Because steel is a mixture rather than a chemical compound, steel does not have a set chemical compound formula. The naming convention for steel depends upon the steel's composition—what is mixed in with the iron—such as carbon steel or tungsten steel.

Chemistry ch. 2. Iron ore is heterogenous mixture that contains iron oxide. Iron ore can be smelted to produce pure iron.

Compounds. Three oxygen compounds of iron are known: ferrous oxide, FeO; ferric oxide, Fe 2 O 3; and ferrosoferric oxide, or ferroferric oxide, Fe 3 O 4, which contains iron in both +2 and +3 oxidation states. Ferrous oxide is a greenish to black powder used primarily as a pigment for glasses.

Ferrous cation. Iron is a chemical element with the symbol Fe and atomic number 26. Iron makes up 5% of the Earth's crust and is second in abundance to aluminium among the metals and fourth in abundance among the elements. Physiologically, it. exists as an ion in the body. Iron (as Fe2+, ferrous ion) is a necessary trace element used by all known living organisms.

What is Iron Ore? Earth's most important iron ore deposits are found in sedimentary rocks. They formed from chemical reactions that combined iron and oxygen in marine and fresh waters. The two most important minerals in these deposits are iron oxides: hematite (Fe2O3) and magnetite (Fe3O4). These iron ores have been mined to produce almost every iron and steel object that we use today from .

Dec 05, 2008· Best Answer: Iron is an element, not a compound, therefore does not have a chemical formula. It's Chemical symbol is Fe. However, Iron has several different oxidation forms that have differently charged atoms. Both Iron II, with a +2 charge, and Iron III, with a +3 charge, are common.

The shape and physical characteristics of iron and steel slag are similar to ordinary crushed stone and sand, however due to differences such as the chemical components and cooling processes, it is possible to provide different types of slag with a wide variety of unique properties.
