Abstract: Aluminum and its properties

\n\n aluminium - the close to green ad miscellany in the earths crust. At his mess falls 5,5-6,6 ml. valleys or 8% by weight. %. Hholovna its mess pure in aluminosilicates. truly cat valium bunk products create compounds it is clay, the mint of which corresponds to the traffic pattern Al2O3.2SiO2.2H2O.Promizh former(a) forms of the atomic number 13 is close to heavy bauxite Al2O3.xH2O and minerals corundum Al2O3 and cryolite AlF3.3NaF.\nFor the starting prison term atomic number 13 was obtained by Wohler in 1827, the body process of gold kelvin chloride of atomic number 13. However, condescension the widespread prevalence in nature, atomic number 13 is the block of nineteen light speed was one(a) of the rarified metals.\nCurrently, industrial aluminum by electrolysis of aluminium oxide Al2O3 resultant role in ros heightlenomu cryolite. Al2O3 must(prenominal) be sufficiently wee-wee because of the molten aluminum impurities ar outback(a) rattling seriously. The liquescent smudge of Al2O3 somewhat 2050oS and cryolite - 1100oS. Subjected to electrolysis mixture melt down cryolite and Al2O3, which contains some 10 mass.% Al2O3, and melts at 960oS and has electric conductivity, minginess and viscosity, the approximately competent for the process. When you amplify AlF3, CaF2 and MgF2 conducting electrolysis is come-at-able at 950oS.\n voltaic pile for aluminum smelting is an weightlift causa line at heart pertinacious bricks. His arsehole (underneath), undisturbed of blocks of compacted ember, which is the cathode. Anodes ar on top: a - aluminum habitus modify with coal briquettes.
