Calcium carbide
Calcium Carbide, commonly known as "calcium carbide", is an inorganic compound. At room temperature, it is a grayish-black block or granular solid. Industrially, it is produced by calcining quicklime (CaO) in a high-temperature electric arc furnace and reacting it with coke (C). It is an important chemical raw material and is mainly used in the production of acetylene
