Calcium Carbide - an overview ScienceDirect Topics

Calcium carbide has the nominal formula of CaC2 and the molecular weight of 64.0992 g/mol. The pure material is colorless, but most samples have a color ranging from black to grayish-white, depending on the grade. Its density is 2.22 g/cc and it melts at 2160 °C with a boiling point (under an inert atmosphere) of 2300 °C, where it decomposes.

11.4 Calcium Carbide Manufacturing - EPA

Calcium carbide (CaC2) is manufactured by heating a lime and carbon mixture to 2000 to 2100°C (3632 to 3812°F) in an electric arc furnace. At those temperatures, the lime is reduced by carbon to calcium carbide and carbon monoxide (CO), according to the following reaction: CaO+3C→CaC2 +CO Lime for the reaction is usually made by calcining limestone in a kiln at the plant site. The sources ...

Effect of Calcium Carbide on Concentration of Trace ...

Abstract: The study examined the effects of calcium carbide as a fruit ripening agent on the concentration of trace element in Mango, pawpaw and banana. Calcium carbide was administered to 12 samples (mango, banana and pawpaw) at three different concentrations (1 g/kg, 5 g/kg and 10 g/kg of calcium carbide per kilogram of fruit) and control (0 g/kg). The samples were analysed for calcium ...
