Iron Powder (Fe)

Iron is a chemical element with the symbol Fe (from the Latin: Ferrum) and the atomic number 26. It is a metal in the first transition series. It is in mass the most common element on Earth, forming a large part of the outer and inner core of the Earth. It is the fourth most common element in the earth’s crust. Its abundance in rocky planets such as the Earth is due to its abundant production by fusion into stars of great mass, where it is the last element that occurs with the release of energy before the violent collapse of a supernova, which disperses the iron in the space.

As in the other elements of group 8, ruthenium, and osmium, iron exists in a wide range of oxidation states, from -2 to +7, although the most common are +2 and +3. Elemental iron is produced in meteoroids and other environments with low oxygen content but is reactive to oxygen and water. The fresh iron surfaces have a brilliant silver-gray color but are oxidized in normal air to give hydrated iron oxides, commonly known as rust. Unlike metals that form passive oxide layers, iron oxides take up more volume than metal and then come off, exposing fresh surfaces to corrosion.

Metal iron has been used since ancient times, although copper alloys, which have lower melting temperatures, have been used earlier in the history of mankind. Pure iron is relatively soft, but can not be obtained by casting because it is noticeably hardened and reinforced by impurities, in particular, carbon, by the melting process. A certain percentage of carbon (between 0.002% and 2.1%) produces steel, which can be up to 1000 times more difficult than pure iron. Raw metal iron is produced in blast furnaces, where coke is reduced to raw iron ore, which has a high carbon content. Further refining with oxygen reduces the carbon content to the correct ratio to produce steel. Steel and iron alloys made of other metals (alloy steels) are by far the most common industrial metals because they have a wide variety of desirable properties and the rock containing iron is abundant.
