Effect of alloying elements (oxygen, sulfur, selenium and tellurium) on the surface tension of molten iron and contact angle of molten iron on solid oxide (sintered alumina) were investigated with sessile drop method at 1 600°C. The surface tension of molten iron decreased with addition of these elements and tellurium was highest surface active element in this work (Te>Se>S>O). The contact angle of molten iron on alumina decreased with increasing of oxygen content in molten iron but increased with increasing of selenium or tellurium content in molten iron. The sulfur content did not have effect on the contact angle. The work of adhesion and interfacial energy between molten iron and alumina were calculated by using the experimental values of surface tension and contact angle.
