Production of acetylene gas: Calcium carbide produces acetylene gas through a chemical reaction with water. Acetylene gas is used as a fuel for welding and cutting torches and as a raw material for making various chemicals.

Production of synthetic rubber: Calcium carbide is used as a raw material in the production of synthetic rubber, which is used in the manufacturing of tires, belts, hoses, and other industrial products.

Production of polyvinyl chloride (PVC): Calcium carbide is used as a raw material in the production of PVC, a common plastic used in a variety of products, including pipes, wire insulation, and vinyl flooring.

Production of acetylene-based chemicals: Acetylene gas produced from calcium carbide is used as a raw material in making chemicals such as vinyl chloride, acrylonitrile, and other specialty chemicals.

Desulfurization of iron and steel: Calcium carbide is used in desulfurizing iron and steel, helping to remove impurities and improve the quality of the final product.

Welding and cutting: Acetylene gas produced from calcium carbide is used as a fuel gas in welding and cutting torches, making high-temperature flames for metalworking applications.

Lighting: Acetylene gas produced from calcium carbide can be used in gas lamps and lanterns for lighting and heating applications, particularly in areas without electricity.
