Bentonite Properties/ Specification Arij Trading

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

Sodium Based Bentonite Powder, Bentonite Mineral Powder

Sodium Bentonite Powder is a clay mineral which is largely composed of Montmorillonite, which is mainly a hydrous aluminum silicate. It is highly colloidal and plastic clay with the unique characteristic of swelling to several times its original volume when placed in water. Mining then begins by removing the overburden from the mineral deposit with the use of large earth

BENTONITE

Bentonite is an absorbent aluminium phyllosilicate clay consisting mostly of montmorillonite. The different types of bentonite are each named after the respective dominant element, such as potassium(K), sodium (Na), calcium(Ca), and aluminium (Al). Experts debate a number of nomenclatorial problems with the classification of bentonite clays.
