Abstract
Using high-temperature isoperibol calorimetry, we have determined the partial enthalpy of mixing of nickel in Ge-Ni melts at 1800 ± 3 K in the composition range 0 < x Ni < 0.7 (\(\Delta _{mix} \bar H^\infty \) (Ni) = −76.0 ± 4.8 kJ/mol). The results have been used to evaluate the partial enthalpy of mixing of germanium and the integral enthalpy of mixing (Δmix H min = −37.9 ± 0.6 kJ/mol at x Ni = 0.6). The thermochemical data and germanium activity in Ge-Ni melts have been analyzed in comparison with those reported earlier, and the most reliable thermodynamic functions of the Ge-Ni melts at 1870 K have been determined.
