CalcinationWikipedia

CalcinationWikipedia

In limestone calcination a decomposition process the chemical reaction is CaCO 3 → CaO CO 2 (g). The standard Gibbs free energy of reaction is approximated as ΔG° r = 177 100 − 158 T (J/mol). The standard free energy of reaction is 0 in this case when the temperature T is equal to 1121 K or 848 °C. Oxidation. In some cases calcination of a metal results in oxidation of the metal.
