Carbothermal reduction of Titanium monoxide (TiO)

Journal of the Ceramic Society of Japan, 2008
The carbothermal reduction of TiO was investigated and compared with that of TiO2 using a thermodynamic approach and experiments. Cubic-TiO powder was synthesized using a high-energy mill to understand the reduction and carburization process. During the reduction and carburization process, TiO is found to be changed into TiC and Ti2O3 simultaneously at

Recycling of Mill Scale Into High‐Purity Iron Through Hydrogen‐Based Reduction

steel research international, EarlyView.
Mill scale, an iron oxide–rich steel by‐product, is difficult to recycle due to impurities. This study evaluates hydrogen‐based direct reduction and hydrogen plasma smelting reduction as low‐carbon recycling routes. Impurity segregation limits reduction kinetics. Direct reduction achieves 92% conversion in 180 min, while plasma reduction reaches 91% in
