Montmorillonite - an overview | ScienceDirect Topics

Montmorillonite. Montmorillonite are the main composition of clay minerals in sediment and suspended particulate matter, and the soil or sediment containing montmorillonite clay are recognized as good adsorbents owing to the existence of varies active sites such as the surface- and ion-exchange sites (Saeedi et al., 2013).

Clay mineral - Origin | Britannica

Clay mineral - Clay mineral - Origin: All the clay minerals, with the possible exception of halloysite, have been synthesized from mixtures of oxides or hydroxides and water at moderately low temperatures and pressures. Kaolinite tends to form in alumina-silica systems without alkalies or alkaline earths. Illite is formed when potassium is added to such systems.
