Aluminum is a metal that is most abundant element after oxygen in the earth's crust, where it has about 8%. She first appeared in 1855g at an exhibition in Parizu.Danas is the only steel used by more than aluminum.
Alumina belongs to the group of light metala.Dobija from bauxite ore (containing about 50% Al), which is processed into aluminum oxide Al2O3, which is removed from the electrolysis whereby consumes much electricity 16kWh / kg Al.
Bauxite reactor is a mixture of aluminum hydroxide (Al2O3, reactor H2O or 3H2O) with admixtures of silicon dioxide, iron oxide, titanium oxide, etc. The technical practices usually differ red bauxite with a little silica and a white bauxite with a lot of silica. Technical value of bauxite reactor in an increase which contains less silicon and titanium oxide.
To obtain 1t aluminum should be 2t alumina or bauxite 5t, at current consumption 15000-20000 kWh, which is a very expensive process of obtaining aluminum. Aluminium is mainly used for the production of alloys and little in pure satnju for high voltage power lines.
It is resistant to acid except hydrochloric or is poorly resistant to baza.U seawater aluminum is quickly destroyed.
