The cathodic reduction of neodymium ion has been studied using voltammetry and chronopotentiometrymethods in KCl-NaCl-NdCl3 melt saturated by metallic neodymium.The electrode reaction of cathodic re-duction of Nd ion has been found to be Nd2++2e→Nd in this molten salt system,and the reaction is a rever-sible and diffusion-controlled process.The electrochemical reduction potential of Nd is about-3.2V（versuschlorine reference electrode）.
