Description Calcium Carbide
:
Calcium carbide is a grayshi-black crystalline compound obtained by
heating pulverized limestone or quicklime with carbon and used to
generate acetylene gas, as a dehydrating agent,and in the
manufacture of graphite and hydrogen.Calcium carbide is also used
as a fule in steelmaking to extend to scrap ratio to liquid iron
depending on economics. It is also used as a powerful deoxidizer at
ladle treatment facilities.

Uses Of Calcium Carbide :
Calcium carbide is a very important basic material in the organic synthesis industry.When mixed with other materials; the combination can produce acetylene, chloroprene rubber, calcium cyanamide, acetate acid, trichloroethylene, and acetaldehyde. Moreover, it can be used as a desulfuring agent in steel manufacturing and is used for metal cutting and welding .
Property: Grey, brown or black solid, purple when its purity is higher, the specific gravity is 2.*2(*8), melting point is ***0; 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 release hea .
Storage/Transport
Calcium carbide drum should be sealed. Stored in dry, cool and draughty place.Store away from oxidizing substances.Oxygen is required to maintain stability of inhibited monomers.Avoid contact with incompatibles such as oxidizing agents,strong bases,acids and moisture in air.Aoid contact with heat,spark or flame.
Rolling drums, heavy putting down and colliding are not allowed to avoid the spark lead to explosion.
GreatLion Group have a excellent record about package,storage,transport in chemical products.
We hope to build long-term business with you in competitive price and high quality.
