Quasi-lattice model has been used to explain the concentration dependence of the free energy of mixing, excess entropy of mixing, chemical short-range order parameter and concentration–concentration fluctuation in the long wavelength limit for S-Te molten alloy. Results show that the molten alloy does not form a complex of the form S-Te3 rather, there is phase separation.

Keywords: free energy of mixing, chemical short range order and concentration-concentration fluctuation in the long wavelength limit
