The activity of Si in Ag-Si alloy was alsodetermined by means of the EMF measurement of a Si-concentration cell in whicha double-tubed ZrO_2 electrolyte was used. A method has been proposed for calculat-ing ln γ°_(Si) and the first and second order interaction coefficients from the experi-mental data; Following results have been obtained: ln γ°_(Si)=-3.19, ε_(Si)~(Si)=7.0, ρ_(Si)~(Si)=6.5, ε_(Si)~B=16.0, ρ_(Si)~B=-12.0 and ρ_(Si)~(Si,B)=40.8 Key words:  Fe-B-Si system      activity      activity coefficient      activity interaction coefficient      Ag-bath medium method      Received:  18 February 1988      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1988/V24/I2/155 1 Wagner C.
