1. Sodium Bentonite
High swelling capacity
Excellent water absorption
Forms a gel-like consistency in water
Used in drilling muds, sealing ponds, and construction
2. Calcium Bentonite
Lower swelling properties
Better for absorption and surface bonding
Common in cosmetics, animal feed, and pharmaceuticals
â??ï¸? Key Properties
High water absorption
Strong binding capabilities
Thixotropic (gel-like when agitated)
Chemical stability
Thermal stability
Cation-exchange capacity
