Properties Bentonite

Water absorption and swelling A fundamental property of bentonite is to absorb water and expand. However, not all bentonites have the same absorption capacity. Its level of hydration and swelling depends on the type of exchangeable ions contained, with different hydrophilic and solvating power. Swelling is mainly due to two factors: 1) water ...

Bentonite - Wikipedia

OverviewUsesTypesHistory and natural occurrenceSee alsoExternal links

Bentonites are used for decolorizing various mineral, vegetable, and animal oils. They are also used for clarifying wine, liquor, cider, beer, mead, and vinegar. The main uses of bentonite are for drilling mud, binder (e.g. foundry-sand bond, iron ore pelletizer), purifier, absorbent (e.g. pet litter), and as a groundwater barrier. As of around 1990, almost half of the US production of bentonite was used for drilling mud.

Bentonite - an overview ScienceDirect Topics

Bentonite is arguably the most frequently used fining agent. It is volcanic clay discovered in Wyoming. When hydrated, it can grow 20 times its size. Bentonite must be hydrated before being added to the wine or fruit juices, otherwise it would just sink to the bottom and absorb all parts of the wine and not just the particles intended.
