Thermodynamics and separation factor of uranium from lanthanum in liquid eutectic gallium-indium alloy/molten salt system

• The behavior of lanthanum and uranium on liquid gallium-indium eutectic alloy was carried out. The experiments were done in fused 3LiCl-2KCl eutectic vs. Cl−/Cl2 reference electrode at the temperature range 723–823 K. Thermodynamic properties of La-Ga-In and U-Ga-In alloys and the separation factor U/La were calculated.

This work presents the electrochemical study of lanthanum and uranium compounds in fused 3LiCl-2KCl eutectic vs. Cl−/Cl2 reference electrode in the temperature range 723–823 K on liquid gallium-indium eutectic alloy. Thermodynamics and the activity coefficients of lanthanum and uranium were studied. The separation factor of uranium from lanthanum on gallium-indium eutectic alloy was determined.
