Abstract : The heat of formation of the compound AuSb2 at 273K and the partial gramatomic enthalpy of antimony in liquid tin at 623K were measured. Values of the partial gram-atomic enthalpy of gold and the enthalpy interaction coefficients of gold and antimony in liquid tin were calculated from the heat effects on solution of mixtures of gold and antimony in liquid tin at 623K. For the interpretation of the behavior of antimony and gold in dilute solution in tin non-zero values are assigned to the energies of bonds between like solute atoms relative to the pure solute state.
