  2. Aluminium sulfide - Wikipedia

    en.wikipedia.org/wiki/Aluminium_sulfide

    Aluminium sulfide is a chemical compound with the formula Al 2 S 3. This colorless species has an interesting structural chemistry, existing in several forms. The material is sensitive to moisture, hydrolyzing to hydrated aluminium oxides/hydroxides. [1] This can begin when the sulfide is exposed to the atmosphere.

  5. Sulfide - Wikipedia

    en.wikipedia.org/wiki/Sulfide

    Sulfide (also sulphide in British English) [2] is an inorganic anion of sulfur with the chemical formula S 2− or a compound containing one or more S 2− ions. Solutions of sulfide salts are corrosive. Sulfide also refers to large families of inorganic and organic compounds, e.g. lead sulfide and dimethyl sulfide.

  6. Ammonium alum - Wikipedia

    en.wikipedia.org/wiki/Ammonium_alum

    Ammonium aluminium sulfate, also known as ammonium alum or just alum (though there are many different substances also called "alum"), is a white crystalline double sulfate usually encountered as the dodecahydrate, formula (NH 4)Al(SO 4) 2 ·12H 2 O. It is used in small amounts in a variety of niche applications.

    As aluminium is a small atom relative to these chalcogens, these have four-coordinate tetrahedral aluminium with various polymorphs having structures related to wurtzite, with two-thirds of the possible metal sites occupied either in an orderly (α) or random (β) fashion; the sulfide also has a γ form related to γ-alumina, and an unusual ...

    en.wikipedia.org/wiki/Sulfosalt_mineral

    Sulfosalt minerals are sulfide minerals with the general formula A m B n X p, where A represents a metal such as copper, lead, silver, iron, and rarely mercury, zinc, vanadium; B usually represents semi-metal such as arsenic, antimony, bismuth, and rarely germanium, or metals like tin and rarely vanadium; X is sulfur or rarely selenium and/or ...
