Calcium carbide is one of the types of inorganic compounds (chemical formula CaC2) used in modern industry as an intermediate in chemical and other industrial processes. It is a crystalline substance and its color ranges from light brown to black (depending on purity of its components).
Fields of application:
Calcium carbide is used in various industrial fields, including:
iron and steel industry (and construction) – in production of acetylene (obtained by combining CaC2 and water) for gas welding (autogenous) works as well as for purification / recovery of metal from impurities;
chemical industry related to production of synthetic materials that have found application in various fields of human activity, such as synthetic rubber, synthetic resins, vinyl chloride and fertilizers for agriculture used for soil liming ( “dolomitic lime) and control of plant growth.
What is calcium carbide produced from:
In the production of calcium carbide 2 main types of raw materials are used:
Quicklime pure grades of limestone, which is “burned”, and then passed through a special grating that eliminates small and large particles;
carbon compounds in the form of coke (anthracite coal).
