What particle-size distribution does Atomfair beta SiC powder provide for thermal-conductive and microwave-absorbing formulations?
Atomfair supplies a fine 3C-SiC powder with D50 0.37 μm and a distribution spanning D10 0.08 μm, D90 0.72 μm, and D97 ≤0.9 μm. The described complete-crystal, low-defect cubic beta-SiC format with high density and low oil-absorption behavior is positioned for thermal-conductive filler and microwave-absorbing research.
Can this beta silicon carbide powder be used in dielectric/insulation research as well as microwave absorption?
Yes; the product description explicitly lists microwave-absorbing materials and dielectric or insulation materials research as application scopes. It is a >98% purity cubic beta-SiC grade with a specified impurity profile—Fe2O3 <0.2%, SiO2 <0.5%, F.Si <0.2%, F.C <0.1%—and tunable dielectric performance for functional-filler evaluation.
What documentation and custom specification options should be confirmed before ordering this 3C-SiC powder?
COA and SDS can be provided upon request for batch-specific confirmation, and additional documentation may be discussed before order confirmation. Custom particle-size and purity requirements can be evaluated for selected grades, and alternative package sizes may be available; MOQs, pricing, and lead times are confirmed during technical review.
This 3C-SiC powder, with >98% purity and a D50 of 0.37 μm, offers a defined particle size distribution and low impurity profile (Fe₂O₃<0.2%, SiO₂<0.5%) suitable for thermal-conductive filler and microwave-absorbing material research, though its fine particle size and low tap density require careful handling and dispersion optimization.
Positive
- Defined particle size distribution: D50 of 0.37 μm with D10 0.08 μm and D90 0.72 μm provides a narrow, reproducible particle size range critical for consistent filler packing and dielectric property tuning in composite formulations.
- Low impurity profile for functional fillers: Fe₂O₃<0.2% and SiO₂<0.5% minimize contamination risks in thermal and microwave applications, supporting stable dielectric and insulation performance.
Trade-offs
- Low tap density requires handling care: Tap density of 0.70 g/cm³ indicates a fluffy, low-bulk-density powder that may be prone to dusting and requires careful transfer and dispersion to achieve uniform loading in composites.
- Fine particle size complicates dispersion: Sub-micron particles (D50 0.37 μm) increase surface area and interparticle forces, necessitating effective deagglomeration and surfactant or solvent selection to avoid agglomeration in matrix processing.
