Kaolin | Al2H4O9Si2 - PubChem

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.
