Subcategory: Clay

Key Words: (Na,Ca) (Al,Mg)6(Si4010)3(OH)6-nH20, Montmorillonite, Smectite, Sodium montmorillonite (Sodium bentonite (Wyoming bentonite (US)), Swelling bentonite (Western bentonite (US), Sodium-activated bentonite (Bentonitte (UK)), Sodium-exchanged bentonite, (Synthetic bentonite)), Calcium montmorillonite (Calcium bentonite (Mississippi bentonite (US)), Sub-bentonite (Texas bentonite (US)), Magnesium montmorillonite (Saponite & Armargosite), Potassium montmorillonite (Metabentonite), and Lithium montmorillonite (Hectorite))

Material Notes:
Description: A clay mineral having a 2:1 expanding crystal lattice. Isomorphous substitution gives the various types and causes a net permanent charge balanced by cations in such a manner that water may move between the sheets, giving reversible cation exchange and very plastic properties. Crystals expand to many times their volume when added to water.
Uses: Used to slow the progress of water through soil or rocks; Used in drilling muds to give the water greater viscosity; Used to produce nanocomposites: Used as an absorbent to purrify and decolor liquids; Used as a filler in paper and rubber; and used as a base for cosmetics and medicines. Physical Properties Available: Powder
