Contact网页Bentonite ( / ˈbɛntənaɪt /) [1] [2] is an absorbent swelling clay consisting mostly of montmorillonite (a type of smectite) which can either be Na-montmorillonite or Ca
Contact网页Bentonite 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.
Contact网页2020年4月23日Bentonites are clay rocks made principally of smectite of the montmorillonite-beidellite series. They form mainly from the alteration of pyroclastic and/or volcaniclastic rocks. Bentonites generally form by diagenetic or hydrothermal alteration, favoured by fluids that leach alkali elements and by high Mg content.
