Calcined kaolin is not commonly used in traditional ceramics, except for the specifics mentioned below, but it is a commodity material in many industries. Various grades of calcined kaolin are produced by varying parameters in the calcination process (e.g. retention time in the rotary kiln, firing temperature). Calcination initially converts it ...
Based on chemical composition kaolin is broadly classified as either hydrous kaolin or calcined kaolin. When water molecule is attached to the kaolin, it is referred to be hydrous. This water molecule is removed from the hydrous clay through a process known as calcination, which involves heating the clay to high temperatures.

Calcined kaolin is a high-temperature calcination process for kaolin, usually carried out in the temperature range of 800°C to 1,200°C. This process can change the structure of kaolin, causing it to lose adsorbed water and other volatile substances.
Slightly less calcined clay than raw clay is used because the calcining process drives off water and makes the calcined clay lighter for the same amount of alumina and silica it contains. In other words, calcined clay contains more alumina and silica per gram than uncalcined clay does.
