Description
Bentonite and Fullers Earth are the commercial terms used to describe montmorillonite. Bentonite is an absorbent aluminium phyllosilicate, consisting mostly of montmorillonite.These are three layered Aluminosilicate with molecules of water between layers. For industrial purposes, two main classes of bentonite exist:
>> Sodium bentonite >> Calcium bentonite
Sodium bentonite Sodium bentonite expands when wet, possibly absorbing several times its dry mass in water. Because of its excellent colloidal properties it is often used in drilling mud for oil and gas wells and for geotechnical and environmental investigations.The property of swelling also makes sodium bentonite useful as a sealant, especially for the sealing of subsurface disposal systems for spent nuclear fuel and for quarantining metal pollutants of groundwater. In fact in all bentonites available in the world, the sodium variety has high swelling and gelling properties along with good viscosity and liquid limit.
Calcium bentonite
Calcium bentonite is a useful adsorbent of ions in solution.as well as fats and oils, being a main active ingredient of Fuller's Earth. Applications of Bentonite :-
- Oil Well Drilling
- Foundry
- Animal Feed
- Iron Ore Pellatization
- Agriculture Carrier
- Pet Litter
- Pesticides Carrier
