Black iron oxide

Black iron oxide, also known as magnetite or lodestone, is a naturally occurring mineral composed of iron and oxygen. It appears as a dark, black to grayish-black substance and has magnetic properties, meaning it can attract iron and other ferromagnetic materials. It is often used as a pigment in paints and coatings to provide a durable, opaque black color, and in magnetic applications. Its stability, resistance to weathering, and magnetic qualities make it valuable in industrial and scientific uses. Overall, black iron oxide is a stable, naturally occurring mineral with important applications across various industries.
