History
Aluminum is the third most abundant element on the Earth and mass of this element represents 8,8 percent from the it`s crust. In the history of use as the metal came relatively late, only in the 19 century, when scientists were able to produce it from the compound. The first metallic aluminum in 1825 was received by famous Danish physicist Hans Christian Ersted. In 1855, the World Exhibition in Paris was shown the first ingot of aluminum, obtained by the French chemist Henri Etienne Sainte-Claire Devil. Production this metal increased with the development of the construction industry. Since 1855 the cost of aluminum fell to a few thousand times. In 1903 was developed by the alloy of aluminum and copper, called duralumin.
Nowadays
In our time, aluminum is one of constructional materials. Big importance has its use in aircraft, where it irreplaceable because of it lightness, strength, flexibility. Also aluminum is used in the so-called alyuminotermiya. Russian scientist Beketov discovered new way in 1865, by that method other metals could be isolate from its oxides. Nowadays this method is used in producing such metals like chrome, vanadium, manganese. There are few specific applications of aluminum, for example, it is used as additive in propellant as powder. Russian missile “Saturn” burns 36 tons such propellant during the flying.
