Product Name: Calcium Carbide
Gas release: >=295L/kg
Size(mm): 80-120mm
Packing: 100kg/bucket diameter: 560*670
Pail pack colour: Black gray green
Uses: Calcium carbide is an important basic material in organic synthesis industry, Acetylene obtained from calcium carbide is raw material to make ethylene,
chloroprene rubber, calcium cyanamide, aceticacid, acetaldehydr, ethylacetate, cyanideacetate, dicyandiamide, acetone, octanol, trichloride ethylene tec.
Also used as desulfurizer and dehydrant of steel and for cutting and welding metals.
Property: 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 release heat.

1. It is called calcium carbide( CaC2). It is a hard lump and the cross section is dark grey or brown.
2. It is lumpy substance, its surface is a little deep gray, has slight nasty smell.
3. It can produce acetylene gas when met water, it can burn when meets fire.
4.The acetylene gas mix with air will form explosive gas (explosive range of acetylene gas in the air is 2.3% - 81%)
Packing details: 50kg drum packing,100kg drum packing.
Shipment: about 15days
