What is Calcium Carbide Made Of?

Calcium carbide is primarily made from limestone (calcium carbonate) and carbon (in the form of coke or anthracite) through a high-temperature reaction in an electric arc furnace. The resulting product contains calcium and carbide ions, making it a key player in chemical manufacturing.

Production Process

• Raw Materials: Limestone and carbon.
• Temperature: The process requires a temperature of around 2000°C.
• Reaction: CaCO₃ + 3C → CaC₂ + 3CO.

This reaction efficiently produces calcium carbide in large quantities, crucial for various industrial applications.

Applications of Calcium Carbide

Calcium carbide is predominantly used to produce acetylene gas, a critical component in welding and metal cutting. It is also utilized in the manufacture of plastics, chemicals, and as a desiccating agent for moisture removal in certain industrial processes.

Statistical Insights

According to the Global Calcium Carbide Market Report 2021, the demand for calcium carbide is expected to grow by 4.5% annually through 2026, highlighting its importance in various industries around the world.

Case Study: Use in Acetylene Production
