Aluminium Sulfide Formula

Aluminium sulfide or aluminium sulphide is a grey chemical compound with a chemical formula Al2S3. It readily hydrolyses in the air to form hydrogen sulfide. Aluminium sulfide is a greyish solid that posses a strong sulfide smell. It has six crystalline forms: α, β, γ and δ. It can be prepared through a thermite-like reaction between sulfur and aluminium powders. In this article, learn the aluminium sulfide formula and its chemical structure along with its properties and uses.
