Clinker Production an overview | ScienceDirect Topics
Calcination is the main process of clinker production, calcining calcium carbonate (CaCO 3) at about 900 °C to form calcium oxide, CaO, lime, and the release of carbon dioxide gas (CO 2).In the next step of the socalled clinker treatment, calcium oxide (CaO) is exposed to temperatures of 1400 °C to 1500 °C together with silica (SiO 2), aluminum oxide (Al 2 O 3), and ferrous oxide (Fe 2 O 3).
