Product Description

Calcium Carbide

      Calcium carbide (CaC2) is a pivotal inorganic compound known for its industrial form as gray-black block-like material, often displaying purple or gray cross-sections. When exposed to water, it undergoes an energetic reaction, producing acetylene gas and releasing heat. Primarily, it's employed for two key purposes: as a source of acetylene gas with applications in welding, cutting, and fuel, and as a raw material in organic synthesis for chemicals like vinyl chloride and synthetic resins.

Application

 

Calcium carbide has several specific uses, and here are some primary applications:

1.Acetylene Gas Production: Calcium carbide is a major source of acetylene gas. When calcium carbide reacts with water, it generates acetylene gas. Acetylene gas finds widespread use in welding, cutting, metal processing, as well as in lighting and heating.

2.Organic Synthesis: As a chemical raw material, calcium carbide is employed in the production of various organic compounds. For example, it can be used to synthesize vinyl chloride, chloroprene rubber, synthetic resins, and more.

3.Oxyacetylene Welding: The acetylene gas produced from calcium carbide, when mixed with oxygen, is utilized in oxyacetylene welding, extensively applied in metal welding and cutting.

4.Calcium Cyanamide Production: Calcium carbide can also be used to produce calcium cyanamide, a chemical fertilizer used for plant growth.

5.Desulfurizing Agent: In some industries, calcium carbide acts as a desulfurizing agent, helping to reduce sulfur oxide emissions from combustion.

Please Note:It's important to note that due to the characteristics of calcium carbide, especially its tendency to produce acetylene gas upon contact with water, its applications need to adhere to safety and environmental standards.
