Abstract用固体电解质定氧探头测定碳饱和铁水中氧活度的方法研究了在1510℃时与碳饱和铁水相平衡的 CaO-SiO_2-V_xO_y 系熔渣中 V_2O_3,SiO_2,MnO 及FeO 的活度系数,并考察了光学碱度对它们的影响.结果表明,当光学碱度从0.554升至0.760时,(V_2O_3)的活度系数将从5.33×10~(-3)降至4.24×10~(-5),(SiO_2)的活度系数也将随光学碱度的升高从1.155降低至0.068,而(MnO)的活度系数却随光学碱度的增加而增大,变化范围为0.53~2.62,在该实验体系中(FeO)的活度系数在0.132~0.82的范围内变化,且在光学碱度∧=0.65时取得极大值γFeO=0.82,∧≠0.65时,γFeO 均将减小.
