Iron in human diet
Unlike the metals that form passivating oxide layers, iron oxides occupy more volume than the metal and thus flake off, exposing fresh surfaces for corrosion. Further refinement with oxygen reduces the carbon content to the correct proportion to make steel. Look up nutrition info for over 8,000 foods and compare foods side-by-side. Pure iron is relatively soft, but is unobtainable by smelting because it is significantly hardened and strengthened by impurities, in particular carbon, from the smelting process. Use ctrl-W or ctrl-F4 to close popup windows. Its abundance in rocky planets like Earth is due to its abundant production by fusion in high-mass stars, where it is the last element to be produced with release of energy before the violent collapse of a supernova, which scatters the iron into space. Track your foods and physical activities to see how they stack up. The mechanical properties of iron and its alloys can be evaluated using a variety of tests, including the Brinell test, Rockwell test and the Vickers hardness test. Iron metal has been used since ancient times, although copper alloys, which have lower melting temperatures, were used even earlier in human history. Crude iron metal is produced in blast furnaces, where ore is reduced by coke to pig iron, which has a high carbon content. To close a submenu without making a selection, use the Escape key. It is a metal in the first transition series.

Elemental iron occurs in meteoroids and other low oxygen environments, but is reactive to oxygen and water. Iron oxide mixed with aluminium powder can be ignited to create a thermite reaction, used in welding and purifying ores. Iron forms binary compounds with the halogens and the chalcogens. Among its organometallic compounds is ferrocene, the first sandwich compound discovered. Steels and iron alloys formed with other metals ( alloy steels ) are by far the most common industrial metals because they have a great range of desirable properties and iron-bearing rock is abundant. Fresh iron surfaces appear lustrous silvery-gray, but oxidize in normal air to give hydrated iron oxides, commonly known as rust. Get tips and support to help you make healthier choices and plan ahead. Track the foods you eat and compare to your nutrition targets. Iron is also the metal at the active site of many important redox enzymes dealing with cellular respiration and oxidation and reduction in plants and animals. To open the dropdown menus, use left or right arrow to open, and Tab key to navigate in. Iron is a chemical element with symbol Fe (from Latin: ferrum ) and atomic number 26.
