Product: calcium carbide
Size:15mm-25mm,25mm-50mm,50-80mm,70-100mm,100-120mm.
Package:100kg iron drums, 250kg iron drums.
Physical character:
Industrial products is gray, snuff color or black solid, contain higher of calcium carbide is purple. New
fracture ofcalcium 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 2300centigrade. 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 .
