1. Physical character:

Industrial products is gray, snuff color or black solid, contain higher of calcium carbide is purple. New fracture of calcium carbide has luster, reveal in the air to lose lustre show offwhite because of the calcium carbide imbibe moisture. Relative density 2.22 (18 centigrade). Industrial product calcium carbide content 80%. Melting point 2300 centigrade. Can conduct electricity, the higher purity, the higher conduct electricity. Chemical property is very lively, at the appropriate temperature can reaction with a lot of gas, solution. Touch with water drastic decompound and bring acetylene and calcium hydroxide, disengaging large numbers of heat. Has drastic chemical reaction with chlorine, hydrogen chloride, sulfur, phosphorus, alcohol etc. At high temperature.
