    4 Ways to Make Iron Oxide - wikiHow

    Jun 03, 2011  To make iron oxide, start by getting an iron source with as much exposed surface area as possible, like steel wool. Then, choose an oxidizing agent, such as hydrogen peroxide, bleach, or salt water. Next, submerge the iron source in the oxidizing agent and wait for it to yield rust, which can take anywhere from several hours to a week depending ...

    Iron Oxide - an overview ScienceDirect Topics

    J. Wollschläger, in Encyclopedia of Interfacial Chemistry, 2018 Abstract. Iron oxide films can show very different stoichiometries due to the flexibility of their Fe oxidation state (Fe 2 +/Fe 3 +).This flexibility is accompanied by the formation of various single-crystalline phases (e.g., hematite, magnetite, maghemite, and wüstite) with different chemical and physical properties.
