Ferric oxide

Ferric oxide is a chemical compound composed of iron and oxygen, commonly known as rust when it forms on iron or steel. It has a reddish-brown color and is often used as a pigment in paints, coatings, and ceramics due to its durability and vibrant hue. Ferric oxide also appears in various industrial applications, such as in magnetic materials for recording media and as a catalyst in chemical processes. It is stable, non-toxic, and naturally occurring, making it a common material in both industrial and environmental contexts.
