Surface phenomena play a major role in metallurgical processes; their operation results, among others, from the surface tension of liquid oxidic systems. One of the methods of determining surface tension of oxidic systems is performing calculations with Butler’s method. Surface tension was calculated for two- and three-component liquid oxidic systems typical of metallurgical processes. The determined dependence of surface tension in FeO-SiO₂ at temp. 1773 K and CaO-SiO₂ at temp.1873 K showed that with the growing participation of SiO₂ surface tension decreased. Analogous calculations were performed for three-component systems: CaO-Al₂O₃-SiO₂ and MnO-Al₂O₃- SiO₂. The results of calculations of surface tension were determined for temp. 1873 K and compared with the results obtained by T. Tanaka et al. [19]. In both cases the increase of Al₂O₃ content resulted in a growth of surface tension. The simulation results were higher than experimental result, as compared to the literature data.
