Bentonite
Bentonite is an absorbent clay consisting mostly of the mineral montmorillonite. It is formed by the weathering of volcanic ash, most often in the presence of water. Chemically, it is an impure form of aluminum phyllosilicate.The formula of montmorillonite may be written as (Na,Ca) 0.33 (Al,Mg) 2 Si 4 O 10 (OH) 2 ·(H 2 O) n.There are two types of bentonite: …
