Abstract:

Electrochemical behavior of neodymium and uranium in a molten Nd(U)-(Ga-xAl)/3LiCl-2KCl system (x = 1.5; 5.0 and 20.0 wt\% Al) between 723 and 823 K was studied. Temperature dependencies of apparent standard potentials of Nd-(Ga-Al) and U-(Ga-Al) alloys were determined versus Cl-/Cl-2 reference electrode. Neodymium and uranium activity coefficients and Nd/U separation factor were calculated. Partial excess free Gibbs energy, partial enthalpy of mixing and partial excess entropy of Nd-(Ga-Al) and U-(Ga-Al) alloys were estimated.
