Calcium Carbide

Appearance: Brown, gray, black, purple solid Size:50-80mm Property: Grey, brown or black solid, purple when its purity is higher, the specific gravity is 2.22(18), melting point is 2300, calcium carbide can absorb water in the air and conduct electricity. They higher its purity is, the easier it conducts, it dissolves in water and produce acetylene, calcium hydroxide and releases heat. Items Index Gas yield ≥ 295 L/KG Lump size 50-80mm PH3 ≤ 0.06(V/V) H2S ≤ 0.10 (V/V) Package:50 kg or 100 kg iron drums,or according to the customer demand Usage: (1) the reaction of calcium carbide with water acetylene (CaC2 +2 H-OH → Ca (OH) 2 + CH ≡ CH ↑) many organic compounds can be synthesized, for example: synthetic rubber , synthetic resins, acetone, ketene, carbon black, etc. ; while acetylene-oxygen flame is widely used in metal welding and cutting. (2) heating the powdered calcium carbide with nitrogen, the reaction of calcium cyanamide, namely lime nitrogen, heated lime nitrogen reacts with cyanide salt melt for gold mining and non-ferrous metals industry . (3) can be used in the steel industry itself carbide desulfurization agent. (4) After a fire resulting combustible gas can be lighting.
