Kaolinite clay mineral
WebbIn its fully hydrated form the formula is Al 2 Si 2 O 5 (OH) 4 -2H 2 O. Kaolinite is a very important industrial mineral, and halloysite is becoming increasingly important due mainly to its use in nanotechnology applications which take advantage of its tubular habit. Analyses: Kaolins and halloysites can be analysed by a variety of methods. WebbKaolinization of 2:1 type clay minerals commonly occurs in the supergene environments of the Earth, which plays critical roles in many geochemical and environmental processes. However, the transformation mechanism involved and the specific behavior of 2:1 type swelling and non-swelling clay minerals during kaolinization remain poorly understood.
