Iron(II) oxide - Wikipedia
Iron (II) oxide or ferrous oxide is the inorganic compound with the formula FeO. Its mineral form is known as wüstite. [ 3 ][ 4 ] One of several iron oxides, it is a black-colored powder that is sometimes confused with rust, the latter of which consists of hydrated iron (III) oxide (ferric oxide).

Jun 8, 2016 · We show that the mineral goethite, FeOOH, which exists ubiquitously as ‘rust’ and is concentrated in bog iron ore, decomposes under the deep lower-mantle conditions to form FeO2 and release H2.

Iron oxide - Wikipedia
Iron oxides feature as ferrous (Fe (II)) or ferric (Fe (III)) or both. They adopt octahedral or tetrahedral coordination geometry. Only a few oxides are significant at the earth's surface, particularly wüstite, magnetite, and hematite. Oxides of Fe II. FeO: iron (II) oxide, wüstite. Mixed oxides of Fe II and Fe III.

Equation of state of FeO2 - ScienceDirect
Aug 1, 2018 · The physical properties of FeO 2 were found to be very different from well known pyrite (FeS 2) [3]. In particular Fe is trivalent in FeO 2, but divalent in FeS 2. Moreover, FeO 2 is predicted to be a paramagnetic (bad) metal, neither Curie–Weiss, nor Pauli, while FeS 2 is a diamagnetic insulator.

Oct 11, 2017 · FeO 2 is expected to appear in the Earth’s lower mantle below 1800 km, according to 1 in the pyrite structure, and start to dominate over other Fe oxides at higher pressures. The composition of the mantle is extremely important for the seismology, since it determines convection processes.
