and neodymium ions at different concentrations in the eutectic melt differ by about 1.5 V. With the combined content of cobalt and neodymium ions, there is a depolarization of the release of a more electronegative metal, neodymium, onto metallic cobalt previously released on a tungsten electrode, with the formation of intermetallic compounds NdxCoy of various compositions. The dissolution potentials of intermetallic phases based on neodymium and cobalt have been determined by open-circuit chronopotentiometry.

Keywords: ionic melt, neodymium, cobalt, intermetallic compound, electroreduction.
