Calcination - Wikipedia. In limestone calcination, a decomposition process that occurs at 900 to 1050ºC, the chemical reaction is CaCO 3 (s) → CaO (s) + CO 2 (g). Today, this reaction largely occurs in a cement kiln.. The standard Gibbs free energy of reaction is approximated as ΔG° r ≈ 177,100 − 158 T (J/mol).
