Rust is an iron oxide‚ usually red oxide formed by the redox reaction of iron and oxygen in the presence of water or air moisture. Several forms of rust are distinguishable both visually and by spectroscopy‚ and form under different circumstances.Rust consists of hydrated iron(III) oxides Fe2O3·nH2O and iron(III) oxide-hydroxide (FeO(OH)‚ Fe(OH)3). Given sufficient time‚ oxygen‚ and water‚ any iron mass will eventually convert entirely to rust and disintegrate. Surface rust is flaky and friable‚
