Abstract
Between 630 K and 1695 K, using two complementary calorimetric technics, the variations of the enthalpy of mixing function of the Au-Sn system were determined on the whole concentration range. These results have been compared with the many data, already published for this system, obtained from different technics. A critical analysis of our results at several temperatures confirmed the existence of an important variation of the enthalpy of mixing and enabled us to evaluate the heat capacity variations against temperature of this mixture : the minimum which can be noticed on the plot ΔCp = f (X) corroborates the conclusions drawn from the structural studies published previously.
