Abstract
The first ever calorimetric results of integral enthalpies of mixing of liquid Li-Pb-Pd alloys were investigated with the use of an MHTC 96 drop calorimeter. Five separate measurements were performed for such liquid alloys as (Li0.5Pb0.50)1−xPdx, (Li0.25Pb0.75)1−xPdx at 926 K, (Pb0.90Pd0.10)1−xLix at 1005 K, as well as (Li0.75Pb0.25)1−xPdx, and (Pb0.60Pd0.40)1−xLix at 1026 K. Based on the authors' own equations describing the excess Gibbs energy of binary Li-Pb, Li-Pd, and Pb-Pd liquid solutions, and the experimental values of integral molar enthalpy of mixing of liquid Li-Pb-Pd alloys presented in this work, the ternary interaction parameters were calculated. Finally, the values of molar thermodynamic functions of liquid Li-Pb-Pd alloys were calculated and presented in the form of tables and figures.
