N2 - The effect of oxygen adsorption on the surface tension of liquid iron was investigated using the constrained drop method. Experiments were carried out at 1823 K and 1873 K (1550 °C and 1600 °C) under a CO2-H 2 gas mixture. The experimental results were interpreted using the Langmuir ideal adsorption model and Belton's two-step adsorption model; the latter model showed better agreement with the experimental results. According to the two-step model, the surface tension of liquid Fe-O alloys at 1823 K and 1873 K (1550 °C and 1600 °C) can be respectively expressed as follows: σ = 1882 260[0.25ln(1 + 2407ao) + 0.75 ln(1 + 72ao] [T =1823K(1550°C)] σ = 1834 267[0.25ln(1 + 1445ao) + 0.75 ln(1 + 46ao] [T =1873K(1600°C)].
