![]() ![]() The Iron Age began in the Mediterranean and Eastern Europe around 1200 BCE, though it only spread to Asian regions closer to 600 BCE. While it was occasionally used prior in history, Iron was popularized during the Iron Age (1200 BCE – 600 BCE), the third leg of the Stone-Bronze-Iron Age progression. Historians and archaeologists believe that the element iron has been used for around five thousand years. When and How was Iron Discovered? The History of Iron Furthermore, magnetite is used in Gas-to-Liquid (GTL) processes which turn natural gas into synthetic fuel. Iron speeds up a reaction between hydrogen and nitrogen to produce ammonia, a common large-scale industrial process. Specifically, magnetite, an iron-oxide, is used as a catalyst in the Haber-Bosch process. Iron as a CatalystĪctivated or promoted iron is also used as a catalyst in a variety of chemical industries. Steel is used for buildings, infrastructure, machines, metal stamping, fabrication, and so much more – like steel wool, which is mostly pure iron with a little carbon added. stone, wood, and brick, with less material and low cost. Iron and its alloys are used in a wide array of manufacturing industries, forming key structural components in vehicles, buildings, ships, and other appliances The element iron can support larger and stronger structures than other building materials, i.e. As a key alloying agent, iron is used as a base in the manufacturing of steel, sheet iron, cast iron, and wrought iron. The element iron is crucial in architectural and structural design. Iron Applications in Today’s World What is the Element Iron Used For? Structural Uses of Iron For instance Bismuth in steel improves machinability, Silicon increases magnetic properties. Depending on the major alloying agent in alloy steel, the metal can have varying chemical properties. Ferroalloys aren’t suitable for independent use rather, because of their low melting points, they are added to liquid steel to form alloy steel. Iron is the major alloying agent in ferroalloys, a classification of alloys with less than 50% iron and a high concentration of silicon, manganese, aluminum, nickel, chromium, molybdenum, vanadium, or other elements. Iron and carbon form the well-known alloy of steel. In plants, iron is necessary for the production of chlorophyll. The U.S Daily Recommended Allowance is 18 milligrams of iron. Too little iron in animals can lead to anemia, while excess iron can be toxic and damaging to the body. Iron is also present in myoglobin, the muscle cells which stores and transports oxygen. In animals, iron is used to make hemoglobin, a protein in red blood cells responsible for the transportation of oxygen from the lungs to the rest of the body. The element iron is an essential mineral for all living organisms. Iron’s electronegativity is 1.83 on the Pauling scale. Iron’s electron configuration is 3d6 4s2, and thus it has 2 valence electrons. As a transition metal, iron is located in the d-block, specifically in group 8 and period 4. Iron’s element symbol is Fe, and has an atomic number of twenty six. The Iron Range is a collection of iron-mining regions neighboring Lake Superior.Iron is used to create sparks in fireworks.Research shows that Mars’ mantle constitutes twice as much iron as Earth’s, and that the planet’s reddish color is actually rust on Mars’ surface.Iron can be recycled, with tremendous environmental benefits.Pure iron is actually quite soft and ductile like most metals – the addition of carbon and heat rigidifies the iron.The earth’s inner core is believed to be made up primarily of iron and nickel.Iron is the second most abundant metal on earth, second to aluminum.The element symbol ‘Fe’ comes from iron’s Latin name ‘ferrum,’ meaning ‘firmness.’.Under a flame test, iron burns a brilliant gold color.Iron readily reacts with both oxygen and water to form iron(III)oxide, or ferric oxide, commonly known as rust, in following unbalanced reaction: Fe + O 2 + H 2O → Fe 2O 3H 2O.Iron also plays an important role in the bodies of living organisms, and is even responsible for the red color of our blood. It has incredibly strong alloys which are used in diverse areas of manufacturing, construction, and electronics. ![]() The element iron is a ductile, silver-gray metal that is very reactive with the air around us. ![]()
