Abstract For the purpose of studying the influence of Ca on the activity coefficient of Al, f_(Al)~(Ca), in Ag, the dependence of the distribution ratio R_(Al)(=[%Al]_(Fe)/[%Al]_(Ag)) on Ca content in Ag was determined at 1600℃. The results obtained can be expressed as follows: R_(Al)=-2.91(%Ca)~2+3.51(%Ca)+3.05 and the interaction coefficient can be evaluated as lgf_(Al)~(Ca)=-0.441(%Ca)~2+0.476(%Ca) with Ca content within the range of 0 to 0.54%. The interaction parameters e_(Al)~(Ca) and e_(Ca)~(Al) are evaluated as 0.476 and 0.705 respectively. Preliminary results obtained on the distribution of Ce between Ag and Fe show that R_(Ce)(=[%Ce]_(Fe)/[%Ce]_(Ag)) is as low as 3.70×10~(-3). Besides, some thermodynamic functions are also deduced from the experimental results mentioned above.
