Applications of Calcium Carbide (CaC₂)

                                        Applications of Calcium Carbide (CaC₂)

Calcium carbide, a chemical compound with the formula CaC₂, is widely used in various industrial and chemical processes due to its ability to produce acetylene gas (C₂H₂) upon reaction with water. Key application areas include:

1. Acetylene Production

Calcium carbide reacts with water to form acetylene gas, a crucial fuel for oxy-acetylene welding and cutting in metalworking.

Acetylene is also used in chemical synthesis (e.g., producing plastics, solvents like vinyl chloride, and synthetic rubber).

2. Chemical Industry

Raw material for manufacturing calcium cyanamide (a fertilizer and nitrogen fixation agent).

Used in producing vinyl chloride monomer (VCM), a precursor for polyvinyl chloride (PVC).

Key intermediate in organic synthesis (e.g., for synthetic resins and acetic acid).

3. Steelmaking & Metallurgy

Acts as a desulfurizing agent to remove sulfur from iron and steel.

Sometimes used as a fuel source in metallurgical processes.
