(or see spelling differences) is a chemical element in the boron group with symbol Al and atomic number 13. It is a silvery white, soft, ductile metal. Aluminium is the third most abundant element (after oxygen and silicon), and the most abundant metal in the Earth\'s
is an excellent conductor of heat and electricity. Its thermal conductivity is about one-half that of its electrical conductivity, about two-thirds. It crystallizes in the face-centred cubic structure. All natural aluminum is the stable isotope aluminum-27. Metallic aluminum and its oxide and hydroxide are
chemical processing of the aluminum itself. As we talked about in Update 4 on Steellurgy,lurgists spend a good portion of their working lives manipulating the chemistry and internal structure ofs to achieve better properties of the
Aluminum has high reflectivity and can be used for decorative applications. Some aluminum alloys can match or even exceed the strength of common construction steel. Aluminum retains its toughness at very low temperatures, without becoming brittle like carbon steels. Aluminum is a good conductor of heat and
Bauxite is a naturally occurring, heterogeneous material composed primarily of one or more aluminum hydroxide minerals, plus various mixtures of silica, iron oxide, titania, aluminosilicate, and other impurities in minor or trace amounts. The principal aluminum hydroxide minerals found in varying proportions with bauxites are gibbsite and the polymorphs boehmite and
is often selected for its electrical conductivity, which is nearly twice that of copper on an equivalent weight basis. The requirements of high conductivity and mechanical strength can be met by use of long-line, high-voltage, aluminum steel-cored reinforced transmis-sion cable. The thermal conductivity of aluminum alloys, about 50 to

Aluminum phosphide is a dark gray or dry, yellow, crystalline solid. It reacts with moisture to give phosphine, a flammable and poisonous gas.Normally, phosphine will spontaneously ignite upon contact with air. If there is an excess of water, the phosphine fire will not normally ignite any surrounding combustible

Tris(8-hydroxyquinoline)aluminum(III), commonly known as Alq 3, is widely used in organic light-emitting diodes (OLEDs) as an electron-transport material (ETM) and emitting layer material (ELM) due to its high thermal stability, high quantum yield of fluorescence and high electron-transport ability.. Alq 3 as the electron-transport and emitting layer material was the first efficient low
structure and bonding of aluminum oxide clusters, AlxOy are studied with anion photoelectron spectroscopy and are compared with preliminary ab initio calculations. The spectra were obtained at four detachment photon

Aluminum\'s name is derived from alumina, the mineral from which Sir Humphrey Davy attempted to refine it from in 1812. It wasn\'t until 1825 that Aluminum was first isolated by Hans Christian Oersted. Aluminum is a silvery gray metal that possesses many desirable characteristics. It is light, nonmagnetic and
Aluminum Nitride Description. Aluminum nitride is a refractory compound ceramic material with a hexagonal wurtzite structure. Pure aluminum nitride has a blue-white color, and aluminum nitride ceramics are usually gray or
