摘要：

The mixing enthalpies of the La–Ni binary liquid alloys are determined by isoperibol calorimetry in the composition range 0 < xNi <0.45 at 1430 K and 0.75 < xNi < 0.80 at 1800 K. The thermodynamic properties of the La–Ni binary liquid alloys are calculated for the entire composition range using the model of ideal associated solutions and reliable published data. The thermodynamic activities of components show negative deviations from the ideal behavior; the mixing enthalpies are characterized by exothermic effects. The minimum mixing enthalpy of the melts is –28.0 ± 0.2 kJ/mol at xNi = 0.6.
