The cyclic voltammetry, convolution voltammetry and chronopotentiometry were used to study the electrode process of Nd (III) reduced on iron electrode in molten NaCl‐KCl‐NdCl 3 from 700 to 850°C. The electrodeposited products were analysed by X‐ray diffraction. The results indicate that the intermetallic compound Fe 2 Nd forms first, and then the metallic neodymium deposits when Nd (III) is reduced on iron electrode. The Nd‐Fe alloys rich in neodymium can be obtained by electrolysis with iron cathode in molten chlorides. The Nd‐Fe alloys are composed of Fe 2 Nd and Nd.
