The interfacial tension at the Na2O-Li2O-SiO2-B2O3 slag-steel boundary has been determined in the temperature range of 1 803-1 873K by sessile drop method with the transmission X-ray technique. It was found that the variation of interfacial tension with temperature in the system of molten steel/Na2O-Li2O-SiO2-B2O3 slag in the temperature range of 1 803-1 873K is pretty little. The interfacial tension remarkably decreases with increasing the oxygen and/or sulfur content in molten steel. It suggesed that the oxygen and sulfur dissolved in molten steel act as a surface-active solute at the slag-steel interface. Consequently, the interfacial tension depends, in most part, on the oxygen content in molten steel, but the composition of the slag has a minor effect on the interfacial tension. In order to clear the effect of slag composition on the interfacial tension, the experimental results are discussed. The interfacial tension is observed to increase with increasing Na2O and Li2O contents, and decrease with increasing silica content in slag. The influence of B2O3 on the interfacial tension is pretty little.
