Kaolin or china clay is a mixture of different minerals. Its main component is kaolinite; in addition, it frequently contains quartz, mica, feldspar, illite, and montmorillonite. Kaolinite is made up of tiny sheets of triclinic crystals with pseudohexagonal morphology. It is formed by rock weathering.
Kaolin is a rock from which the clay mineral kaolinite is derived. This one has been used for millennia as the principal ingredient in porcelain tableware. Today Imerys kaolins bring critical properties to a host of end applications ranging from paper to paints, fiberglass to cosmetics and pharmaceuticals.
