Kaolin clay, also known as China clay, is an essential industrial mineral primarily made up of the mineral kaolinite – a hydrous aluminum silicate. Kaolin can be found in applications all around us, from consumer products, to advanced industrial processing.
Kaolin, commonly referred to as china clay, is a clay that contains 10-95% of the mineral kaolinite and usually consists mainly of kaolinite (85-95%). In addition to kaolinite, kaolin usually contains quartz and mica and also, less frequently, feldspar, illite, montmorillonite, ilmenite, anastase, haematite, bauxite, zircon, rutile, kyanite, silliminate, graphite, attapulgite, and halloysite.
The main process important for production high reactivity pozzolana from kaolin clay is calcination. The heating process drives off water from the mineral kaolinite (Al 2 O 3·2SiO 2 ·2H 2 O), the main constituent of kaolin clay, and collapses the material structure, resulting in an amorphous aluminosilicate (Al 2 O 3·2SiO 2), metakaolinite.
