| Abstract: | 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-NdCl3 from 700 to 850°C. The electrodeposited products were analysed by X-ray diffraction. The results indicate that the intermetallic compound Fe2Nd 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 Fe2Nd and Nd. |
