Electrode Process of Y^(3+)Ion on Molybdenum and Nickel Electrodes in YCl_3-NaCl-KCl Melt

摘要

The electrode process of Y3+ion on molybdenum and nickel electrodes has been studied by cyclicvoltammetry and chronopotentiometry in the YCl3-NaCl-KCl melt.The overall charge transfer process is atwo-step reaction:Y3++e=Y2+;Y2++2e=Y.Yttrium reduced on the nickel electrode can form a series of Ni-Yalloys.X-ray diffraction analysis was employed to determine the alloy compositions formed under different con-ditions.
