Calcium ferrite phases (CaO·Fe₂O₃ and CaO·2Fe₂O₃) are promising intermediate compounds for controlling phosphorus and sulfur partition in steelmaking slags. Our research focuses on synthesising calcium ferrite from waste steel slag and iron oxide residues, creating a low-cost slag conditioner that improves dephosphorisation efficiency. Lab-scale trials show 30–40% improvement in P₂O₅ capacity compared to conventional lime-based slags. The project explores phase stability, kinetics of formation, and optimal CaO:Fe₂O₃ ratios for different steel grades.
