Boehmite Powder Manufacturer in China | OEM Supply for Ceramics & Coatings
Boehmite powder is a high-purity aluminum oxide hydroxide (γ-AlOOH) material widely used in ceramics, coatings, catalysts, and flame-retardant fillers. As one of the trusted boehmite powder manufacturers in China, BanlanChem provides OEM and bulk supply to global clients seeking stable quality, consistent particle size, and competitive pricing.
What is Boehmite Powder?
Boehmite powder, also known as γ-AlOOH, is a crystalline form of aluminum oxide hydroxide. It serves as an intermediate product in the production of activated alumina, aluminum oxide, and advanced ceramics. The unique combination of high purity, low sodium content, and controlled particle morphology makes it ideal for industries requiring precision and stability.
BanlanChem produces boehmite powder through controlled hydrothermal and precipitation processes, ensuring uniform phase purity and surface area suitable for coating and catalytic applications. Our typical grades cover particle sizes from D50 0.8 μm to 10 μm.
Key Features of BanlanChem Boehmite Powder
- High purity (>99.5% Al₂O₃)
- Low Na₂O and SiO₂ content
- Controlled particle size and BET surface area
- Excellent thermal stability and dispersibility
- Consistent phase structure and whiteness
Applications of Boehmite Powder
1. Advanced Ceramics
Boehmite powder is a key raw material for high-purity alumina ceramics and sintering additives. Its uniform particle structure ensures excellent densification and mechanical strength after calcination. BanlanChem’s boehmite improves the quality of tabular alumina and other advanced refractory components.
2. Industrial Coatings and Polishing Materials
In coating systems, boehmite for coatings acts as a binder, rheology modifier, and anti-settling agent. It enhances transparency and adhesion in high-performance coatings and provides better thermal resistance in powder coatings. It is also a fine abrasive and polishing base in alumina polishing compounds.
3. Catalysts and Catalyst Carriers
Boehmite powder is used to produce γ-alumina, a major catalyst carrier in hydrodesulfurization and petrochemical processes. Its controlled pore volume and uniform surface area ensure stable dispersion of active metals. BanlanChem supplies customized grades tailored for catalyst support formulations.
4. Flame Retardant Fillers and Electronic Materials
Because of its high whiteness and thermal conductivity, aluminum hydroxide and boehmite are often combined as flame retardant fillers in polymers and electronics. They effectively reduce smoke and heat release while maintaining insulation performance.

Boehmite Powder – Frequently Asked Questions
1) What is Boehmite Powder?
Boehmite Powder (γ-AlOOH) is a high-purity aluminum oxide hydroxide used in advanced ceramics, catalysts, industrial coatings, polishing compounds, and flame-retardant fillers. It is also a key precursor for high-purity alumina (HPA).
2) What are the advantages of Boehmite vs. Pseudoboehmite?
Boehmite offers better crystallinity, lower water content, and higher thermal stability. Pseudoboehmite features higher specific surface area and is favored for catalyst carriers and sol–gel peptization. Learn more: Pseudoboehmite Powder.
3) What is the typical purity of BanlanChem Boehmite Powder?
Our high-purity grades reach >99.5% Al2O3 equivalent after calcination, with ultra-low Na2O / SiO2 / Fe2O3. Low-sodium options are available for ceramic and battery applications.
4) What particle sizes and surface areas are available?
Standard D50 ranges from 0.8 μm to 10 μm. BET surface area can be customized to match coating rheology, catalyst dispersion, or polishing needs.
5) How does Boehmite transform during calcination?
Upon heating, Boehmite dehydroxylates to γ-Al2O3, and with higher temperature/time may transition to δ/θ and α phases—ideal when your process requires Calcined Alumina or Tabular Alumina.
6) Any dispersion tips for coatings or slurries?
Use neutral to mildly alkaline systems; add powder gradually under high-shear mixing or bead milling. For waterborne coatings, choose low-Na2O grades to reduce conductivity and gel risk. See: Alumina for Coating.
7) What packaging and storage options are available?
Standard packs: 25 kg PE bags or 500 kg jumbo bags. Store sealed in a cool, dry place to avoid moisture pickup. Shelf life: 12 months unopened under proper conditions.
8) Do you provide OEM / private label service?
Yes. We support OEM/ODM (bag type, labels, pallets, outer carton) and can tailor particle size and BET to your spec. Contact us: BanlanChem Contact.
9) Can I get samples and technical documents?
Free routine samples (freight collect) are available with TDS/COA. MSDS and compliance statements (e.g., REACH/RoHS) on request.
10) What are the lead time and shipping terms for bulk orders?
Typical lead time is 7–15 days depending on grade/volume. EXW/FOB/CIF/DDP terms supported. For quotations and schedules, please use our inquiry form.
