Ferrous oxide

Ferrous oxide, also known as iron(II) oxide, is a chemical compound made of iron and oxygen. It appears as a black or dark brown solid and is commonly found in nature as a mineral called wüstite. This compound forms when iron reacts with oxygen in environments with limited oxygen supply, often during corrosion or rusting processes. Ferrous oxide is used in various industrial applications, including the manufacturing of steel, ceramics, and as a pigment. Its properties are important in understanding iron's behavior in different environmental and industrial contexts.
