• Uses: Industrial uses of iron as carbon steels are numerous and surpass any 410 IRONother alloys. Carbon steels are alloys of iron containing carbon in varying proportions, usually up to 1.7% carbon. Other metals also are incorporated into carbon steels to produce low-alloy steels. Such metals are usually nickel and chromium and are classified as stainless steel, tool steels, and heat-resistant steels. Non-steel iron alloys such as cast iron, wrought iron, nickel iron and silicon iron also have many important applications. Another important application of iron is as an industrial catalyst. It is used in catalyst compositions in the Haber process for synthesis of ammonia, and in Fischer-Tropsch process for producing synthetic gasoline.The followings are some examples of common applications: pharmaceuticals, pesticides, powder metallurgy and so on; as a hot hydrogen generator, gel propellant, combustion activator, catalyst, water cleaning adsorbent, sintered active agent, etc;used for powder metallurgy products, all kinds of mechanical parts and components products, cemented carbide products, etc; as a reducing agent as well as being used for iron salt manufacturing and electronics industry; as nutritional supplements (iron fortifier),for casting,or as reducing agent; in the electronics industry, powder metallurgy. Iron is a mineral used in food fortification that is necessary for the prevention of anemia, which reduces the hemoglobin concentra- tion and thus the amount of oxygen delivered to the tissues. sources include ferric ammonium sulfate, chloride, fructose, glycerophos- phate, nitrate, phosphate, pyrophosphate and ferrous ammonium sulfate, citrate, sulfate, and sodium iron edta. the ferric form (fe3+) is iron in the highest valence state and the ferrous form (fe2+) is iron in a lower valence state. the iron source should not discolor or add taste and should be stable. iron powders produce low discoloration and rancidity. it is used for fortification in flour, baked goods, pasta, and cereal products. Smelting of iron from its ore occurs in a blast furnace where carbon (coke) and limestoneare heated with the ore that results in the iron in the ore being reduced and converted tomolten iron, called “pig iron.” Melted pig iron still contains some carbon and silicon as wellas some other impurities as it collects in the bottom of the furnace with molten slag floatingatop the iron. Both are tapped and drained off. This process can be continuous since moreingredients can be added as the iron and slag are removed from the bottom of the furnace.This form of iron is not very useful for manufacturing products, given that it is brittle andnot very strong.One of the major advances in the technology of iron smelting was the development of theBessemer process by Henry Bessemer (1813–1898). In this process, compressed air or oxygenis forced through molten pig iron to oxidize (burn out) the carbon and other impurities. Steelis then produced in a forced oxygen furnace, where carbon is dissolved in the iron at very hightemperatures. Variations of hardness and other characteristics of steel can be achieved with theaddition of alloys and by annealing, quench hardening, and tempering the steel.Powder metallurgy (sintering) is the process whereby powdered iron or other metals arecombined together at high pressure without high heat to fit molded forms. This process is usedto produce homogenous (uniform throughout) metal parts.One of the most useful characteristics of iron is its natural magnetism, which it loses athigh temperatures. Magnetism can also be introduced into iron products by electrical induction. Magnets of all sizes and shapes are used in motors, atom smashers, CT scanners, and TV and computer screens, toname a few uses. Super magnets can be formed by addingother elements (see cobalt) tohigh-quality iron.Iron is an important element making up hemoglobinin the blood, which carriesoxygen to the cells of ourbodies. It is also very important as a trace element inthe diet, assisting with theoxidation of foods to produce energy. We need about10 to 18 milligrams of ironeach day, as a trace mineral.Iron is found in liver andmeat products, eggs, shellfish, green leafy vegetables,peas, beans, and whole graincereals. Iron deficiency maycause anemia (low red bloodcell count), weakness, fatigue,headaches, and shortness ofbreath. Excess iron in thediet can cause liver damage,but this is a rare condition. Pure iron is very much a laboratory material and finds no great industrial use.
• Description: Carbonyl iron is elemental iron produced by the decomposition of iron pentacarbonyl as a dark gray powder. When viewed under a microscope having a magnifying power of 500 diameters or greater, it appears as spheres built up with concentric shells. It is stable in dry air.
• Physical properties: Pure iron is a silvery-white, hard, but malleable and ductile metal that can be worked andforged into many different shapes, such as rods, wires, sheets, ingots, pipes, framing, and soon. Pure iron is reactive and forms many compounds with other elements. It is an excellentreducing agent. It oxidizes (rusts) in water and moist air and is highly reactive with most acids,releasing hydrogen from the acid. One of its main properties is that it can be magnetized andretain a magnetic field.The iron with a valence of 2 is referred to as “ferrous” in compounds (e.g., ferrous chloride= FeCl2). When the valence is 3, it is called “ferric” (e.g., ferric chloride = FeCl3).Iron’s melting point is 1,535°C, its boiling point is 2,750°C, and its density is 7.873g/cm3.
