Uses

The most industrially-important iron ores are chemically iron oxides. Some iron oxides are widely used in ceramic applications, particularly in glazing. Many metal oxides provide the colors in glazes after being fired at high temperatures.
Iron oxides yield pigments (see iron oxide pigments). Natural iron oxides pigments are called ochres. Many classic paint colors, such as raw and burnt siennas and umbers, are iron-oxide pigments. These pigments have been used in art since the earliest prehistoric art known, the cave paintings at Lascaux and nearby sites. Iron (III) oxide is typically used.Iron pigments are widely used in the cosmetic field. They are considered to be nontoxic, moisture resistant, and nonbleeding. Iron oxides graded safe for cosmetic use are produced synthetically in order to avoid the inclusion of ferrous or ferric oxides, and impurities normally found in naturally occurring iron oxides. Typically, the iron(II) oxide pigment is black, while the iron(III) oxide is red or rust-colored.
Black oxide converts ferrous materials into magnetite for corrosion resistance purposes. A grade of hematite called MIO (micaceous iron oxide) is used as anti-corrosion paint (many bridges, Eiffel tower).Iron oxide is used in magnetic recording, recording sound, pictures, video and computer data on plastic tape or floppy disks.
Iron oxide (CAS NO.11115-92-7) are used as contrast agent in Magnetic Resonance Imaging, to shorten proton relaxation times, (T1, T2 and T2*). The superparamagnetic contrast agents are composed of a water insoluble crystalline magnetic core, usually magnetite (Fe₃O₄) or maghemite (γ-Fe₂O₃). The mean core diameter ranges from 4 to 10 nm. This crystalline core is often surrounded by a layer of dextran or starch derivatives. The total size of the particle is expressed as the mean hydrated particle diameter. USPIO, Ultrasmall Superparamagnetic Iron Oxide nanoparticles, which usually have single crystal cores, have a mean hydrated particle diameter less than 50 nm.They may also be used in electrochromic paints.Combined with aluminium powder, iron oxide forms thermite.The iron oxide cycle (Fe₃O₄/FeO) is a two-step thermochemical process used for hydrogen production.
