Calcium carbonate decomposition | CaCO 3 = CaO + CO 2 Calcium carbonate is heated into higher temperature and take calcium oxide (CaO). CaCO 3 decomposes into CaO and CO 2 above 825 0 C.CALCIUM CARBIDE STORAGE AND HANDLINGCalcium carbide is produced by a reaction between coke and burnt lime in an electric furnace at a temperature of 2000°C. Molten carbide is tapped from the furnace and run into moulds where it is left to solidify. When it cools it is crushed and screened by size. The manufacturing process requires large amounts of electricity. Crushing and screening Burnt Lime (CaO) 880 kg Coke ( C ) 560 kg ...
