Calculating Models on the Surface Tension of CaO-Al₂O₃-SiO₂ Slags

According to the coexistence theory of slag structure as well as the measured surface tension of CaO-Al₂O₃-SiO₂ at different temperatures and slag compositions, a calculating model of surface tension for the slag melts has been formulated. Calculated results agree with measured values,showing that the relationship between the surface tension and the mass action concentrations as well as temperatures of slag melts is correct.
