Tellurium has mainly been used as an alloying element for resulfurized free-machining steel. It globularizes MnS inclusions and improves both machinability and mechanical properties of the steel. This effect is quite sensitive to tellurium concentration. Therefore, it should be controlled accurately during the secondary refining process, based on the thermodynamic properties of tellurium in molten iron. In the present study, Wagner's interaction parameters of various elements on tellurium were experimentally evaluated by the vapor-liquid equilibration, where the vapor pressure of tellurium was controlled using the transpiration method. The obtained values are compared with those of oxygen and sulfur, and they were found to correlate with Gibbs energy for the formation of corresponding oxides, sulfides, and tellurides. Furthermore, these relations could provide unreported interaction parameters from those available.
