Abstract. The process of combined electroreduction of neodymium and boron ions in the eutectic melt KCl – NaCl – CsCl on a tungsten electrode at 823 K was studied using cyclic and square-wave voltammetry and chronopotentiometry. Established the effect of the anionic composition of the electrolyte on the electroreduction of neodymium ions. It was shown that the introduction of fluoroborate ion shifts the potential of electroreduction of neodymium ions to the negative region and changes the nature of the electrode process from reversible, during electroreduction of chloride complexes, to irreversible, during electroreduction of chloridefluoride complexes. Conditions for the joint electroreduction of neodymium ions with boron ions against the background of chloride melts have been found, on the basis of which the fundamental possibility of electrochemical synthesis of boride phases at a temperature of 823 K in a eutectic melt of KCl – NaCl – CsCl has been demonstrated.
