Calcium carbide represents solid crystal matter. The technical product gives crystalline fracture of gray color with different shades depending on purity. At interaction with water even on cold calcium carbide decays with rough release of acetylene and large number of heat. Decomposition of calcium carbide happens also under the influence of atmospheric moisture.
Calcium carbide is applied to receiving acetylene and in production of calcium cyanamide from which receive fertilizers, cyanic connections. Calcium carbide is used when carrying out autogenous works and lighting, and also in production of acetylene black and products of organic synthesis from which the main thing is synthetic rubber. Besides, from calcium carbide receive synthetic rubber, vinyl chloride, acrylonitrile, acetic acid, ethylene, acetylene chlorderivatives, artificial pitches, acetone, styrene. Calcium carbide is used for receiving the carbide and carbamide regulator of growth of plants, production of powder carbide reagent.
