Bentonite Properties/ Specification

Bentonite is an industrial rock which is occurred naturally, identified by the feature of water-absorbing and by the capacity for Base Exchange; both features are considerably greater than that of kaolin and plastic clays. In some bentonites, water absorption is supplemented by a significant increase in volume, size, and formation of gelatinous mass. Bentonite is […]

Bentonite

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.
