Caclium Carbide 50-80mm

Formula: CaC2 Molecular weight: 64.10 CAS No.: 75-20-7 UN No.: 1402 Hazard Class: 4.3 H. S. Code: 28491000 Quality standard: Gb10665-1997 Description: 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.
