Read MoreIron39s use by humans dates back about 5,000 years. it is the second most abundant metal element in the earth39s crust and is primarily used to produce steel, one of the most important structural materials in the world.
Read MoreBefore getting too deep into the history and modern uses for iron, let39s review the basics
Read MorePure iron is a silver-colored metal that conducts heat and electricity well. iron is too reactive to exist alone, so it only occurs naturally in the earth39s crust as iron ores, such as hematite, magnetite, and siderite.
Read MoreOne of iron39s identifying characteristics is that it is strongly magnetic. exposed to a strong magnetic field, any piece of iron can be magnetized. scientists believe that the earth39s core is made up of about 90 iron. the magnetic force produced by this iron is what creates the magnetic north and south poles.
Read MoreIron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores. the carbon within the wood would have reacted with the oxygen in the ore, leaving behind a soft, malleable iron metal. iron smelting and the use of iron to make tools and weapons began in mesopotamia present-day iraq between 2700 and 3000 bce. over the following 2,000 years, iron smelting knowledge spread eastward into europe and africa during a period known as the iron age.
Read MoreFrom the 17th century, until an efficient method to produce steel was discovered in the mid-19th century, iron was increasingly used as a structural material to make ships, bridges, and buildings. the eiffel tower, constructed in 1889, was made using over 7 million kilograms of wrought iron.
Read MoreIron39s most troublesome characteristic is its tendency to form rust. rust or ferric oxide is a brown, crumbly compound that is produced when the iron is exposed to oxygen. the oxygen gas that is contained in water speeds up the process of corrosion. the rate of rusthow quickly iron turns into ferric oxideis determined by the oxygen content of the water and the surface area of the iron. saltwater contains more oxygen than freshwater, which is why saltwater rusts iron faster than freshwater.
Read MoreRust can be prevented by coating iron with other metals that are more chemically attractive to oxygen, such as zinc the process of coating iron with zinc is referred to as 34galvanizing34. however, the most effective method of protecting against rust is the use of steel.
Read MoreSteel is an alloy of iron and various other metals, which are used to enhance the properties strength, resistance to corrosion, tolerance of heat, etc. of iron. changing the type and amount of the elements alloyed with iron can produce different types of steel.
Read MoreMost iron is produced from ores found near the earth39s surface. modern extraction techniques use blast furnaces, which are characterized by their tall stacks chimney-like structures. the iron is poured into the stacks along with coke carbon-rich coal and limestone calcium carbonate. nowadays, the iron ore normally goes through a process of sintering before entering the stack. the sintering process forms pieces of ore that are 10-25mm, and these pieces are then mixed with coke and limestone.
