Montmorillonite, also known as microcrystalline kaolinite or gelinite, is a silicoaluminate consisting mainly of octahedral montmorillonite particles, named after the city of Montmorillonite, France, where it was first discovered. Montmorillonite is a very soft phyllosilicate mineral that forms microscopic crystals, called clays, when they precipitate out of aqueous solutions. Montmorillonite, a member of the Montmorillonite family, is a 2:1 clay, meaning it has two tetrahedral silica sheets sandwiched between a central octahedral alumina sheet. The particles are plat-like, with an average diameter of about 1μm and a thickness of 0.96nm.
Using an electron microscope to put about 25,000 times, it is necessary to "see" individual clay particles. Members of this group include soapstone. Montmorillonite is a subclass of montmorillonite, which is a 2:1 phyllosilicate mineral characterized by an octahedral Chemicalbook charge greater than 50%. Its cation exchange capacity is due to the isomorphous substitution of Mg for Al in the central alumina plane. In this case, the substitution of lower-priced cations gives nearby oxygen atoms a net negative charge that can attract cations. In contrast, Baderite is a montmorillonite with a tetrahedral charge greater than 50%, resulting from the isomorphic substitution of Al in silica. The individual crystals of montmorillonite clay are not tightly bound, so water can intervene, causing the clay to swell. The water content of montmorillonite is variable, and its volume increases greatly when it absorbs water. Chemically, it is hydrated sodium calcium-aluminosilicate magnesium hydroxide (Na, Ca) 0.33 (Al, Mg) 2 (Si4O10) (OH) 2·nH2O. Potassium, iron, and other cations are common substitutes, and the exact proportion of cations varies from source to source. It is often mixed with chlorite, Muscovite, illite, cobalt greenstone and kaolinite.
