Abstract: The electrochemical behavior of Sc3+ in LiF-NaF system was investigated. The cyclic voltammetry and chronopotentiometry were used to investigate the reduction mechanism of the electrochemical deposition of Sc3+ to Sc on Ag electrode in LiF-NaF system at 1043 K. Experimental results indicate that the electroreduction of Sc3+ to Sc is a reversible process with simple 3-electron transfer in one step controlled by diffusion.
