Montmorillonite, a member of the smectite group, is a 21 clay, meaning that it has two tetrahedral sheets of silica sandwiching a central octahedral sheet of alumina. The particles are plate shaped with an average diameter around 1 m and a thickness of 0.96 nm ; magnification of about 25,000 times, using an electron microscope, is required to quot;seequot; individual clay particles.

The higher ionic strength (imparted by the concentration of hydroxide ions) can reduce the electrostatic repulsion of the montmorillonite platelets. At high pH values, the silicate layer of the montmorillonite can be chemically digested, which further reduces the swelling potential of the clay.

A 21 clay consists of an octahedral sheet sandwiched between two tetrahedral sheets, and examples are talc, vermiculite and montmorillonite. Clay minerals include the following groups Kaolin group which includes the minerals kaolinite , dickite , halloysite , and nacrite ( polymorphs of Al 2 Si 2 O 5 (OH) 4 ).

Montmorillonite is a very soft phyllosilicate mineral that typically forms in microscopic crystals, forming a clay. It is named after Montmorillon in France. Montmorillonite, a member of the Smectite family, is a 21 clay, meaning that it has 2 tetrahedral sheets sandwiching a central octahedral sheet.
Montmorillonite mineral powder comes from purified clay particles, the result of eons of natural earth processes that create a health promoting mineral substance. Calcium Montmorillonite is a quot;speciesquot; of clay in the Smectite family and is sometimes called Bentonite.
