Nature：
Industrial products are gray, yellow-brown or black solids, and purple with higher calcium carbide content. The new fracture surface of calcium carbide is shiny, and it is grayish white when exposed to air due to moisture absorption. Relative density2. 22。 Industrial products generally contain 80% calcium carbide. Melting point 2300 °c. Can conduct electricity, the higher the purity, the easier it is to conduct electricity. The chemical properties are very active and can react with many gases and solutions at the right temperature. When exposed to intense decomposition of water, acetylene gas and calcium hydroxide are produced, and a large amount of heat is released. It can undergo intense chemical reactions with chlorine, hydrogen chloride, sulfur, phosphorus, ethanol, etc. at high temperatures.
Use：
Acetylene gas can occur by the interaction between calcium carbide and water, which is an important basic raw material for organic synthesis. Acetylene gas can be used to prepare polyvinyl chloride, neoprene, calcium cyanamide, acetic acid, vinyl acetate ethanol and its derivatives, cyanidation，Complexes, dicyandiamide and acetone, etc. calcium carbide reacts with nitrogen to produce lime nitrogen, which can be used as agricultural fertilizer. Acetylene is used for metal cutting and welding with calcium carbide.
Application:
1).The main raw material for producing acetylene gas
2).Cutting and welding for metal material.
3).To synthesize polyvinyl chloride(PVC).
4).Fruit catalyst.
5).The basic material for organic synthesis and calcium cyanamide
