- Complete-crystal, low-defect cubic beta-SiC powder format with high density.
- Low oil-absorption behavior with tunable dielectric performance for functional filler evaluation.
APPLICATION SCOPE: thermal-conductive fillers, microwave-absorbing materials, and dielectric or insulation materials research
DOCUMENTATION: COA and SDS can be provided upon request for batch-specific confirmation. Additional documentation requirements may be discussed before order confirmation.
LABORATORY PROCUREMENT SUPPORT
For grade selection, particle-size confirmation, documentation support or custom specification review, contact our technical sales team.
What particle size distribution and tap density are specified for Atomfair beta silicon carbide powder with D50 19 μm?
The specified particle size distribution is D10 11.5 μm, D50 19 μm, D90 30.5 μm, and D97 ≤35.3 μm, with a tap density of 1.75 g/cm³. This well-defined micron-scale distribution is directly relevant for evaluating filler packing, oil absorption, and dielectric behavior in functional material research.
Can this 3C-SiC beta silicon carbide powder be used for both thermal-conductive and microwave-absorbing material research?
Yes. The product is explicitly intended for thermal-conductive fillers, microwave-absorbing materials, and dielectric or insulation materials research. Its cubic beta-SiC (3C-SiC) phase, >99% purity, and low oil-absorption behavior with tunable dielectric performance are cited as the relevant enabling characteristics.
What safety and batch documentation is available for this beta SiC powder before ordering?
A Certificate of Analysis (COA) and Safety Data Sheet (SDS) can be provided upon request for batch-specific confirmation. Additional documentation requirements may also be discussed before order confirmation, allowing institutional buyers to verify grade, purity, and handling data prior to commitment.
With a D50 of 19 μm, >99% purity, and cubic beta-phase crystal structure, this 3C-SiC powder presents a defined material baseline for thermal-conductive, microwave-absorbing, and dielectric filler research. Its dense, low-defect morphology and low oil absorption support filler evaluations, but batch-specific COA/SDS confirmation and custom-grade technical review are required before deployment.
Positive
- High-purity 3C-SiC with low impurity profile: At >99% purity with Fe₂O₃<0.08%, SiO₂<0.1%, F.Si<0.1%, and F.C<0.05%, the powder provides a defined baseline for thermal-conductive, microwave-absorbing, and dielectric filler evaluations.
- Dense, low-defect beta-SiC powder: The complete-crystal cubic phase with a tap density of 1.75 g/cm³ supports high packing density, while low oil absorption and tunable dielectric performance are advantageous for functional filler testing.
Trade-offs
- Batch-specific COA/SDS confirmation needed: Documented purity and impurity profiles must be confirmed for each batch via the certificate of analysis; COA and SDS are only provided upon request before the powder is accepted for critical application testing.
- Custom grades only by technical review: Custom particle-size and purity requirements are evaluated only for selected grades and require technical review and quotation, so off-specification requests cannot be assumed available.
Every advanced material, component, equipment, and instrument in our catalog is backed by rigorous testing. We maintain strict internal quality management frameworks and align with CE conformity metrics to deliver transparent, reproducible performance data via our public open-science repository.
