In order to derive the values of the interaction parameter, $e_O^C$ , in carbon‐saturated {Fe‐C} liquid alloys, as defined below;$$\log \,h_O = \log [\%{\rm O}] + e_O^C [\%{\rm C}]_{{\rm Sat}} ,$$ an electrochemical technique incorporating zirconia solid electrolyte was applied for the direct measurements of the Henrian activities of oxygen, h O , between 1623 and 1723 K, while the concentrations of oxygen and carbon in pct by weight, [%O] and [%C] Sat , respectively, were determined by using a conventional LECO analyzer. The results can be summarized as$$e_O^C = - 0.17 \pm 0.02\;{\rm and}\;[\%{\rm O}] = 7.1\,h_O$$
