calcium carbide CaC2

Calcium carbide, an inorganic compound with the chemical formula CaC2, is the main component of calcium carbide, which is a white crystalline powder, and the industrial product is a grayish-black lump with a purple or gray cross-section. It reacts violently with water immediately, generating acetylene and releasing heat. Calcium carbide is an important basic chemical raw material, mainly used to generate acetylene gas. It is also used in organic synthesis and oxyacetylene welding.
