Physical and Chemical Properties
The chemistry of calcium carbide is very active. Water heated decomposition to produce acetylene gas and calcium hydroxide, and release a large amount of heat. Action with nitrogen gas to generate calcium cyanogen ammonia.

Application
1.Acetylene generated by the reaction of calcium carbide with water can synthesize many organic compounds, such as synthetic rubber and artificial rubber

Resin, acetone, ketene, carbon black, etc; At the same time, acetylene oxygen flame is widely used for metal welding and cutting.

2. When heating powdered calcium carbide with nitrogen, the reaction generates calcium cyanamide, namely lime nitrogen. The cyanide melt generated by the reaction of heated lime nitrogen with table salt is used for gold mining and non-ferrous metal industry.

3. Calcium carbide itself can be used as a desulfurizer in the steel industry.

4. Calcium carbide is one of the basic raw materials in the organic synthesis chemical industry. It is an important raw material for acetylene chemical industry. Acetylene made from calcium carbide is widely used in metal welding and cutting

Storage
Store in dry, cool, and ventilated places. It must be kept away from fire sources, open fires, and sunlight. Use of specialized calcium carbide containers.
