Fe2O3, commonly known as iron(III) oxide or ferric oxide, is a chemical compound composed of iron and oxygen. It appears as a reddish-brown powder and is one of the main components of rust. This compound is widely used in various applications, including pigments, ceramics, and as a catalyst in chemical reactions. In nature, Fe2O3 can be found in minerals such as hematite, which is an important source of iron ore. It plays a significant role in the production of iron and steel, as well as in the manufacturing of magnetic materials. Additionally, Fe2O3 is utilized in the production of certain types of glass and as a polishing agent.
