Abstract
A quasi-lattice model is used to explain the concentration dependence of the free energy of mixing, heat of mixing, excess entropy of mixing , chemical short-range order parameter, and concentration-concentratio n fluctuation in the long wavelength Limit for Bi-Te molten alloys. Th e results show that the molten alloys form a complex of the form Bi2Te 3, with chemical ordering throughout the whole concentration range wit h a peak at a concentration of 0.50.
