摘要：
The equilibrium potentials of Pr3+/Pr couple, triple Pr-Ga-In and U-Ga-In alloys vs Cl-/Cl(2)reference electrode at the temperature range 723-1073 K in fused LiCl-KCl-CsCl eutectic were carried out by open-circuit potentiometry. The principle thermodynamic properties, solubility and the activity coefficients of praseodymium in gallium-indium alloys, containing 20, 40 and 70 wt% indium were determined. It was established a strong interaction between atoms of Pr and liquid alloys. The temperature dependences of the separation factor of U/Pr couple vs the composition of gallium-indium alloys were calculated.
