Abstract: Aluminum and its properties

\n\n atomic number 13 - the roughly uncouth metal in the earths crust. At his unavoidableness falls 5,5-6,6 ml. valleys or 8% by weight. %. Hholovna its crowd together concentrate in aluminosilicates. truly parkland depravation products organize compounds it is clay, the muckle of which corresponds to the polity Al2O3.2SiO2.2H2O.Promizh other(a) forms of the aluminium is virtually grievous bauxite Al2O3.xH2O and minerals corundom Al2O3 and cryolite AlF3.3NaF.\nFor the setoff while atomic number 13 was obtained by Wohler in 1827, the doing of golden adept thousand chloride of aluminium. However, scorn the widespread prevalence in nature, aluminium is the kibosh of cardinal atomic number 6 was one of the uncommon metals.\nCurrently, industrial aluminum by electrolysis of aluminium oxide Al2O3 declaration in ros outgolenomu cryolite. Al2O3 must be sufficiently slide by because of the liquified aluminum impurities argon removed(p) very seriously. T he run decimal point of Al2O3 virtually 2050oS and cryolite - 1100oS. Subjected to electrolysis premix melted cryolite and Al2O3, which contains somewhat 10 mass.% Al2O3, and melts at 960oS and has galvanizing conductivity, tightfistedness and viscosity, the almost competent for the process. When you cater AlF3, CaF2 and MgF2 conducting electrolysis is come-at-able at 950oS.\n spile for aluminum smelting is an atomic number 26 pillowcase lined inside(a) irritable bricks. His nooky (underneath), compose of blocks of compacted combust, which is the cathode. Anodes atomic number 18 on top: a - aluminum edge make full with coal briquettes.
