Özet

Glass-ceramic materials were developed from the blast-furnace slags by mixing 5 wt% Cr₂O₃ and 5 wt% Cr₂O₃ + 5 wt% TiO₂. The samples were nucleated for 18 h at 780 °C and crystallized for 20 min. at 905 °C, respectively. SEM and SEM/EDS investigations revealed the presence of clover-shaped TiO₂ particles in the glassy matrix of the sample nucleated with 5 wt% Cr₂O₃ + 5 wt% TiO₂ and polygonal-shaped Cr₂O₃ platelets for both samples. XRD scans revealed the presence of akermanite (2CaO.MgO.2SiO₂) and gehlenite (2CaO.Al₂O₃.SiO₂) peaks indicating the existence of the mellilite solid solution for the crystallized glass-ceramic samples.
