Abstract:The activity coefficients of a solute at infinite dilution,lγn,and interaction parameters, εni liquid Cu at 1 473 K are calculated by models.The calculation results show that the calculatedvalues are in accordance with the exl)erimental data on the whole.The ratios of same sign to lγn and εni reach 85% and 87.5% respectively.The main factors that affect lγn and εni are the electron density,nws,electronegativity,and molar volume I’ of solute i and solvent Cu.

 

Key words: liquid Cu interaction parameter thermodynamic calculation
