WebThis ability to exchange platelet counter ions to control clay dispersion characteristics, is a key feature of smectites. Smectite clays are defined to be swellable due to delamination in water. Hectorite and bentonite are different clay minerals but they both are members of the smectite clay family. A Hectorite clay is obtained when some magnesium WebIons and molecules adsorbed on the clay mineral surface exert a major influence on the thickness of the adsorbed water layers and on the nature of this water. The nonliquid water may extend out from the clay mineral …
