The interaction between Fe2O3‐bearing molten slag and MgO‐C refractory containing calcium magnesium aluminate antioxidant

open access: yesJournal of the American Ceramic Society, Volume 108, Issue 10, October 2025.
Abstract The interaction behavior between iron oxide‐bearing slags and carbon‐bonded MgO refractory (MgO‐C) containing calcium magnesium aluminate (CMA) was investigated at 1400°C, 1500°C, and 1600°C. After the iron oxide was reduced by the carbon from the MgO‐C refractory, a significant amount of MgO and metallic iron was observed to precipitate and ...
