Iron Oxide Chemical Appearance

Iron Oxide has the appearance Fe2O3 of a red brown solid.

Chemical Applications and Strengths

Iron Oxide is an extremely efficient chemical compound and therefore, has many commercial applications. Its main applications and strengths are:

• Manufacturers primarily use Fe2O3 as a feedstock in the iron and steel industries to produce iron, steel, and other alloys on a large scale.

  Manufacturers produce a fine powder of Fe2O3 , known as rouge, which they use to polish metallic jewelry and lenses. The cosmetic industry also uses rouge in certain cosmetic products.

  Rouge cuts more slowly than modern polishing compounds, but it remains widely used because it provides a superior finish.

  Manufacturers extensively use Fe2O3 as a pigment, and regulatory authorities approve certain Iron Oxide pigments for use in cosmetics.

  Manufacturers use Iron Oxide as a pigment in dental composites, often alongside titanium dioxide.

  The Swedish paint color Falu red uses hematite as an essential pigment component.

  Manufacturers use Fe2O3 in magnetic recording applications. Its magnetic properties make it suitable for magnetic storage and recording media, including magnetic disks and tapes.

  Researchers and manufacturers also use Iron Oxide in photocatalysis, including as a photoanode material for solar water oxidation.

  The pharmaceutical and personal-care industries also use Iron Oxide in certain products. For example, calamine lotion contains a combination of zinc oxide and Fe2O3 . Fe2O3 acts as an antipruritic ingredient that helps relieve itching.
