Internal pressure, excess internal pressure, energy of vaporization, excess energy of vaporization and solubility parameter of Pb–Sn molten binary liquid mixture were calculated over a wide range of temperature and composition. A quantitative treatment has been carried out for these thermodynamic properties with the help of Hildebrand equation. Also, interaction study has been made in the light of excess thermodynamic functions.

Keywords: Molten, internal pressure, elevated temperature, binary mixture, solubility parameter, hildebrand equation.
