Grey, brown or black solid, purple when its purity is higher, the specific gravity is 2.22(18°C), melting
point is 2300°C, the product can absorb water in the air and conduct electricity. They higher its purity
is, the easier it conducts, it dissolves in water, turns into acetylene and calcium hydroxide and releases heat.
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.
Packed in steel drum of 50 or 100kg, net each and marked with "calcium carbide avoid fire and water" on the side,
Stored in cool, venilated and dry warehouse and kept away from water and moisture.
