Conductivity in iron oxides

Iron production from Fe3O4 and graphite by applying 915MHz microwaves

“…:7, m FeO ðrÞ¼ 0:2, d is the skin depth [10][11][12]. This indicates that the ohmic loss will be higher in the wustite phase (FeO¼Feþ1/2O 2 ).…”

Investigations of a Cretaceous limestone with spectral induced polarization and scanning electron microscopy

“…The amount of ferrous iron in relation to the total iron content in glauconite is usually in the range 10-20 per cent, but the ratio is also dependent on the redox conditions (McRae 1972;Fanning 1989). Iron oxides in the ferrous state (magnetite and wüstite) have high conductivity and can thus produce high IP effects (Bertin & Loeb 1976), while iron oxides in the ferric (oxidized) state (hematite) have lower conductivity values (Tannhauser 1962;Vella & Emerson 2012). It is known from the Härlöv core that glauconitic sand is present at different levels throughout the limestone.…”

Fabrication of rechargeable lithium ion batteries using water-based inkjet printed cathodes

“…Introduced Fe 2 O 3 can cause the energy loss by the consumption of active materials and lower the conductivity of the entire ink and electrodes due to its low electrical conductivity and electrochemical performance [19,20]. According to these two reactions mentioned above, we could expect fewer impurities in sample D because of less consumption of protons and hydroxide ions compared with other samples.…”
