Kaolin is a type of rock that contains clay mineral groups and is an industrial mineral commodity; the groups generally include kaolinite, halloysite, dickite, and nacrite. 3 Amongst these four clay types, the most important is kaolinite because it is well-known for its good properties, including notably high whiteness or near whiteness ...
The group includes the dioctahedral minerals kaolinite, halloysite, dickite, and nacrite, and the trioctahedral minerals chrysotile, antigorite, chamosite, and cronstedite. Halloysite and disordered forms of kaolinite seem to be the only members of the group formed in soils. The other minerals are formed hydrothermally or by regional metamorphism.
