| Abstract Scope |
The co-reduction of multicomponent oxide mixtures using hydrogen as a reductant offers a promising alternative toward sustainable alloy production via a single, integrated, and synergistic process. In this study, we investigate the hydrogen-based direct reduction (HyDR) of oxide mixtures comprising Co3O4, Fe2O3, Mn2O3, and NiO. The samples were reduced in a hydrogen atmosphere using a thermogravimetric setup. Microstructural characterization revealed the complete reduction of Co3O4, Fe2O3, and NiO, along with partial reduction of Mn2O3 to MnO. Complementary thermodynamic calculations were conducted to elucidate the underlying reaction mechanisms. The findings offer fundamental insights into the HyDR process and inform the optimization of process parameters for the sustainable production of multicomponent alloys. |
