Abstract
Integral molar enthalpies of mixing were determined by drop calorimetry for (Ag-Li) liquid alloys at two temperatures (1253 and 873)K. The integral molar enthalpies of mixing are negative in the entire range of concentrations. For the mole fraction of lithium XLi=0.5664, minimum value of the integral enthalpy of mixing of at ΔHm=−11.679kJ/mol was observed. For (Ag-Li) liquid alloys, between T=(873 and 1253)K no temperature dependence was observed. Ab initio molecular dynamics was used to simulate liquid phase structures at T=873K (Li-rich side) and at T=1250K (Ag-rich phase) for subsequent calculation of the vibrational energy, respectively. Our measured and calculated data were compared with literature data.
