Calcination is one of the most common processes used in the ceramics industry among many others. The most common application for Calcining is the decomposition of calcium carbonate to calcium oxide and carbon dioxide, in order to create cement.
The calcination process normally takes place at temperatures below the melting point of the product materials. One of the most common applications is as a step in the production of Portland cement, in which calcium carbonate (limestone) is calcined at around 850°C to produce calcium oxide (quicklime) and carbon dioxide.
