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.
Structure of trimethylaluminium, a compound that features five-coordinate carbon. A variety of compounds of empirical formula AlR 3 and AlR 1.5 Cl 1.5 exist. [22] The aluminium trialkyls and triaryls are reactive, volatile, and colorless liquids or low-melting solids.

Aluminium sulfate is a salt with the formula Al 2 (SO 4) 3. It is soluble in water and is mainly used as a coagulating agent (promoting particle collision by neutralizing charge) in the purification of drinking water [ 3 ] [ 4 ] and wastewater treatment plants , and also in paper manufacturing.
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 ...
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.
3 (LGP) structure are partially replaced by Al 3+ cations, the LAGP material is obtained with the general formula Li 1+x Al x Ge 2-x (PO 4) 3. [8] The single-phase NASICON structure is stable with x between 0.1 and 0.6; [6] when this limit is exceeded, a solid solution is no more possible and secondary phases tend to be formed. [3]
Aluminides are intermetallic compounds of aluminium. [1] Since aluminium is near the nonmetals on the periodic table, it can bond with metals differently than other metals. The properties of an aluminide are between those of a metal alloy and those of an ionic compound. Aluminides are used as bond coats in thermal barrier coating systems. [2]
