KOSNANO supplies AlO(OH) boehmite nanoparticles with a crystallite size of 10–15 nm, a specific surface area above 170 m²/g, and a pore volume of 0.7–0.9 mL/g.

Our product can be evaluated for inkjet and functional coatings, battery separator coatings, catalyst carriers, and other industrial material projects that require small crystallites and high-surface-area boehmite.

• AlO(OH) material identity
• 10–15 nm crystallite size
• >170 m²/g specific surface area
• 0.7–0.9 mL/g pore volume

Key Material Properties

Our nano boehmite is AlO(OH) boehmite, not ordinary Al₂O₃ alumina powder.

Key product parameters include:

If your project is screening boehmite with small crystallites, high surface area, or a defined pore-volume range, you can use these values for an initial comparison with your current material or candidate samples.

10–15 nm Crystallite Size

The current product has a crystallite size of 10–15 nm (120 reflection).

The 10–15 nm value refers to crystallite size. It is not D50 and does not directly represent agglomerate size or laser particle-size distribution.

If your project uses D10, D50, or D90 as an acceptance criterion, tell us the target particle size and test method. We will then confirm whether the corresponding data are available.

>170 m²/g Specific Surface Area

The current nano boehmite has a specific surface area of >170 m²/g.

Together with its 10–15 nm crystallite size and 0.7–0.9 mL/g pore volume, this product can be considered as a high-surface-area boehmite candidate for material screening in coatings, catalyst carriers, and other related industrial projects.

When comparing different boehmite samples, confirm that the specific-surface-area test methods are comparable.

Pore Volume & Bulk Density

• Pore Volume: 0.7–0.9 mL/g
• Bulk Density: 0.4–0.6 g/mL

You can compare these two parameters with your current formulation or the boehmite you already use.

If your project has a defined pore-volume, bulk-density, or other acceptance requirement, include the target specification in your inquiry.

Dispersion in Monovalent Acid Systems

Available product information lists monovalent acid solutions, including nitric acid and acetic acid, as dispersion media for this nano boehmite.

If your coating or other formulation uses a related acidic system, tell us the following:

• Dispersion medium
• Solids content
• pH
• Target viscosity
• Addition method
• Other process requirements

We can use the available product information to help confirm whether the material should move forward to practical dispersion testing.

Water, alkaline systems, and other media should be evaluated separately under actual formulation conditions. Dispersion behavior in these systems cannot be inferred directly from the information for acidic systems.

Technical Specifications

Technical Note: The 10–15 nm value in the current information is the crystallite size based on the 120 reflection. It is not D50 or agglomerate size.

These values are current public reference data, not actual results from a batch COA. When comparing materials for a project, use comparable test methods and the corresponding batch information.

Applications

Inkjet & Functional Coatings

This nano boehmite can be evaluated for RC paper, PET and PP printing materials, and other inkjet or functional coating systems.

If you are developing a related coating, tell us your:

• Substrate
• Dispersion medium
• Coating system
• Target material parameters

We can use this information to confirm the current product specification and arrange samples for testing.

Battery Separator Coatings

Battery separator coating is one of the application directions listed in the current product information.

In addition to the available crystallite-size, specific-surface-area, and pore-volume data, product selection for a battery separator project should consider your particle-size distribution, impurity requirements, dispersion system, coating process, and end-use test requirements.

We recommend starting with the product data and a sample, then confirming the final specification after evaluation in the actual battery separator coating system.

Catalyst Carriers

The >170 m²/g specific surface area and 0.7–0.9 mL/g pore volume provide two directly comparable material parameters for catalyst-carrier projects.

If your project has target requirements for specific surface area, pore volume, impurities, or other carrier properties, send us your current specification for product matching.

Other Industrial Applications

Available product information also lists the following industrial application directions:

• Functional coatings
• Ceramics
• Textiles
• Papermaking

Requirements for particle size, dispersion, impurities, and processing vary by system. Final suitability should be confirmed through testing with the actual material and process.

Why Source Nano Boehmite from KOSNANO

Start with Material Parameters, Not Just a Product Name

We do more than simply call this product “nano boehmite.” You can begin with four stated parameters:

• 10–15 nm crystallite size
• >170 m²/g specific surface area
• 0.7–0.9 mL/g pore volume
• 0.4–0.6 g/mL bulk density

Use these values to judge whether the product is close to your material requirements before moving into sample testing.

Match the Material to Your Application

Coatings, battery separators, and catalyst carriers do not have exactly the same boehmite requirements.

If you already have target parameters, send us your current specification. If you are still screening materials, start with your application, dispersion medium, and target parameters.

We will use this information to discuss the appropriate next step for the current nano boehmite product.

Confirm Special Specifications Before Starting the Project

If the current reference values do not cover your project requirements, send us the target values and test methods.

KOSNANO maintains a long-term supply relationship for this product. We will confirm whether the current product or another available supply option can match your requirements.

We do not turn unverified parameters into product commitments before the data and feasibility have been confirmed.

Start with a Sample

The suitability of an industrial powder must ultimately be evaluated in the actual project system.

If the current combination of 10–15 nm crystallite size, >170 m²/g specific surface area, and 0.7–0.9 mL/g pore volume is close to your target, you can request a sample for:

• Dispersion testing
• Coating testing
• Compatibility testing
• Process evaluation

The test results can then support the next purchasing decision.

Packaging & Supply

The current public reference packaging is 25 kg/bag.

Packaging, available quantity, shipping method, and lead time for an actual order will be confirmed before quotation based on the purchase quantity and destination.

If your project has a defined schedule, include the estimated quantity and destination in your inquiry.

We will confirm the technical documents, sample options, and commercial terms available for the current product.

Frequently Asked Questions

Are boehmite and alumina the same material?

No. This product is AlO(OH) boehmite. Alumina generally refers to Al₂O₃. They have different chemical compositions, and their product parameters are not directly interchangeable.

Does 10–15 nm mean D50?

No. The 10–15 nm value in the current information refers to crystallite size based on the 120 reflection. It is not D50 and does not directly represent agglomerate size or laser particle-size distribution. If your project uses D10, D50, or D90 as an acceptance criterion, the corresponding data and test method must be confirmed separately.

What is the specific surface area of this nano boehmite?

The current reference value is >170 m²/g. When comparing materials, confirm that the test methods are comparable.

What is the pore volume?

The current reference pore volume is 0.7–0.9 mL/g. If your project uses a particular test method or target range, include it in your inquiry.

In which systems can the product be evaluated for dispersion?

Available information lists monovalent acid solutions, including nitric acid and acetic acid, as dispersion media. Other media should be tested separately under actual formulation conditions.

Can this product be used in battery separator coatings?

Battery separator coating is one of the application directions listed in the current product information. Final material selection should also consider the actual particle-size distribution, impurities, dispersion system, coating process, and end-use test requirements.

Can I request a sample?

Yes. If the current product parameters are close to your target, tell us the application direction, key parameters, sample quantity, and destination. We will confirm the sample option and available technical information.
