WebDec 12, 2003 · Kaolinite is a layered silocate made of alternating sheets of octahedrally coordinated aluminum and tetrahedrally coordinated silicon that are bonded by hydroxyl groups. Kaolinite is represented by the chemical formula Al2Si2O5 (OH)4, and it most often occurs as clay-sized, platelike, hexagonally shaped crystals.

WebMontmorillonite and kaolinite are the major clay minerals in most soils. They possess different surface charge properties: montmorillonite carries almost entirely negative charge, whereas kaolinite carries both negative and positive charges (Tombacz and Szekeres, 2006 ). WebKaolin is a layered silicate mineral with a quadrilateral silica sheet, which is attached to an octagonal alumina plate by oxygen atoms. This compound is also known by other names such as kaolin, traba and Chinese clay.
