11097-59-9
Product Name: Hydrotalcite
English Alias: Aluminum Magnesium Carbonate Hydroxide Hydrate; HTlc
CAS Number: 11097-59-9
Molecular Formula: Mg₆Al₂(CO₃)(OH)₁₆·4H₂O
Molecular Weight: 603.98 g/mol
Appearance: White fine powder
Package: 20 kg/bag (paper-plastic composite bag with inner PE liner)
Hydrotalcite is a layered double hydroxide (LDH) mineral with a structure similar to naturally occurring hydrotalcite. It appears as a white, odorless, fine crystalline powder. It is insoluble in water but soluble in strong acids. The compound exhibits excellent acid-neutralizing capacity, thermal stability, and anion exchange properties. It is widely used as an antacid, stabilizer, and adsorbent in pharmaceutical, polymer, and industrial applications.
Item | Index |
MgO Content | 32-35% |
Al₂O₃ Content | 18.0-21.0% |
Fe Content | 50.1 |
Heavy metal Content | 50.001 |
Loss on drying | ≤1% |
Bulk density (g/ml) | 0.2-0.3 |
Degree of whiteness | ≥90 |
pH | 7-9 |
Average particle size | 0.8 |
Dehydration start temperature | 350℃ |
Specific surface area BET | 158 |
Specific gravity of hydrotalcite | 2.1 |
Heat stabilizer:
It captures chlorine released during the thermal degradation of PVC, improving the heat stability of the material.
Environmental additive:
When mixed into agricultural plastic films, its infrared absorption properties can enhance heat retention, which helps reduce energy consumption.
Catalyst support:
It is used as a carrier for catalysts in applications like steam reforming, where it can create highly active and durable catalysts without using precious metals.
Adsorbent:
It can adsorb various anions through ion exchange.
Hydrotalcite is generally considered non-toxic and safe for pharmaceutical and industrial use. It may cause mild eye or skin irritation upon direct contact. Inhalation of dust should be avoided. Use appropriate personal protective equipment including dust mask and gloves when handling large quantities. The substance is not classified as hazardous under GHS criteria. For detailed safety information, consult the full Safety Data Sheet (SDS).
Store in a cool, dry, well-ventilated area. Keep containers tightly closed and protected from moisture. Avoid exposure to acidic environments. Maintain storage temperature below 30°C. Relative humidity below 65% recommended.
Hydrotalcite is packaged in paper-plastic composite bags with inner polyethylene liner (20 kg net weight per bag). Transport as non-hazardous material. Ensure containers are properly sealed and protected from moisture during transportation. Store away from incompatible materials.
