Description

Reg. number CAS: 75-20-7

Chemical formula: CaC2 


With its help combustible gas – acetylene is extracted. Represents chemical compound of calcium with carbon.

By sight solid substance of dark gray or brown color, with a density of 2,4 g/cm3, with a pungent garlick smell. Has ability to absorb water. It turns out by method alloyage of coke with not extinguished lime in special carbide electric arc furnaces at a temperature 2000-2300ºС, on endothermic reaction.

At interaction with water can quickly decays and to emit gaseous acetylene. Forms extinguished lime (withdrawal) in the rest.

At decomposition by water process happens quickly. It is generated big amounts of heat.

Decomposition of carbonaceous calcium happens quicker if clear water. At water decomposition reaction delay happens the polluted extinguished lime.

Application:

It is widely used for carrying out welding works. It is often applied to production of acetylene, cyanamide of calcium and at restoration of alkaline metals.

It is applied in metallurgical and steel industry, to a metal desulfurization. In metallurgy the silikokaltion which serves as additive is used for production. At the same time carbonaceous calcium is applied as a deoxidant which increases mechanical properties of cast iron.
