英文摘要: Electrochemical behavior of Nd was studied in NaCl-KCl melt on W and Cu electrodes via cyclic voltammetry and chronopotentiometry. Generally, the reduction of Nd3+ takes place in two consecutive steps in molten chlorides, such as LiCl-CaCl2, LiCl-BaCl2, CaCl2-NaCl, LiCl-KCl melts. However, the reduction of Nd3+ ions was found to be through a one-step process: Nd3+ + 3e → Nd. The co-reduction behavior of Nd3+ and Cu2+ ions and the mechanisms of alloy formation were investigated in NaCl-KCl melt on W electrodes at 988 K (715 °C). Four potential plateaus corresponding to four different kinds of Cu-Nd intermetallic compounds were detected. Cu-Nd alloys were prepared on Cu electrodes at 988 K...
