Iron Oxide are chemical compounds composed of iron and oxygen. There are sixteen known iron oxide and oxyhydroxides.

Iron oxide and oxide-hydroxides are widespread in nature, play an important role in many geological and biological processes, and are widely utilized by humans, e.g., as iron ores, pigments and catalysts in thermite. Common rust is a form of iron (III) oxide. Iron oxide are widely used as inexpensive, durable pigments in paints, coatings and colored concrete. Colors commonly available are in the “ earthy” end of the yellow/orange/red/brown/black range.


Iron Oxide is a very fine powder of ferric oxide known as “jewelers rouge”, “red rouge”, or simply “rouge”. It is used to put the final polish on metallic jewelry and lenses, and historically as a cosmetic. Rouge is sold as a powder, paste, laced on polishing cloths, or solid bar (with a wax or grease binder). Iron(III) oxide is also used as a pigment in cosmetics. Additionally, Iron oxide are used as pigments in dental composites alongside titanium oxides. Iron Oxide pigments are also used in paints and coatings; color concentrates; and mulch.

Iron oxide dispersant is one of many solutions used to purify water in water treatment facilities. It is considered to be a superior phosphate and zinc stabilizer stressed cooling water systems and an excellent iron and sludge dispersant in boilers.
