DOI: 10.1016/j.ceramint.2020.08.249
Abstract: Abstract Stainless steel slag-based CaO–Al2O3–MgO–SiO2 (CAMS) glass ceramics were prepared by spark plasma sintering (SPS), which provided enhanced hardness, reaching a maximum of 16.3 GPa at 800 °C. The crystallinity of diopside (the main crystalline phase) increased with… read more here.
