Abstract

The mixing enthalpies of liquid binary Ce–In alloys (0 < xIn < 1) at 1500 K are determined by isoperibol calorimetry. The thermodynamic properties of the liquid Ce–In alloys are calculated for the entire composition range using the model of ideal associated solutions. The thermodynamic activities of melt components show negative deviations from the ideal behavior. The mixing enthalpies are characterized by significant exothermic effects. The minimum mixing enthalpies of the melts are –43.8 ± 0.2 kJ/mol at xIn = 0.57.
