説明

By using a double adiabatic wall calorimeter, the heat of fusion and specific heat of the seven gold compounds of AuGa, AuGa2, AuIn, AuIn2, AuSn, AuSb2 or AuTe2 were determined.<BR>Equations for the excess integral free energy of mixing ΔGE of liquid binary alloy systems involving stoichiometric compounds, were derived as a function of heat of fusion of the compound and the liquidus coexisting with the compound. From the obtained data and the derived equations, ΔGE of the liquid gold binary alloys of Au-Ga, Au-In, Au-Sn, Au-Sb or Au-Te were calculated, and it was clarified that the calculated values depend basically on the accuracy of the liquidus.
