Thermodynamic properties of uranium in Ga-In based alloys

Abstract Activity of uranium was determined in gallium, indium and gallium–indium eutectic (21.8 wt.% In) based alloys between 573 and 1073 K employing the electromotive force method. In two-phase U–Ga–In alloys, uranium forms the intermetallic compound UGa 3 . Activity coefficients and solubility of uranium in Ga–In eutectic were also determined in the same temperature range. Partial thermodynamic functions of γ-U in saturated alloys with gallium, indium and Ga–In eutectic were calculated.
