Calcium carbide is a chemical compound with the chemical formula of CaC2. Its main use industrially is in the production of acetylene and calcium cyanamide.
The pure material is colorless, however pieces of technical-grade calcium carbide are grey or brown and consist of only 80-85% of CaC2 (the rest is CaO, Ca3P2, CAS, Ca3N2, SiC, etc. ). Because of presence of pH3, NH3, and H2S, technical-grade calcium carbide has a distinctive smell which some find unpleasant.
Applications
1)Production of acetylene
2)Production of calcium cyanamide
3)Steelmaking
4)Carbide lamps
5)Other uses: In the ripening of fruit, calcium carbide is sometimes used as source of acetylene gas, which is a ripening agent similar to ethylene.
Calcium carbide is used in toy cannons such as the Big-Bang Cannon, as well as in bamboo cannons.
Calcium carbide, together with calcium phosphide, is used in floating, self-igniting naval signal flares, such as those produced by the Holmes' Marine Life Protection Association.
