Provide CALCIUM CARBIDE

Product Name： CALCIUM CARBIDE Detail： H.S.CODE:28491000 Molecular Formula:CaC2 Specification:Grey, brown or black solid, purple when its purity is higher, the specific gravity is 2.22(18 ), melting point is 2300 , 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. Usage: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.
