| Abstract Scope |
The influence of the Cr2O3 content on the surface tension of CaO–SiO2–9.25wt.%MgO–14.7wt.%Al2O3–22wt.%TiO2–Cr2O3 slag system was investigated in the temperature range of 1450–1550°C using the ring method. The mechanism of the changes in surface tension with different Cr2O3 content in slag was analyzed from the perspective of model and ion theory in the melts. Increasing the Cr2O3 content from 0 to 3 wt.% caused an increase in the surface tension for the reason that the surface tension of Cr2O3 is the largest and that of SiOCr2 is the smallest in the components of the slag. Another reason is that the anions are repelled to the surface layer of the slag and adsorbed. The surface tension decreased with increasing temperature. This is because the decrease of interaction force between the ions and the reduction of the bulk phase density between the two phases adjacent to the surface layer. |
