Calcium Carbide 

CAS No.: ******7 
EINECS No.: ********3 
MF: CaC2 
MW: *4.*0 
HS code: *******0 

Appearance: 
Brown or black solid block, its pure materials is colorless crystals. 

Property: 

1. Size: **4mm, **7mm, ***5, ****5, ****0mm, ****0mm, *****0mm 
2. Gas yield: **5L/KG***5L/KG 

Application: 

1. Production of acetylene 

Reaction principle: CaC2 *2 H2O == Ca (OH) 2 + C2H2 
CaC2 can be conductive, the higher the purity, electrical conductivity more easily. 

2. Other Uses 

(1) calcium carbide reacts with water to many organic compounds can be synthesized acetylene 

For example: Synthetic rubber, artificial resins, acetone, ketene, carbon black, etc.; While an oxygen acetylene flame is widely used in metal welding and cutting. 

(2) heating powdered calcium carbide and nitrogen, the reaction of calcium cyanamide, that lime nitrogen, heating lime nitrogen and salt used to melt the reaction of cyanide gold mining and non-ferrous metals industry. 

(3) calcium carbide can be used for the steel industry itself, the desulfurization agent.
