Ferrous is an adjective derived from the Latin word ''ferrum'' ( Iron ). The term is commonly used to indicate the presence of, or having to do with, iron, most commonly in Metallurgy or related industries. CHEMISTRY In Chemistry , ferrous is reserved for iron with Oxidation Number of +2 (denoted Fe2+), whereas Ferric indicates that it has Oxidation Number of +3 (denoted Fe3+). Current IUPAC nomenclature specifies ''Iron (II)'' in place of the term ferrous in chemical names. Ferrous Oxide (FeO) is black in color and the main constituent of the mineral Wüstite . Ferrous compounds are easily oxidized further to Ferric compounds. OTHER USES Ferrous in non-chemical contexts is a general adjective for iron. For example, referring to "ferrous metallurgy" includes the production of Metal lic iron, including Wrought Iron (commercially pure iron, with less than 0.2% carbon), Cast Iron (with 3.5-5% carbon), Steel (with a carbon content between them), or other Alloy ing elements. It is common for ferrous materials to be highly Magnetic , although not all of them are. Different types of iron and steel are more or less magnetic. High- Chromium Stainless Steel is nearly non-magnetic, while pure iron tends to form magnets easily. Some impurities allow iron to retain its magnetism longer than pure iron magnets. SEE ALSO |
