Characteristic
Calcium carbide, also known as calcium acetylide, is a chemical compound with the chemical formula of CaC2. Its main use industrially is in the production of acetylene and calcium cyanamide.
Chemical formula：CaC2
Molar mass：64.099 g/mol
Appearance：White powder to grey/black crystals
Density：2.22 g/cm3
Melting point：2,160 °C (3,920 °F; 2,430 K)
Boiling point：2,300 °C (4,170 °F; 2,570 K)
Solubility in water：Rapid hydrolysis
Crystal structure：Tetragonal
Application
Calcium carbide is used as a desulfurizer, dehydrant of steel, fuel in steel making, powerful deoxidizer and as a source of acetylene gas. It is used as a starting material for the preparation of calcium cyanamide, ethylene, chloroprene rubber, acetic acid, dicyandiamide and cyanide acetate. It is used in carbide lamps, toy cannons such as the big-bang cannon and bamboo cannon. It is associated with calcium phosphide and used in floating, self-igniting naval signal flares. Further, it is involved in the reduction of copper sulfide to metallic copper.
