Iron Oxide II, also known as ferrous oxide or FeO, is a chemical compound composed of iron and oxygen. It appears as a black crystalline powder and is one of several iron oxides, distinct from the more common red iron oxide (Fe₂O₃) or magnetic iron oxide (Fe₃O₄). FeO forms under low-oxygen conditions, often in industrial processes or geological settings. Its unique properties make it valuable in specific applications, though it is less stable than other iron oxides.

Key characteristics of Iron Oxide II include its ionic structure, high melting point (around 1,377°C), and tendency to oxidize in air, gradually converting to Fe₃O₄ or Fe₂O₃. This reactivity requires careful handling and storage in inert environments. FeO is insoluble in water but reacts with acids, forming ferrous salts. Its magnetic properties are weaker compared to magnetite, limiting its use in magnetic applications.

Industrially, Iron Oxide II serves roles in steel production, acting as a raw material for alloys, and in pigments for ceramics or coatings. It also functions as a catalyst in chemical reactions, such as ammonia synthesis. Recent research explores its potential in nanotechnology and biomedical fields, including drug delivery systems, due to its biocompatibility and controlled reactivity.

Safety precautions are essential when handling FeO. Inhalation of dust may irritate the respiratory tract, and contact with skin or eyes should be avoided. Proper protective equipment and ventilation are recommended. Storage in sealed, oxygen-free containers prevents degradation.

Though less prominent than other iron oxides, Iron Oxide II remains crucial in specialized industries. Its reactivity and unique properties drive innovation in materials science, underscoring its importance despite stability challenges. Understanding its behavior ensures safe and effective utilization across diverse applications.
