Calcium carbide
Calcium carbide (CAS: 75-20-7), with the chemical formula CaC2, is a solid inorganic compound available as granulated pieces. It is known for its reactivity, particularly its reaction with water to produce acetylene gas. Primarily utilized in industrial applications, it serves as a key reagent in the synthesis of acetylene and in the production of calcium cyanamide, a nitrogen fertilizer. TSS supplies this technical-grade material for various chemical processes.
Acetylene Gas Production
Calcium carbide reacts vigorously with water to generate acetylene (C2H2) gas. This acetylene is a fundamental feedstock for organic synthesis and has historically been used in welding and cutting applications due to its high flame temperature.
Chemical Synthesis
It serves as a precursor for the production of calcium cyanamide (CaCN2), a nitrogen fertilizer and a raw material for various organic compounds. This makes it important in the agricultural and chemical industries.
Desulfurization Agent
In the metallurgical industry, calcium carbide can be used as a desulfurizing agent for iron and steel. It effectively removes sulfur impurities, thereby improving the quality of the metal.
