Thermodynamic description of the Ge-In-Li liquid alloys

Abstract

The integral molar mixing enthalpy of liquid ternary Ge-In-Li alloys was investigated using drop calorimetry method. Five separate measurements of (In0.75Li0.25)1-xGex, (In0.50Li0.50)1-xGex, and (In0.25Li0.75)1-xGex, (Ge0.50Li0.50)1-xInx and (Ge0.50In0.50)1-xLix liquid alloys at 1076K were studied. Next, the ternary interaction parameters were calculated based on available in literature equations describing the excess Gibbs energy of binary Ge-Li, Ge-In and In-Li liquid solutions (the Redlich-Kister relation), and presented in this work experimental values of mixing enthalpy of liquid Ge-In-Li alloys. Finally, the values of partial and molar thermodynamic functions of liquid ternary Ge-In-Li alloys for the fixed temperature of 1076K and for the constant rations of In/Li, Ge/Li and Ge/In as mentioned above were calculated and presented in the form of tables and figures.
