Study of the electrochemical behavior of U(III) ions on liquid Cd electrode and preparation of the U–Cd intermetallic compound in fused 3LiCl–2KCl eutectic

The uranium (III) ions behaviour in fused 3LiCl–2KCl eutectic versus the Cl−/Cl2 reference electrode in the temperature range of 723–823 K on the liquid cadmium electrode by transient electrochemical techniques on the tungsten or molybdenum electrodes was studied. The mechanism of electrochemical reduction on cadmium cathode and the influence of temperature, cathode current density and the duration of electrolysis were studied. The activity coefficients and the base thermodynamic properties of uranium in fused U–Cd/3LiCl–2KCl system were calculated.
