Iron Oxide (Fe2O3)

Iron(III) oxide, or Fe₂O₃, is a common chemical compound made of iron and oxygen. It appears as a reddish-brown solid, often called rust, which forms when iron reacts with water and oxygen over time. Iron oxide is used in various applications, including pigments for coloring, polishing compounds, and in the production of iron and steel. It is stable, non-toxic, and naturally occurring, playing a key role in both industrial processes and natural environments. The compound's properties make it an important material in science and manufacturing.
