Bentonite

Volcanic Materials in Commerce and Industry. Jonathan Dehn, Stephen R. McNutt, in The Encyclopedia of Volcanoes (Second Edition), 2015. 5.1 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 …

The potential cutaneous benefits of bentonites and

the sheets, gives bentonites and montmorillonites its hydro-philicity and other unique properties [4]. Although the industrial uses of bentonites and montmo-rillonites are well documented, their biomedical applica-tions are still being explored. These clays have been used to treat a variety of conditions including pain, colitis, diar-

Bentonite: production, supply and uses in paint

Bentonite types. On an industrial scale there are two majorly important types of bentonites, with distinctly different bonding properties: calcium bentonite, with a low degree of swelling;; sodium bentonite, with a high degree of swelling.; While both types can be sourced naturally, it is also possible to convert calcium bentonite into sodium bentonite if needed.

[PDF] Industrial Applications of Bentonite

Bentonite is employed by industry to perform a multitude of jobs. Certain industrial applications become apparent from an understanding of the composition and structure of bentonite, and the properties they create. These properties are utilized chiefly when the material is suspended in a liquid, usually water; or as a dried powder or granule. Most industrial applications involve the …
