In order to understand the sulfur segregation at the molten iron and solid carbon interface, the initial contact of molten iron with solid carbon was investigated at different sulfur concentrations. It is found that the contact angle does not depend on the sulfur concentration within the experimental concentration region (0.008 wt.%S to 0.035 wt.%S). The mean value was estimated to be 93°. Assuming an ideal adsorption isotherm, it was found that sulfur segregation at the metal-graphite interface was not so considerable, compared to the surface segregation.
