用Ag浴等活度法测定了1450℃下Fe-B-Si三元系熔体的两条等活度线;用Si浓差电池EMF法测定了Ag-Si合金(银浴)的α_(Si).由实验测定结果计算了Si的活度系数及活度交互作用系数,得到 lnγ_(Si)=-3.19,ε_(Si)~(Si)=7.0,ρ_(Si)~(Si)=6.5, ε_(Si)~B=16.0,ρ_(Si)~B=-12.0,ρ_(Si)~(Si,B)=40.8
Iso-activity lines of Si in ternary Fe-B-Si melts were measured at1450℃ with Ag-bath medium method. 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
