In carbide: Ionic carbides .important of these compounds is calcium carbide, CaC 2. The primary use for calcium carbide is as a source of acetylene for use in the chemical industry. Calcium carbide is synthesized industrially from calcium oxide (lime), CaO, and carbon in the form of coke at about 2,200 °C (4,000 °F). Pure.

Calcium Carbide Calcium carbide is a chemical compound with the chemical formula of CaC2. Its main use industrially is in the production of acetylene and calcium pure material is colorless, however pieces of technicalgrade calcium carbide are .

Limestone Calcium Carbide Acetylene . Limestone. Limestone often contains variable amounts of silica in the form of chert or flint, as well as varying amounts of clay, silt and sand as disseminations, nodules, or layers within the rock.
