Item: Calcium carbide1. Molecular formula: CaC2 2. Molecule weight: 64.10 3. CAS No.: 75-20-7 4. HS code: 28491000 5. Gad yield: 280-290L/kg, 295L/kg, 305L/kg 6. Properties Fresh calcium carbide is of a violet-red colour that appears blue-violet on the fracture, is a strong hygroscopic substance, is decomposed readily by atmospheric humidity and has a characteristic garlic-like odour. On contact with water or in damp surroundings, easily flammable gaseous acetylene is formed and explosive atmospheres can be produced. 7.
