(1) calcium carbide reaction with water generated acetylene can be synthesized many organic compounds, such as synthetic rubber, man-made
Resin, acetone, ketene, such as carbon black, Meanwhile acetylene a widely used in metal oxygen flame welding and cutting.

(2) the powdery calcium carbide heating with nitrogen, reaction products.it cyanogen ammoniation, namely lime nitrogen, calcium lime n and salt reaction heat generated cyanogen melt used for mining gold and non-ferrous metal industry.
