Kaolin is an aluminosilicate soft white mineral named after the hill in China (Kao-ling) from which it was mined for centuries. In its natural state kaolin is a white, soft powder consisting principally of the mineral kaolinite, and varying amounts of other minerals such as muscovite, quartz, feldspar, and anatase.

Novel nanosized kaolin clay particles are prepared by agitating a fine particle size fraction of kaolin clay in a Netzsch mill until the particle size is reduced, aspect ratio is decreased and surface area is increased. The ultrafine kaolin particles are especially useful as a pigment to provide high surface gloss to ink jet printing papers.
