Bentonite - Wikipedia
WebBentonites are used for decolorizing various mineral, vegetable, and animal oils. They are also used for clarifying wine, liquor, cider, beer, mead, and vinegar. Bentonite has the property of adsorbing relatively large amounts of protein molecules from aqueous solutions.

WebFeb 1, 2021 · What is Bentonite? Bentonite is a natural mineral mostly composed of hydrous aluminum silicates (their formula being something like Al2H2O12Si4, which means there is a basic content of Aluminum, Hydrogen and Silica). It’s usually negatively charged. Therefore, it attracts cations, like Sodium, Calcium, Iron, and Magnesium.

WebJan 1, 2013 · Definition. Bentonites are thin, widespread clay-altered ash layers that are commonly dominated by smectite ( Fisher and Schminke, 1984 ). This is the definition used by sedimentologists. Knight (1898) first used the name bentonite for an unusual clay in the Benton Shale of Cretaceous age in Wyoming.
Bentonite - an overview | ScienceDirect Topics
WebBentonite is an off-white montmorillonite clay formed from altered volcanic ash. It has a sheet-silicate structure and is especially notable for the way in which it absorbs and loses water and for its base-exchange properties. Sodic bentonite can absorb up to 10 times its own weight in water and can swell to 18 times its dry volume.
Bentonite - New World Encyclopedia
WebBentonite is an absorbent clay consisting mostly of the mineral montmorillonite. It is formed by the weathering of volcanic ash, most often in the presence of water. Chemically, it is an impure form of aluminum phyllosilicate. The formula of montmorillonite may be written as (Na,Ca) 0.33 (Al,Mg) 2 Si 4 O 10 (OH) 2 · (H 2 O) n.
