LABORATORY PROCUREMENT SUPPORT
For grade selection, particle-size confirmation, documentation support or custom specification review, contact our technical sales team.
Aluminum nitride powder is moisture-sensitive and may hydrolyze upon prolonged exposure to humid air, generating ammonia. Store in a sealed, dry container under inert atmosphere to preserve purity and particle characteristics.
- Moisture Sensitivity: Minimize exposure to ambient humidity to prevent hydrolysis and ammonia generation.
- Containment Requirement: Keep the container tightly sealed when not in use to avoid moisture uptake.
- Atmosphere Recommendation: Store under dry inert gas, such as argon or nitrogen, for extended shelf life.
This procedure outlines safe handling and dispensing of aluminum nitride powder to minimize dust exposure and moisture contamination. Use appropriate personal protective equipment and work in a controlled environment.
Required Equipment: Nitrile gloves, Safety goggles, Dust mask or respirator, Spatula
- Prepare the workspace
Ensure the work area is clean, dry, and well-ventilated before opening the container. - Don protective equipment
Put on nitrile gloves, safety goggles, and a dust mask or respirator to prevent skin and respiratory contact. - Open the container carefully
Open the container slowly to avoid creating a dust cloud, and keep the lid nearby for immediate resealing. - Dispense the required amount
Use a clean, dry spatula to transfer the powder, avoiding overfilling or spilling. - Reseal the container promptly
Close the container tightly immediately after dispensing to minimize moisture absorption. - Clean the work area
Wipe down surfaces with a damp cloth to collect any residual powder, and dispose of waste properly.
What does the -300 mesh and D50 <5 μm specification mean for aluminum nitride powder performance?
The -300 mesh indicates the powder passes through a 300-mesh sieve, and D50 <5 μm means the median particle size is below 5 microns. Atomfair supplies this AlN at 99.95% purity with white to light-yellow appearance, and the product description lists thermal-management ceramics, thermally conductive polymer fillers, crucibles, LED cooling, and optoelectronic research as intended applications.
Can this aluminum nitride powder be used in both electrically insulating and thermally conductive applications?
Yes. The stated application scope includes electrical-insulation components as well as thermal-management ceramics, thermally conductive polymer fillers, LED cooling, and heat-exchange systems. Because the source lists both thermal management and electrical insulation as intended uses, this AlN powder is suited for components that require heat dissipation alongside electrical isolation.
What safety and batch documentation is available for this AlN powder?
COA and SDS can be provided upon request for batch-specific confirmation. Users should request the SDS for safety information and the COA to verify the 99.95% purity and particle specification for a specific lot.
Atomfair aluminum nitride powder with 99.95% purity and a -300 mesh, D50 <5 μm particle specification is directly applicable to thermal-management ceramics, electrically insulating components, thermally conductive polymer fillers, crucibles, LED cooling, heat-exchange systems, refractory materials, and optoelectronic research. Buyers should note that batch-specific COA/SDS confirmation and any non-standard purity or particle-size requirements must be requested through technical sales rather than assumed from the listing.
Positive
- High-purity fine-particle AlN powder: Source-listed 99.95% purity with -300 mesh and D50 <5 μm particles makes this powder suitable for thermal-management ceramics, electrical-insulation components, thermally conductive polymer fillers, LED cooling, and heat-exchange systems.
- Broad ceramic and research application scope: The same powder is positioned for crucibles, refractory materials, optoelectronic research, and polymer-filler workflows, allowing one material grade to support multiple laboratory and production use cases.
Trade-offs
- Non-standard specs require evaluation: Alternative purity, particle-size, and package requirements are only evaluated upon request, so applications outside the listed -300 mesh / D50 <5 μm specification must be confirmed through technical sales.
- Batch documentation is request-based: COA and SDS are provided upon request for batch-specific confirmation, meaning incoming quality documentation is not automatically included and must be requested for traceability.
