Tsukihashi等人[4]在1200 ° C下测量了碳饱和铁中硅的活度，Rego、Sigworth和Philbrook等人在1400 ° C下测定了Na 2 O-SiO2炉渣中SiO2的活度。这些炉渣中的Fed活度是从Ban-ya、Hind和Takezoe I61在1400 ° C下的结果中插值的。对于这些计算，假设在炉渣中不存在Fe 2 O3或FeS。因此，通过比较硫化物的容量计算使用的各种假设有关的反应控制的氧势的测定通过gasslag平衡，它是可能的推测是什么控制的界面处的氧势。在图1中，给出了来自气体-金属平衡的硫化物容量和使用反应[2]计算1400 ° C下氧势的分配比计算的硫化物容量，并与通过渣-气平衡测量的1200 ° C下的硫化物容量进行了比较。使用反应[1]计算氧势相当于假设反应，
Tsukihashi et al.[4] have measured the activity of silicon in carbon saturated iron at 1200~ and Rego, Sigworth, and Philbrook tSl have determined the activity of SiO2 in Na20-SiO2 slags at 1400~ The activity of Fed in these slags was interpolated from the results of Ban-ya, Hind, and Takezoe I61 at 1400~ For these calculations, it was assumed that no Fe20 3 or FeS was present in the slag. Therefore by comparing the sulfide capacity calculated using the various assumptions concerning the reactions controlling the oxygen potential to that measured by gasslag equilibration, it is possible to speculate on what is controlling the oxygen potential at the interface. In Figure 1, the sulfide capacity from gas-metal equilibration and that calculated from the partition ratio using reaction [2] for computing the oxygen potential at 1400~ is given and compared to the sulfide capacity at 1200~ measured by slag-gas equilibration. Using reaction [1] for computing the oxygen potential is equivalent to assuming that the reaction,
