  3. Aluminium oxide - Wikipedia

    en.wikipedia.org/wiki/Aluminium_oxide

    Aluminium oxide (or aluminium(III) oxide) is a chemical compound of aluminium and oxygen with the chemical formula Al 2 O 3. It is the most commonly occurring of several aluminium oxides, and specifically identified as aluminium oxide. It is commonly called alumina and may also be called aloxide, aloxite, or alundum in various forms and ...

  6. Molar mass - Wikipedia

    en.wikipedia.org/wiki/Molar_mass

    Molecular weight (M.W.) (for molecular compounds) and formula weight (F.W.) (for non-molecular compounds), are older terms for what is now more correctly called the relative molar mass (M r). [8] This is a dimensionless quantity (i.e., a pure number, without units) equal to the molar mass divided by the molar mass constant. [notes 1]

  7. Alum - Wikipedia

    en.wikipedia.org/wiki/Alum

    An alum (/ ˈ æ l ə m /) is a type of chemical compound, usually a hydrated double sulfate salt of aluminium with the general formula X Al(SO 4) 2 ·12 H 2 O, such that X is a monovalent cation such as potassium or ammonium. [1] By itself, "alum" often refers to potassium alum, with the formula KAl(SO 4) 2 ·12 H 2 O.

  8. Aluminium alloy - Wikipedia

    en.wikipedia.org/wiki/Aluminium_alloy

    Note that the term aircraft aluminium or aerospace aluminium usually refers to 7075. [65] [66] 4047 aluminium is a unique alloy used in both the aerospace and automotive applications as a cladding alloy or filler material. As filler, aluminium alloy 4047 strips can be combined to intricate applications to bond two metals. [67]

  9. Aluminium silicate - Wikipedia

    en.wikipedia.org/wiki/Aluminium_silicate

    Aluminium silicate is a type of fibrous material made of aluminium oxide and silicon dioxide, (such materials are also called aluminosilicate fibres). These are glassy solid solutions rather than chemical compounds. The compositions are often described in terms of % weight of alumina, Al 2 O 3 and silica, SiO 2. Temperature resistance increases ...
