How does the spherical agglomerated morphology of Atomfair h-BN powder with D50 50 μm affect its packing and thermal performance in thermal interface materials?
The spherical agglomerated morphology, formed from loosely compacted hexagonal boron nitride platelets, provides a tap density of 0.4–0.6 g/cm³, which influences filler loading and thermal conductivity in TIM formulations. The 50 μm D50 particle size is optimized for balancing thermal path formation and viscosity in polymeric matrices.
What is the significance of the 0.10% water-soluble boron content in Atomfair h-BN powder for thermal interface material applications?
The water-soluble boron content is stated as 0.10%, which is a key purity metric for h-BN used in TIMs. Elevated soluble boron can introduce ionic impurities that may affect dielectric properties or long-term reliability in electronic assemblies. This specification ensures low contamination for research-grade TIM development.
What safety and handling documentation is available for Atomfair hexagonal boron nitride powder?
Atomfair provides a Certificate of Analysis (COA) and Safety Data Sheet (SDS) upon request for batch-specific confirmation. As a fine powder, standard precautions for dust inhalation and skin contact should be observed; the SDS contains detailed handling and storage recommendations.
This spherical agglomerated h-BN powder is specified at D50 50 μm with a tap density of 0.4–0.6 g/cm³ and water-soluble boron content of 0.10%, positioning it for thermal-interface-material research where controlled particle morphology and low soluble-boron content are relevant.
Positive
- Spherical agglomerated h-BN morphology: Supplied as loosely compacted hexagonal boron nitride platelets in spherical, layered agglomerates, the powder provides a defined morphology relevant for thermal-interface-material research.
- Controlled D50 and tap density: With a D50 of 50 μm and tap density of 0.4–0.6 g/cm³, the powder offers a specified particle-size and packing range that supports reproducible formulation trials.
Trade-offs
- Loose agglomerate fragility: Because the spheres are loosely compacted platelet agglomerates, mechanical handling or high-shear mixing can break down the agglomerates, altering the effective particle size and packing behavior from the stated D50 and tap density.
- Research-focused application scope: The product is intended for thermal-interface-material research; users must verify suitability for other applications beyond the stated scope.
