Metallic solutions and calorimetry

AbstracL In materials science, accurate high temperature thermodynamic measurements are needed to predict and to understand the properties of ncomponents systems. Two examples have been chosen to highlight this problem: i) from molar heat capacity determinations, the miscibility gap of the solid HgTe-CdTe system has been found; ii) in spite of several empirical and theoretical models, measurements of the enthalpy of formation of Cd-Ga-In-Sn-Zn liquid alloys are unavoidable. These examples show the necessity to develop very precise calorimetric methods in the high temperature range
