Calcium Carbide 50-80mm

Calcium Carbide 1.Cas no.: 75-20-7 2.80-200mm, 50-80mm. 5-80mm,5-50mm

 Calcium Carbide

Molecular Formula]:	CaC2
[Molecular weight]:	64.10
[Specification]:	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.
[Particle sizes]:	Calcium carbide block: 10-150MM inside Calcium carbide grain: 2-8MM Calcium carbide powder: 200m below The Calcium carbide granularity can be provided accord is to the reguirement of clients.
[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.
[Package, storage and transportation]:	Packed in steel drum of 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.
[Standard]:	Standard:GB10665-2004 Item Premium grade Grade I Grade II Releasecd Volume (L/kg)≥ 300 280 260 PH3 content in Acetylene %(V/V)≤ 0.06 0.08 0.08 PH3 Content in Acetylene %(V/V)≤ 0.10 0.10 0.15
