Calcination is the process of calcium carbonate decomposition into calcium oxide (CaO) and carbon dioxide (CO2), typically occurring at a temperature around 850-900°C. As the calcination is an endothermic reaction (~1.7 MJ/kgCaCO3), fuel is combusted in the calciner. In the rotary kiln, the remaining calcination is completed and clinker is formed.

Like clinker production, clay calcination requires heat. But there is a huge different in scale: in the cement kiln temperatures reach over 1500°C, whereas clay is calcined at 650-850°C. Calcined clay production thus consumes less than half of the specific thermal energy of clinker production.
