Bentonite is a mixture of clayey minerals, in which smectite is the main mineral and proved to be the most important one for swelling. The structure of smectite like montmorillonite is composed of two structural units, the silica tetrahedron and the alumina octahedron. These units are interconnected and extend to form layers only about 10 Å thick.
