Reduction of Ilmenite Through Microwave Plasma

Ilmenite was reduced through microwave plasma-assisted chemical vapor deposition with continuously flowing hydrogen and methane gas. The reduction products were analyzed by XRD and SEM technology, and the component products were TiO₂-Carbon Nanotubes (CNTs) composite powders. The reduction process was in good agreement with the Jander equation. Compared with other reduction process by kinetics analysis, microwave plasma could significantly facilitate the reduction process at low temperature.
