Product Description
                                                             Grey purple solid stone calcium carbide
Chemical formula: CaC2 
Calcium carbide is lumpy substance, its surface is a little deep gray, has slight nasty smell
This product is lumpy substance, its surface is a little deep gray, has slight nasty smell. It can produce acetylene gas when met water, it can burn when meets fire. The acetylene gas mix with air will form explosive gas (explosive range of acetylene gas in the air is 2.3% - 81%).

11. Packing

50kg or 100kg iron drum

Cautions during transportion:
The packing must be kept in good condition and the goods should be stored in a dry,
cool and ventilated place.
It should be separate from the cargo can burn and acid.
It should avoid meeting water and moisture.
It should give off the acetylene in iron drum before storing in warehouse.
Rolling drums,heavy putting down and colliding are not allowed to avoid the spark leads to explosion.
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 releases heat.
Use: 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.
Packing: 50kgs/100kgs new iron drums.
