  • Calcium carbide Wikipedia

    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. The pure material is colorless, however pieces of technical-grade calcium carbide are grey or brown and consist of about 80–85% of CaC2 (the rest is CaO (calcium oxide), Ca3P2 (calcium phosphide), CaS (calcium sulfide), Ca3N2 (calcium nitride), SiC (silicon carbide), etc.). In the presence of trace moisture

  • Calcium Carbide an overview ScienceDirect Topics

    For every ton of calcium carbide, about 250 to 330 m 3 of gas is released (72% vol. CO, 5 CO 2, 7 to 8 H 2, <0.1 CH 4, balance N 2). Dust content in the gas is 100 to 150 mg/m 3 and it is removed by scrubbers (cleaning of 1000 m 3 of gas consumes 2.7 to 3.5 m 3 water). The calcium carbide melt is tapped through a tap hole into the water-cooled drums.

    01.07.2020· Calcium carbide is produced industrially in an electric arc furnace, from a mixture of calcium oxide and coke (or pure carbon) at approximately 2000 °C. CaO + 3 C → CaC 2 + CO. Another method involves the reaction between finely divided calcium metal and powdered carbon (activated charcoal e.g.), at 810°C in an inert atmosphere. This reaction is highly exothermic, the calcium will

    Silicon carbide (SiC) is a compound of silicon metalloid and oxygen. Typically, SiC is used in the alpha silicon carbide structural form. Silicon carbide is a black, high-hardness ceramic that is usually harder than alumina. Depending on the addition of impurities SiC may be green or black in color.

  • Commercialization of Calcium Carbide and Acetylene

    The first commercial calcium carbide plant, built by local entrepreneur James Turner Morehead (1840-1908), operated here between 1894 and 1896. From this beginning, calcium carbide and acetylene manufacturing spread around the world. Acetylene, used first for lighting homes, railways, mines, and marine buoys and then for oxyacetylene welding, became one of the foundations of the synthetic
