Difference Between FeO and Fe2O3 Compare the

2020-11-19  The key difference between FeO and Fe2O3 is that FeO has iron in +2 oxidations state, whereas Fe2O3 has iron in +3 oxidation state.. In brief, FeO and Fe2O3 are oxides of iron but having the iron atoms in different oxidation states. FeO is the chemical formula of iron(II) oxide while Fe2O3 is the chemical formula of iron(III) oxide.

The reduction mechanism and kinetics of Fe2O3 by

2017-3-23  The reduction of Fe2O3 by H2 was conducted in a thermogravimetric analyzer at 973–1172 K. The phase analysis of reduction products in different reduction stages illustrated that Fe2O3 → Fe3O4 and Fe3O4 → FeO proceed simultaneously; hence, the reduction process is a two-step reaction, in the sequence of Fe2O3 → FeO and FeO → Fe.

Reduction of Fe2O3 with hydrogen - ScienceDirect

2010-6-15  The reduction of Fe 2 O 3 with hydrogen was studied. The thermodynamic analysis of the process implied that temperature-programmed reduction of the oxide should proceed in three steps, i.e. Fe 2 O 3 → Fe 3 O 4 → “FeO” → Fe, at X H 2 O / X H 2 ratio over 0.35, but in two steps, i.e. Fe 2 O 3 → Fe 3 O 4 → Fe, below that value. The idea was verified by TPR and XRD studies.

[email protected] Calculation FeO total to "FeO and ...

2020-8-14  Could I get the FeO and O2 value from the equation "FeO total = FeO + 0.8998*Fe2O3" or molar stoichiometric equation Fe2O3 = 0.5O2 + 2FeO? It is a dumb question, but I think it is important to know the stoichiometric calculation of FeO and Fe2O3 separation. Thank you for read. I would be greateful if I could get advice on that.
