Thermodynamic Properties of Ce–Ni Binary Alloys

The mixing enthalpies of liquid Ce–Ni binary alloys (0 < x Ni < 0.45 at 1430 K and 0.78 < x Ni < 1 at 1820 K) are determined by isoperibol calorimetry. The thermodynamic properties of the liquid Ce–Ni binary alloys are calculated for the entire composition range using the model of ideal...

Description
Summary:The mixing enthalpies of liquid Ce–Ni binary alloys (0 < x Ni < 0.45 at 1430 K and 0.78 < x Ni < 1 at 1820 K) are determined by isoperibol calorimetry. The thermodynamic properties of the liquid Ce–Ni binary alloys are calculated for the entire composition range using the model of ideal associated solutions. The thermodynamic activities of components show negative deviations from the ideal behavior. The mixing enthalpies are characterized by significant exothermic effects. The minimum mixing enthalpy of the melts is –34.8 ± 0.9 kJ/mol at x Ni = 0.66 and 1820 K.
