Calcium carbide

 

Calcium carbide (carbonaceous calcium, calcium acetylenide) - CaC2 is a pure white crystalline substance. Compound of calcium with carbon.

Calcium carbide is produced by fusing carbonite and quicklime in electric furnaces. Molten calcium carbide releases from the furnace into special molds, where it hard. Harden calcium carbide crushes and sorts into of a certain size pieces.

Technical calcium carbide is a hard-crystalline substance. Calcium carbide is a dark gray or brown solid in appearance. Depending on the purity it gives a gray crystalline fracture with different shades. Calcium carbide greedily absorbs water., calcium carbide decomposes with a violent release of acetylene and a large amount of heat interacting with water, even cold. Decomposition of calcium carbide also occurs under the influence of atmospheric moisture.
