Iron(II) oxide - Wikipedia

FeO can be prepared by the thermal decomposition of iron(II) oxalate. FeC 2 O 4 → FeO + CO 2 + CO. The procedure is conducted under an inert atmosphere to avoid the formation of iron(III) oxide (Fe 2 O 3). A similar procedure can also be used for the synthesis of manganous oxide and stannous oxide.

Equation of state and phase diagram of FeO - ScienceDirect

15/04/2011  The relevant reaction is Fe 1 − xO + xFe ⇄ FeO, and the pressure dependence of this reaction is determined by the volume difference V(FeO) − V(Fe 1 − xO) − xV(Fe). The present study provides the equation of state of FeO, and equations of state exist for both fcc and hcp phases of Fe (e.g., Campbell et al., 2009, Dewaele et al., 2006), but the equations of state of wüstites are not ...

For NAFO, it can be seen from Fig. 7(a) that, during the reduction of the fresh oxygen carrier, the Fe 2 O 3 is reduced subsequently to Fe 3 O 4, FeO and finally Fe, without any detectable formation of FeAl 2 O 4, i.e. the interaction between FeO and Al 2 O 3 was absent during the first cycle, and hence the initially high X seen in Fig. 6(a).

Difference Between FeO and Fe2O3 Compare the

19/11/2020  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.
