Thermodynamic properties of alloys of the Ge-Mn system. Review

The thermodynamic properties of alloys of the Ge-Mn system are analyzed. Concentration dependences of thermodynamic mixing functions are obtained with the use of adequate published data. The variation of the heat capacity during the dissolution of manganese in melts of Ge-Mn is estimated using the temperature dependence of the partial enthalpy of mixing of manganese. Partial excess entropies of mixing are computed with the use of partial entropies of mixing obtained by the method of calorimetry and of partial excess entropies of mixing measured by the method of electromotive forces. Integral thermodynamic functions of mixing are computed from the corresponding partial quantities.
