Calcium Carbide is a crystalline powder or a grayish black lump with a garlic-like odor. It is commonly used to generate acetylene gas, and also used as a reducing agent and in steel manufacturing and metal cutting. Calcium Carbide is extremely hazardous as it contains traces of arsenic and phosphorus that is dissolved in water, the carbide produces acetylene gas. It induces prolonged hypoxia that may affect the neurological system. Calcium Carbide is the primary use for calcium carbide as source of acetylene for use in the chemical industry. It is synthesized industrially from calcium oxide, CaO, and carbon.
