The aluminium sulfide formula, also known as aluminium sulfide, is a chemical compound composed of aluminium and sulfur. Its formula and various aspects related to it are essential for understanding its properties and behaviour.
Aluminium Sulfide Formula
The aluminium sulfide formula is Al₂S₃. It consists of two aluminium (Al) atoms and three sulfur (S) atoms, which combine in a specific ratio to form this compound.
Among its many forms, aluminium sulfide has six crystalline forms. Aluminium sulfide is synthesized by thermitic reactions between aluminium powders and sulfur.
In addition to being known as dialuminium trisulfide, aluminium sulfide is an inorganic compound that is often used as a raw material during the synthesis of hydrogen sulfide. Additionally, it is moderately water-soluble and acid-soluble. Also, aluminium sulfide has a fascinating structural history and exists in several forms. It is also sensitive to water, hydrolyzing to hydrated aluminium oxides.
The term “aluminium sulphide” is a common alternative spelling for aluminium sulfide. It refers to the same compound, and its chemical formula remains Al₂S₃.
