Enthalpy of mixing of liquid Ag-Li-Sb alloys

Ag-Li-Sb is a ternary system that has not yet been studied in terms of thermodynamic investigations. The partial and integral enthalpies of mixing of liquid Ag-Li-Sb alloys at 980 K were determined applying drop calorimetry. The investigations were performed along five sections by the addition of lithium to alloys with fixed Ag to Sb molar ratio of 1:1 and 1:4, by the addition of silver to alloys with fixed Li to Sb molar ratio equal to 1:9, 3:7 and 1:1. Experimental data were compared and discussed with Muggianu and Toop extrapolation models. From experimental ternary data the range of liquid at 980 K was deduced.
