Page No. 9-12
Abstract
The thermodynamic properties of the lead based binary liquid alloys are often found to vary
considerably from the ideal values. Here two such alloys—lithium-lead and sodium-lead—have
been considered. Efforts are made to compute their entropies of mixing at different concentrations
of the constituent species by using Flory's model. In this course the temperature dependence of the
interchange energy has also been introduced. The results indicate that the size effect in the present
alloys may not be an important factor for shaping the entropy of mixing as for other thermodynamic
calculations.
Key words: Flory’s model, Size effect, Interchange energy, Free energy of mixing, Heat of mixing.
