Aluminium Sulfide :: Aluminium Sulphide


Aluminium Sulfide or aluminium sulphide is a chemical compound with the formula Al2S3. It comprises yellowish-gray lumps and has the odour of hydrogen sulphide. The material is sensitive to moisture, hydrolyzing to hydrated aluminium oxides/hydroxides. This can begin when the sulfide is exposed to the atmosphere. The hydrolysis reaction generates gaseous hydrogen sulfide (H2S).


Aluminium sulphide is used to prepare hydrogen sulphide for purification of hydrochloric acid and sulphuric acid, precipitating sulphides of metals, analytical reagent, source of sulphur and hydrogen.
