“…8 Later in 1970, for the specific motivation of electrochemical separation of fission product impurities, HOSHIN et al studied the electrochemical and thermodynamic properties of yttrium and yttrium-zinc alloys in fused LiCl-KC1 eutectic. 9 Since then, many works were conducted to extend the yttrium electrochemistry in chloride molten salts, such as the electrochemical behaviors on different electrodes such as Ni, [10][11][12][13] Cu, 14 Mo 12 and W, 2,13 co-reduction mechanisms with other cations, 6,15,16 investigations of cathodic kinetics, diffusion coefficient and electrocrystallization mechanism. 2 Castrillejo et al found that the nucleation mechanism of yttrium deposition on the tungsten electrode is an instantaneous nucleation process in the eutectic LiCl-KCl.…”
