  3. Aluminium sulfate - Wikipedia

    en.wikipedia.org/wiki/Aluminium_sulfate

    Aluminium sulfate may be used as a deodorant, an astringent, or as a styptic for superficial shaving wounds. [citation needed] Aluminium sulfate is used as a mordant in dyeing and printing textiles. It is a common vaccine adjuvant and works "by facilitating the slow release of antigen from the vaccine depot formed at the site of inoculation."

    en.wikipedia.org/wiki/Aluminium_compounds

    Aluminium (British and IUPAC spellings) or aluminum (North American spelling) combines characteristics of pre- and post-transition metals. Since it has few available electrons for metallic bonding, like its heavier group 13 congeners, it has the characteristic physical properties of a post-transition metal, with longer-than-expected interatomic ...

    en.wikipedia.org/wiki/Hall–Héroult_process

    The Hall–Héroult process is the major industrial process for smelting aluminium.It involves dissolving aluminium oxide (alumina) (obtained most often from bauxite, aluminium's chief ore, through the Bayer process) in molten cryolite and electrolyzing the molten salt bath, typically in a purpose-built cell.

    Aluminum sulfate, or "alum" as it is commonly referred, has been found to be an effective lake management tool by reducing the phosphorus load. [2] Sediment core sampled from a Minnesota lake. Aluminum sulfate flocs are depicted as white clumps near the sediment surface. Alum was first applied in 1968 to a lake in Sweden. [2]

    Ettringite is the most common and prominent member of the AFt group (X in this case denoting sulfate), and often simply called Alumina Ferrite tri-sulfate (AFt). AFm: abbreviation for "alumina, ferric oxide, mono-substituted" or (Al 2 O 3 − Fe 2 O 3 − mono). It represents another group of calcium aluminate hydrates with general formula [Ca ...

  8. Aluminium–scandium alloys - Wikipedia

    en.wikipedia.org/wiki/Aluminium–scandium_alloys

    Aluminium–scandium alloys (AlSc) are aluminum alloys that consist largely of aluminium (Al) and traces of scandium (Sc) as the main alloying elements.In principle, aluminium alloys strengthened with additions of scandium are very similar to traditional nickel-base superalloys in that both are strengthened by coherent, coarsening resistant precipitates with an ordered L1 2 structure.

  9. Aluminium sulfacetate - Wikipedia

    en.wikipedia.org/wiki/Aluminium_sulfacetate

    It is an evenly balanced mixture of aluminium sulfate and aluminium acetate.It can be used as a mordant, which is a substance used to set dyes on fabrics [3] that typically contains a polyvalent metal ion like aluminium or iron, [4] In mixtures with basic aluminium diacetate or aluminium sulfacetate, aluminium triacetate has been used as a mordant with alizarin dye.
