1 Introduction. Kaolinite is described as a 1:1 clay mineral consisting of two layers joined through an apical oxygen. One layer is known as the siloxane layer and consists of silicon tetrahedra joined in an hexagonal array. This layer is coupled to a gibbsite-like layer consisting of octahedral aluminium bonded to four OH units and two …

A kaolinite particle is made of 70-140 layers of individual structural units. The chemical formula of kaolinite is Al 2 Si 2 O 5 (OH) 4 and its molecular weight is 258.16 g. It is white, brownish white, grayish white, yellowish white, or grayish green in color. The specific gravity of the mineral is about 2.6.

The CEC of kaolinite strongly depends on the particle size (both thickness and diameter in the (00l plane) and pH value. Particle size is more important than crystallinity in affecting kaolinite CEC. ... Ma, C. (1996) The ultra-structure of kaolin.
