Iron oxides are chemical compounds made of iron and oxygen. They are commonly found in nature and come in various forms, such as hematite, magnetite, and goethite. These compounds are important in many industries, including construction and manufacturing, as they are used in pigments, coatings, and even as catalysts in chemical reactions. In addition to their industrial uses, iron oxides play a significant role in the environment. They contribute to soil fertility and are involved in the formation of rust, which occurs when iron reacts with moisture and oxygen. Understanding iron oxides helps us appreciate their impact on both human activities and natural processes.
