ABSTRACT
This work presents the results of a study of apparent standard potentials of La-(Ga-In) and U-(Ga-In) alloys vs. Cl /Cl2 reference electrode at the temperature range (723 823) K in fused Me(Ga-In)/LiCl-KCl (3:2 mol ratio) system by potentiometric method at zero current. Lanthanum and uranium activity coefficients and La/U separation factor in gallium-indium alloys containing 40 and 70 wt% indium were determined. Partial excess free Gibbs energy, partial enthalpy of mixing and partial excess entropy of La-(Ga-In) and U-(Ga-In) alloys were calculated. The efficiency of separation of La from U was estimated.
