The Calcination of Kaolin Clay - FEECO International Inc.

While kaolin clay is widely used in its “raw” form, heat treating kaolin to produce metakaolin and other forms of calcined kaolin further increases its usability and creates an engineered product. Calcination can enhance or alter a variety of the mineral’s properties to produce a material with characteristics suited to a given application.

Calcination - Wikipedia

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.
