calcium carbide CAS 75-20-7
Overview
Calcium Carbide (Chemical Formula: CaC2), typically known as “Calcium Acetylide,” is a vital industrial chemical produced by the reaction of lime and coke in an electric arc furnace at temperatures reaching 2200°C. At Shandong Yinglang Chemical, we supply premium export-grade Calcium Carbide characterized by its high gas yield, low impurity content, and stable reaction rates. When brought into contact with water, it vigorously generates Acetylene (C2H2)
