摘要：

Partial and integral enthalpies of mixing of melts of the Eu-Pd system were determined by calorimetry at 1300 K in the concentration interval of 0 < xPd < 0.37. It was established that the first partial enthalpy of mixing of Pd was −158 ± 2 kJ/mol. The thermodynamic properties of Eu-Pd melts were simulated according to the theory of ideal associated solutions over a wide interval of concentrations and temperatures. It was shown that the activities of components display strong negative deviations from Raoult’s law, and the minima of the integral Gibbs energies and enthalpies of mixing were found at xPd = 0.65.
