Magnesium, a silvery white metal that is in appearance similar to aluminum, is the eight most abundant element in the Earth’s crust (about 2.5 percent). Its density of only two thirds of aluminum’s is making it the lightest structural metal known, however in its pure form it lacks sufficient strength for most structural application.
At high temperatures (650 °C; 1190 °F) is strongly reactive with oxygen, and in dry air it burns with bright white light and intense heat.
Magnesium is about one-sixth as plentiful as potassium in human body cells, however it is required as a catalyst for enzyme reactions in carbohydrate metabolism. Lack of magnesium can produce severe health problems like kidney disease, weakness and dizziness.
Also in nature, it does not occur in its free form. It was known in compounds and was first isolated in 1808 by Sir Humphrey Davis, who evaporated the mercury from a magnesium amalgam made by electrolyzing a mixture of moist magnesia and mercuric oxide.
Occurrence and uses
Magnesium is usually distributed in minerals such as magnesite, dolomite, burcite, serpentine, chrysolite, meerschaum, talc, and most kinds of asbestos. Also seawater contains about 0.13 percent magnesium, mostly as the dissolved chloride.
Therefore is now commercially produced by electrolysis of molten magnesium chloride (MgCl2), obtained from seawater by reducing of its compounds by with suitable reducing agents.
Its low structural strength is preventing it to be used in pure form, but the addition of alloying
