| Abstract: | A new model is proposed to estimate the density of molten slag,in which the temperature dependence of density is described by Arrhenius Law with the activation energy expressed as the linear function of optical basicity.Successful applications to the density calculations of CaO-Al2O3-SiO2 and Al2O3-CaO-MgO-SiO2 slag systems show that this formula can give a good description of composition and temperature dependence of density for molten slags.It is also found that the ionic band percentage of M-O band in MO... |
