China's sizable share of the global calcium carbide market is linked to the country's strong economic growth, large coal reserves, and ever-increasing acetylene demand for chemicals. Calcium carbide to PVC, considered an antiquated process in developed parts of the world, represents over 80% of China's total PVC production.
Calcium carbide is made by heating calcium carbonate and subsequently reducing CaO with carbon (e.g. petrol coke), according to the follow reaction: (1) CaCO 3 → CaO + CO 2 (2) CaO + 3C → CaC 2 + CO (CO + O 2 → CO 2) The process for manufacturing calcium carbide is illustrated in Fig. 3.Limestone is converted to lime in a limekiln, while moisture is removed from coke in a coke dryer.
Silicon carbide (SiC) is a compound of silicon and carbon with a chemical formula of SiC. The simplest manufacturing process for producing silicon carbide is to combine silica sand and carbon in an Acheson graphite electric resistance furnace at a high temperature, between 1600°C (2910°F) and 2500°C (4530°F).

May 22, 2018· After cooling, the calcium carbide was crushed to various sizes and packaged in metal cans (also manufactured at the Ivanhoe plant). The manufacturing process can be represented by the chemical equation: CaO + 3 C = CaC2 + CO. Calcium carbide was important in coal mining because of the light produced by the flame of a carbide lamp.
Calcium carbide, also known as calcium acetylide, is a chemical compound with the chemical formula of Ca C 2.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 CaC 2 (the rest is CaO (calcium oxide), Ca 3 P 2 (calcium phosphide ...
Willson made the first sale of calcium carbide, 1 ton, to Eimer and Amend, a New York chemical and apparatus supply house, on January 29, 1894. Fortune smiled again when, in August 1894, they sold their patents for the use of carbide and acetylene in lighting to a new firm, the Electrogas Company, but retained the rights for chemical manufacturing.
On May 2, 1892, in Spray (now Eden), Canadian chemist Thomas L. Willson accidentally produced calcium carbide and acetylene with an electric-arc furnace. In August, Willson applied for a patent for the new process. By 1897, acetylene was competing with electricity in providing lighting, especially in rural areas and those places where gasoline was unavailable.
