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.*2 (*8 centigrade)
Industrial product calcium carbide content *0%. Melting point ***0
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.
Use: Calcium carbide is an important basic material in organic
synthesis industry, Acetylene obtanied from calcium carbide is
raw material to make ethylene, chloroprene rubber, calcium
cyanamide, acetic acd, acetaldehydr, ethylacetate, cyanide acetate,
dicyandiamide, acetone, octanol, trichloride ethylene etc.Also
used as desulfurizer and dehydrant of steel and for cutting and
welding metals.
