In essence, iron oxide, Fe 2O 3, is reduced with with carbon (as coke) although in the furnace the actual reducing agent is probably carbon monoxide, CO. Most chemistry text books cover the blast furnace process. Nearly all iron produced commercially is used in the steel industry and made using a blast furnace. Other routes to small samples of pure iron include the reduction of iron oxide, Fe 2O 3, with hyrogen, H 2. The Fe(CO) 5 is a volatile oily complex which is easily flushed from the reaction vessel leaving the impurities behind. The carbonyl decomposes on heatingto about 250☌ to form pure iron powder. The intermediate in this process is iron pentacarbonyl, Fe(CO) 5. Small amounts of pure iron can be made through the purification of crude iron with carbon monoxide. Isolation: it is not normally necessary to make iron in the laboratory as it is available commercially. This sample is from The Elements Collection, an attractive and safely packaged collection of the 92 naturally occurring elements that is available for sale. Do not attempt this reaction unless are a professionally qualified chemist and you have carried out a legally satisfactory hazard assessment. The picture above shows the result from adding iron filings to a burning mixture of potassium chlorate and sucrose. Iron filings salts cause sparks in flames. Iron metal is a silvery, lustrous metal which has important magnetic properties. The pure metal is very reactive chemically, and rapidly corrodes, especially in moist air or at elevated temperatures. The pure metal is not often encountered in commerce, but is usually alloyed with carbon or other metals. Iron is a vital constituent of plant and animal life, and is the key component of haemoglobin. It is found in the sun and many types of stars in considerable quantity. Iron sulfate (FeSO 4) is used to treat the blood disease anemia.Įstimated Crustal Abundance: 5.Iron is a relatively abundant element in the universe. Iron plays a role in the creation of chlorophyll in plants and is an essential part of hemoglobin, the substance that carries oxygen within red blood cells. In addition to helping build the world around us, iron helps keep plants and animals alive. Steel is used to make paper clips, skyscrapers and everything in between. Small amounts of chromium improves durability and prevents rust (stainless steel) nickel increases durability and resistance to heat and acids manganese increases strength and resistance to wear molybdenum increases strength and resistance to heat tungsten retains hardness at high temperatures and vanadium increases strength and springiness. The addition of other elements can give steel other useful properties. Steel typically contains between 0.3% and 1.5% carbon, depending on the desired characteristics. Huge amounts of iron are used to make steel, an alloy of iron and carbon.
