Detailed Technical Analysis
In-depth comparison of structural, chemical, and physical properties
| Property | Montmorillonite | Bentonite |
|---|---|---|
| Chemical Formula | (Na,Ca)₀.₃₃(Al,Mg)₂Si₄O₁₀(OH)₂·nH₂O | Variable (mixed composition) |
| Crystal Structure | 2:1 layer silicate | Predominantly 2:1 structure |
| Layer Charge | 0.2-0.6 per formula unit | Variable (depends on composition) |
| Particle Size | < 2 μm (colloidal) | Variable (processed to specification) |
| Surface Area | 600-800 m²/g | 200-600 m²/g |
| pH Range | 6.5-9.5 | 8.0-10.5 |
| Thermal Stability | Up to 700°C | Variable (500-700°C) |
| Organic Modification | Excellent compatibility | Good (depends on purity) |
The Relationship Explained
Montmorillonite is the primary active component within bentonite clay. Think of bentonite as a natural clay rock that contains 70-85% montmorillonite along with other minerals like quartz, feldspar, and cristobalite. The quality and properties of bentonite are largely determined by its montmorillonite content.
