How does the D50 particle size distribution (D50 6.54 μm, D90 10.3 μm) affect the dielectric and thermal properties of this beta-SiC powder?
The narrow particle size distribution (D10 4.03 μm, D50 6.54 μm, D90 10.3 μm) enables consistent packing and low oil absorption, contributing to tunable dielectric performance and efficient thermal conductivity when used as a filler. The tap density of 1.65 g/cm³ supports high loading ratios.
What are the critical impurity limits in this beta-SiC powder that could affect its performance in microwave-absorbing materials?
The impurity profile specifies Fe2O3 <0.2%, SiO2 <0.2%, F.Si <0.1%, and F.C <0.05%. These controlled impurities minimize dielectric loss distortions and ensure consistent microwave absorption behavior. The >98% purity grade is maintained for reliable functional filler evaluation.
What documentation and batch-specific data are available for this beta-SiC powder to support quality assurance in research applications?
COA and SDS can be provided upon request for batch-specific confirmation. The product is supplied with a defined D50 of 6.54 μm and a complete impurity profile, allowing researchers to verify specifications before use. Additional documentation can be discussed with the technical sales team.
This Atomfair 3C-SiC powder is assessed for thermal-conductive filler, microwave-absorbing, and dielectric/insulation research: its >98% purity, complete-crystal low-defect beta-SiC format, tap density of 1.65 g/cm³, and defined D50 6.54 μm distribution provide a traceable baseline for composite formulation studies, while the 500 g, 1 kg, and 5 kg package options support lab-scale deployment.
Positive
- High-purity 3C-SiC with controlled particle size: The >98% purity grade has a documented impurity envelope—Fe₂O₃ <0.2%, SiO₂ <0.2%, F.Si <0.1%, and F.C <0.05%—along with D10 4.03 μm, D50 6.54 μm, D90 10.3 μm, and D97 ≤12.1 μm, giving researchers a defined compositional and dimensional baseline for composite experiments.
- Low oil absorption for functional filler evaluation: The stated low oil-absorption behavior, combined with tunable dielectric performance, supports evaluation in thermal-conductive filler, microwave-absorbing, and dielectric/insulation applications.
Trade-offs
- Custom specifications require confirmation: Custom particle-size and purity variants are evaluated only for selected grades upon request, so buyers must confirm any non-standard specification with Atomfair before assuming availability.
- Batch documentation is request-based: COA and SDS are provided upon request for batch-specific confirmation, so procurement and qualification workflows should request the needed documentation before order confirmation.
