What does the D50 of 10.3 μm and the full particle size distribution mean for using this 3C-SiC powder as a thermal-conductive filler?
D50 10.3 μm is the median particle size, with D10 6.02 μm, D90 17.3 μm, and D97 ≤19.6 μm defining the distribution. Together with >99% purity, cubic beta-SiC (3C-SiC) structure, and tap density 1.70 g/cm³, this provides a defined, complete-crystal, low-defect powder intended for thermal-conductive filler evaluation. The low oil-absorption behavior also supports high filler loading in composite formulations.
Can this beta silicon carbide powder be used in both microwave-absorbing and dielectric/insulation research?
Yes. The product is specifically described as intended for thermal-conductive fillers, microwave-absorbing materials, and dielectric or insulation materials research. The cubic beta-SiC (3C-SiC) crystal phase, >99% purity, and tunable dielectric performance are the properties supporting these application areas.
What batch-specific documentation is supplied with this 3C-SiC powder for laboratory procurement?
COA and SDS can be provided upon request for batch-specific confirmation. Additional documentation requirements may be discussed before order confirmation, and custom particle-size, purity, and package-size requests are evaluated upon request.
Atomfair's 3C-SiC beta silicon carbide powder is supplied at >99% purity with a D50 of 10.3 μm and fully stated D10/D50/D90/D97, tap-density, and impurity data, making it directly assessable for thermal-conductive, microwave-absorbing, and dielectric/insulation filler research. The main operational caveat is that custom particle-size or purity adjustments are evaluated only for selected grades and must be confirmed via technical review.
Positive
- Certificate-grade purity with impurity caps: The >99% purity grade is bounded by explicit maxima for Fe2O3 (<0.08%), SiO2 (<0.1%), free Si (<0.1%), and free C (<0.05%), giving formulators a defined chemical baseline for thermal-conductive and dielectric-filler evaluations.
- Fully characterized particle-size distribution: D10 6.02 μm, D50 10.3 μm, D90 17.3 μm, D97 ≤19.6 μm, and tap density 1.70 g/cm³ are all specified for this 3C-SiC lot, enabling packing and loading assessments before composite preparation.
Trade-offs
- Custom grades limited to selected variants: Custom particle-size and purity requirements are only evaluated for selected grades upon request; users requiring a different D50 or purity must confirm feasibility through technical review before order confirmation.
