Use
Calcium carbide is the most relevant carbide industrially because of its important role as the basis of acetylene industry. In some locations, acetylene is also used to produce vinyl chloride, the raw material for the production of PVC. A less important use of Calcium Carbide is related to the ferilizers industry. It reacts with nitrogen to form calcium cyanamide, which is the starting material for the production of cyanamide (CH2N2). Cyanamide is a common agricultural product used to stimulate early foliation. Calcium Carbide can also be employed as desulfurizing agent for producing low-sulfur carbon steel. Also, it is used as a reducing agent to produce metals from their salts, e.g., for direct reduction of copper sulfide to metallic copper.
