The mole fractions of liquid species, solution heat capacity, and enthalpy of mixing in a Te-rich liquid for CdTe crystal growth are calculated using the full associated liquid model for the liquid phase. The calculation results have shown that CdTe is the major solute species in the liquid and temperature effect on its dissociation is small over the temperature range of interest. Temperature dependences of the liquid heat capacity and enthalpy of mixing for different atomic compositions have also been given, which provides information on determination of growth temperature and understanding of the liquid state. The calculations indicate that design of a preheating process of the liquid may be important for high quality crystal growth of CdTe material.
