Thermodynamic properties of uranium in Ga–In based alloys

Thermodynamic properties of uranium in Ga–In based alloys

Activity of uranium was determined in gallium, indium and gallium–indium eutectic (21.8wt.%In) based alloys between 573 and 1073K employing the electromotive force method. In two-phase U–Ga–In alloys, uranium forms the intermetallic compound UGa3. Activity coefficients and solubility of uranium in G...

Zusammenfassung:Activity of uranium was determined in gallium, indium and gallium–indium eutectic (21.8wt.%In) based alloys between 573 and 1073K employing the electromotive force method. In two-phase U–Ga–In alloys, uranium forms the intermetallic compound UGa3. 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.
