1. Introduction. Kaolin is a white-brown powdery clay mineral. It has the main constituent of kaolinite of a hydrous aluminum silicate (Al 2 O 3.2SiO 2.2H 2 O) with a single tetrahedral silicate layer linked via oxygen molecules to a single alumina octahedral layer. The most common auxiliary minerals found with kaolin are maternal rocks such as …
It also contains small amounts of quartz and organic matter. On the other hand, Kaolin clay has a higher concentration of kaolinite, a pure form of clay mineral, giving it its unique properties. Kaolin clay is less plastic and more refractory, making it suitable for ceramic applications that require high heat resistance.
