Roulette liquid theory has been applied to the partially miscible system of the Pb-Zn mixture. A partition function for the binary mixture is developed using Roulette liquid theory, on the basis of the fact that potential energy is a function of characteristic molecular constant. We can obtain the coexistence curve of Pb-Zn system which is in good agreement with the experimental result and explain some theoretical defects of lattice model.
