Abstract
The glass and glass ceramics in the CaO–MgO–Al2O3–SiO2 system were successfully synthesized from the stainless steel (SS) slag. The effect of slag content on the viscosity and conductivity of the glass melt, as well as the crystallization behavior and microstructure of the glass ceramics were investigated. The results proved that the viscosity of the molten glass decreases with increasing temperature and SS slag content; however, an inverse relation is observed in case of conductivity. Furthermore, the logarithm of viscosity varies linearly with that of conductivity. Thus, the viscosity and conductivity values can be calculated with respect to each other under melting conditions. The crystallization activation energies range from 335 to 473 kJ/mol, which are significantly higher than the viscous energies and conductance activation energies. Additionally, the obtained glass ceramics comprise augite, gehlenite, and wollastonite. Furthermore, augite grain coarsening and the number of crystals increase with increasing SS slag content.
