  • Kinetics of Magnetite (Fe3O4) Oxidation to Hematite (Fe2O3

    Thermogravimetric analysis (TGA) of magnetite (Fe3O4) oxidation was conducted at temperatures ranging from 750 to 900 C over 10 oxidation cycles. Oxidation experiments were carried out in a continuous stream of air for period of 30 min. The oxidized magnetite (Fe3O4), which resulted in formation of hematite (Fe2O3), was then reduced by using continuous stream of CO (5% and 10%)
