Bentonite is a highly absorbent aluminium phyllosilicate clay, predominantly composed of montmorillonite, and is widely utilized across various industries. This natural clay material is created primarily from the weathering of volcanic ash, particularly when exposed to moisture. The classification of bentonite is typically based on its dominant element, including sodium (Na), calcium (Ca), and potassium (K), leading to distinct types of bentonite, each with unique properties and applications. Sodium bentonite is especially noted for its swelling capabilities, making it ideal for use in drilling fluids, while calcium bentonite is recognized for its binding properties in foundry sands. Additionally, the term

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. Bentonite usually forms from weathering of volcanic ash most often in the presence of water. However, the term bentonite, as well as a similar clay called tonstein, has been used to describe clay beds of uncertain origin. pls vist our website www.nupurmineral.com
Bentonite usually forms from weathering of volcanic ash most often in the presence of water. However, the term bentonite, as well as a similar clay called tonstein, has been used to describe clay beds of uncertain origin. For industrial purposes, two main classes of bentonite exist: sodium and calcium bentonite. In stratigraphy and tephrochronology, completely devitrified(weathered volcanic glass) ash-fall beds are commonly referred to as K-bentonites when the dominant clay species is illite. Other common clay species that are sometimes dominant are montmorillonite and Kaolinite. Kaolinite-dominated clays are commonly referred to as tonsteins and are typically associated with coal.
