Descripción

General description

Iron(II) oxide nanoparticles possess unique properties such as superparamagnetic behavior, ease of surface modification, and biocompatibility. They are applied in the fields of photocatalysis, magnetic storage media, targeted drug delivery, and gas sensing.

Iron(II) oxide, also known as ferrous oxide or wustite, is a chemical compound with the formula FeO. It is a fine, grey-black powder with a 10-mesh particle size. Iron(II) oxide adopts a cubic, rock salt structure and often exists as a non-stoichiometric, iron-deficient compound in which some of the iron is oxidized to a 3+ oxidation state. Iron(II) oxide is shelf-stable at room temperature but at 575 °C tends to disproportionate to iron metal and Fe₃O₄. One of its primary applications is as a black pigment in paints, inks, and ceramics.
