Pure limestone and marble are composed of calcium carbonate: CaCO 3. In air, the temperature required for calcium carbonate decomposition is 898 °C (considering simple equilibrium and ignoring any vapour pressure effects). As pressure increases, the temperature requirement for this equilibrium decomposition increases very rapidly.
Does anybody know how to reduce decomposition temperature of Calcium Carbonate? ... For example, in limestone calcination, a decomposition process, the chemical reaction is.
Decomposition behavior of limestone in early converter slag was studied at 1300–1400 °C. The decomposition process is a mixed control of chemical reaction and heat conduction through lime layer. Effective thermal conductivity and chemical reaction rate constant are obtained.
The decomposition of limestone produces quicklime( CaO) and carbon dioxide, given by the following equation: CaCO 3 (s)----> CaO (s) + CO 2 (g). How many kilograms of calcium carbonate must be decomposed to form 750g of quicklime?

Thermal decomposition, or thermolysis, is a chemical decomposition caused by heat. The decomposition temperature of a substance is the temperature at which the substance chemically decomposes. The reaction is usually endothermic as heat is required to break chemical bonds in the compound undergoing decomposition.
