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.
6-11-2019· Calcining, also called calcination, is an industrial process that uses very high temperatures, often between 1,400-1,800 degrees Fahrenheit (800-1,000 degrees Celsius) or higher, to change the physical and chemical properties of various solid materials, such as minerals, metals, and ore.
