Product Features
Bayerite is characterized by special crystal form, high alkali solubility, and large specific surface area of activated alumina after calcination.
Therefore, it is widely used in high-end, fine, catalytic and new material fields.
As a component of catalysts, it has a unique effect of reducing the density of acidic active sites.
Applications
1. Catalyst & Catalyst Support (Main Application)
● After calcination, it forms highly active η-Al₂O₃ / γ-Al₂O₃ with large specific surface area and controllable pore structure.
● Used in:
Petrochemical industry: hydrofining, dehydrogenation, reforming catalysts
Environmental catalysis: exhaust gas purification, VOCs treatment
Fine chemical industry: supports for organic synthesis and polymerization catalysts
2. Lithium Battery & New Energy Materials
● Precursor for lithium aluminum hydroxide, aluminum-based cathode materials, and solid-state electrolytes
● Advantages: high purity, low impurities, uniform particle size, improving cycle life and stability of batteries
3. Adsorption & Separation Materials
● High-surface-area alumina precursor used for:
Water treatment adsorbents
Gas separation, drying, desulfurization and dechlorination
Catalyst recovery and precious metal adsorption supports
4. High-End & Functional Ceramics
● Production of high-purity alumina ceramics, transparent ceramics, electronic ceramics
● Features: good sintering activity, high density, excellent electrical insulation
5. Flame Retardant Materials (High-End Special Grade)
● Halogen-free flame retardant filler for high-end plastics, epoxy resins, electronic potting compounds
● Advantages: high whiteness, good dispersion, stable flame retardant efficiency, no negative effect on electrical properties
6. Pharmaceutical & Cosmetic Raw Materials (High-Purity Grade)
● Aluminum-based pharmaceutical excipients, antacid raw materials, cosmetic adsorbent / thickening raw materials
● Requirements: ultra-high purity, low heavy metals, low sodium
