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 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 to
