Iron oxide (Cat No.: M048825) refers to a group of compounds composed of iron and oxygen, the most common forms being hematite (Fe₂O₃), magnetite (Fe₃O₄), and wüstite (FeO). These oxides appear in colors ranging from red and brown to black, depending on their composition and oxidation state. Iron oxides are widely used as pigments, catalysts, and in magnetic materials, ceramics, and cosmetics. Their chemical stability, non-toxicity, and magnetic properties make them valuable in environmental, biomedical, and industrial applications, including iron supplements and water treatment.
