Kaolinite is obtained by processing kaolin. Kaolinite is a clay mineral family phyllosilicate whose composition is Al 2 Si 2 O 5 (OH 4 ). Its structure consists of alternating sheets of SiO 4 tetrahedra (layer T) and alumina octahedra (layer O) joined by apical oxygen atoms (atoms not shared by SiO 4 tetrahedra) in the T layer (see Figure 3.4(a) ).
