    • Abstract
  • The electrochemical process of Mg2+ on the tungsten electrode in NaCl-KCl-MgCl2 molten salt was studied by the way of cyclic voltammetry, chronoamperometry and chronopotentiometry at 1 073 K, MgCl2 was used as raw materialusing, using three-electrode and NaCl-KCl molten salt system, All tests were done at the AUTOLAB electrochemical workstation. Cyclic voltammetry results displayed that the electrochemical reduction of Mg2+ on the tungsten electrode in the NaCl-KCl-MgCl2 molten salt system at 1 073 K was one-step reaction transfer 2 electrons process, the electrode reaction was controlled by diffusion, the diffusion coefficient was 3.81×10-6 cm2/s and the electrode reaction was Mg2++2e-→Mg. The correctness of the cyclic voltammetry test results was verified by the chronopotential test. The fitting results of chronoamperometry data displayed that the electrocrystallization of Mg2+ on the tungsten electrode in NaCl-KCl-MgCl2 molten salt at 1 073 K was just an instantaneous nucleation mode.
