Calcium carbide (calcium carbonate, calcium acetylenide) GOST 1460-81 drum 100, whosale has a solid crystalline structure. In its pure form, the substance consists of white crystals. Pieces of technical carbonaceous calcium can have a dark gray, brown or black color. The shade acquired by the substance is due to the fact that the production of calcium carbide is carried out in electric furnaces by fusing quicklime and coal at a high temperature, reaching 1900-1950°C.
The chemical formula is CaC2.
