OverviewOxidesHydroxidesMicrobial degradationEnvironmental effectsSee alsoExternal linksIron oxides are chemical compounds composed of iron and oxygen. There are sixteen known iron oxides and oxyhydroxides, the best known of which is rust, a form of iron III oxide. Iron oxides and oxyhydroxides are widespread in nature and play an important role in many geological and biological processes. They are used as iron ores, pigments, alysts, and in thermite, and occur in hemoglobin.

Iron III oxide - Wikipedia

Iron III oxide or ferric oxide is the inorganic compound with the formula Fe 2 O 3.It is one of the three main oxides of iron, the other two being iron II oxide FeO , which is rare; and iron II,III oxide Fe 3 O 4 , which also occurs naturally as the mineral magnetite.As the mineral known as hematite, Fe 2 O 3 is the main source of iron for the steel industry.

Why Does My Soldering Iron Tip Turn Black How to Clean it

Oxidation is the natural process by which metals break down in interaction with oxygen and moisture. In the presence of normal air, at normal temperatures, iron slowly turns into iron oxide, a dark, brittle substance. The transformation happens gradually, in layers, from the outside in – this is why old iron tools and structures turn brown and disintegrate over time. High heat dramatically ...
