Calcium Carbide

Calcium carbide is a chemical compound mainly use industrially in the production of acetylene and calcium cyanamide.

When pure, it is colorless, however, pieces of technical-grade calcium carbide are grey or brown. In the presence of trace moisture, technical-grade calcium carbide emits an unpleasant odor reminiscent of garlic.

Applications of calcium carbide include manufacture of chemicals for fertilizer, and in steelmaking, it is used in the desulfurization of iron (pig iron, cast iron and steel). As a fuel, it is use to extend the scrap ratio to liquid iron, depending on economics, and as a powerful deoxidizer for ladle treatment

In the artificial ripening of fruit, calcium carbide is sometimes used as source of acetylene gas, which is a ripening agent similar to ethylene.
