What is the particle size distribution (D50) of this hexagonal boron nitride powder and how does it influence the ceramic board fabrication process?
The D50 particle size is 5 μm, as specified. This fine particle size with weak agglomeration, described as small thin circular platelets, facilitates uniform dispersion and compaction in boron nitride ceramic-board research, enabling higher density and improved thermal properties in the final ceramic.
What is the specific surface area (8 m²/g) of this h-BN powder and why is it important for ceramic board applications?
The specific surface area is 8 m²/g, as listed. A moderate SSA like this provides adequate surface reactivity for sintering without excessive interparticle friction, which is beneficial for achieving high-density boron nitride ceramic boards.
What is the tap density (0.4 g/cm³) of this powder and how does it affect powder handling and die filling?
The tap density is 0.4 g/cm³. This relatively low tap density indicates a fluffy powder that requires careful handling during die filling to avoid voids, but it can be compacted effectively under pressure for ceramic board fabrication.
Atomfair hexagonal boron nitride (h-BN) powder with D50 5 μm and medium crystallinity is evaluated for boron nitride ceramic-board research, offering small, thin circular platelets with weak agglomeration and a specific surface area of 8 m²/g, balanced against a low tap density of 0.4 g/cm³ and a water-soluble boron content of 0.10% that may affect purity-sensitive applications.
Positive
- Weak agglomeration for dispersion: The small, thin circular platelet morphology with weak agglomeration facilitates easier deagglomeration and uniform dispersion in ceramic matrix formulations, reducing processing time and improving homogeneity in green bodies.
- Controlled particle size and surface area: A specified D50 of 5 μm and specific surface area of 8 m²/g provide consistent packing behavior and sintering reactivity, enabling reproducible densification in boron nitride ceramic-board research.
Trade-offs
- Low tap density limits packing: With a tap density of only 0.4 g/cm³, the powder occupies a large volume per mass, requiring careful die filling and compaction optimization to achieve target green densities without excessive shrinkage during sintering.
- Water-soluble boron impurity: A water-soluble boron content of 0.10% may introduce boron leaching during wet processing or humidity exposure, potentially altering stoichiometry or contaminating co-processed materials in high-purity ceramic-board applications.
