Abstract

Cyclic voltammetry and cathodic polarization measurements were employed to study zirconium and uranium electrochemical behavior in LiCl-KCl eutectic based melts on solid (tungsten) and liquid (zinc, gallium, indium, Gz-Zn eutectic alloy) working electrodes. Deposition potentials of zirconium and uranium were determined. Ga-Zn alloy showed a difference of ca. 0.9 V in U and Zr deposition potentials. Thermodynamically achievable Zr/U separation factor in a “LiCl-KCl salt melt - liquid Ga-Zn alloy” system was experimentally determined.
