Abstract

The thermochemical properties of Ni-Sb alloys at 1241, 1363, and 1457 K in the range 0 <= x(Ni) <= 0.5 were studied by calorimetry. The ideal associated solution (IAS) model was employed to calculate the thermodynamic properties of Ni-Sb intermetallics and melts. The minimum mixing enthalpy is - 26.9 kJ/mole at x(Ni) = 0.58 and agrees with the values for Sb-3d-metal alloys. Our and literature data were used to predict the formation enthalpies of melts and intermetallics in the binary Sb-3dtransition metal systems.
