Aluminium example sentences

Aluminium and its alloys can be given shapes of pipe, tubes, rods, wires, plates or foils and, therefore, find uses in packing, utensil making, construction, aeroplane and transportation industry.The use of aluminium and its compounds for domestic purposes is now reduced considerably because of their toxic nature.He left the gap under aluminium and a gap under silicon, and called these elements Eka- Aluminium and Eka-Silicon.It is a powerful reducing agent and reduces almost all metal oxides other than those of the alkali and alkaline earth metals, aluminium and a few transition metals.Bauxite, Al2O 2H2O and cryolite, Na3AlF6 are the important minerals of aluminium.The outer electronic configureuration of these elements is ns2np A close look at the electronic configureuration suggests that while boron and aluminium have noble gas core, gallium and indium have noble gas plus 10 d-electrons, and thallium has noble gas plus 14 f- electrons plus 10 d-electrons cores.Aluminium and gallium oxides are amphoteric and those of indium and thallium are basic in their properties.Though, several ores contain aluminium, it is from bauxite, a clay-like substance that alumina and later aluminium is obtained.Aluminium is an important metal because it combines the strength of metals such as iron, with extreme lightness and also with good conductivity and great malleability.Industries manufacturing aluminium, zinc and copper produce mud and tailings.Boron does not react with acids and alkalies even at moderate temperature; but aluminium dissolves in mineral acids and aqueous alkalies and thus shows amphoteric character.Aluminium is used extensively in industry and every day life.Boron is a typical non-metal, aluminium is a metal but shows many chemical similarities to boron, and gallium, indium and thallium are almost exclusively metallic in character.Aluminium, calcium, silica, iron, magnesium are the major elements of amphiboles.Consequently, the atomic radius of gallium (135 pm) is less than that of aluminium (143 pm).
