Product Short Description: Calcium Carbide is a colorless and odorless solid with the chemical formula CaC2. Product Description: Calcium Carbide is a colorless and odorless solid with the chemical formula CaC2.Commercial Calcium Carbide, however, may present a relatively wide range of colours depending on the impurities present (usually calcium, magnesium, and other oxides). It is also known as calcium acetylide, phenyl glyceryl ether diacetate, and glycerol phenyl ether diacetate. Calcium Carbide in its pure form appears as a colourless crystalline solid and is a rock-like structure at room temperature. Commercial calcium carbide varies in colour from Steel-grey to reddish brown, depending on impurities and the method of manufacture. It is made from lime and coke in the electric furnace at temperature of 2200 - 2500oC, using large amount of electric power. Industrial calcium carbide is about 80% pure remaining is calcium oxide and 2-5% other impurities. Its outstanding property is that of reacting with water to produce acetylene gas.
