Kaolin - Production and Consumption in Asia - AZoM

Kaolin Kaolin is fine white clay mainly composed of kaolinite but other related minerals such as halloysite are also considered. Kaolin is formed through the alteration or kaolinization of feldspar-rich parent rocks by weathering or hydrothermal processes. The ultimate breakdown product of most rock-forming minerals is kaolinite.
