LABORATORY PROCUREMENT SUPPORT
For grade selection, particle-size confirmation, documentation support or custom specification review, contact our technical sales team.
Which particle-size specification should be checked when evaluating this beta-SiC powder as a thermally conductive or dielectric filler?
The Atomfair beta-SiC powder is specified with a median particle size D50 of 3.67 μm and a distribution of D10 2.27 μm, D90 5.71 μm, and D97 ≤6.62 μm, with a tap density of 1.45 g/cm³. Combined with >98% purity and low oil-absorption behavior, this defined particle profile supports evaluation in thermal-conductive filler and dielectric/insulation research.
How does the 3C-SiC crystal phase and impurity profile affect its use in microwave-absorbing and insulation applications?
The relevant basis is the cubic beta-SiC (3C-SiC) phase in a complete-crystal, low-defect powder format, which is described as providing tunable dielectric performance. Impurity limits are Fe₂O₃ <0.2%, SiO₂ <0.3%, F.Si <0.2%, and F.C <0.05%. The product is intended for microwave-absorbing materials and dielectric or insulation materials research.
What batch documentation and package configurations are available for this beta-SiC powder SKU?
Batch-specific COA and SDS can be provided upon request, and additional documentation requirements may be discussed before order confirmation. The available package sizes for this SKU are 500 g, 1 kg, and 5 kg. Contact the technical sales team for grade selection, particle-size confirmation, or custom specification review.
Atomfair Beta Silicon Carbide Powder (3C-SiC) with >98% purity and D50 3.67 μm offers a narrow particle size distribution and low-defect cubic structure, making it suitable for thermal conductivity and microwave absorption research. The documented impurity profile (Fe2O3<0.2%, SiO2<0.3%) and fixed particle size are key operational constraints for high-precision applications.
Positive
- High purity with controlled particle size: >98% purity and D50 3.67 μm with narrow distribution (D10 2.27 μm, D90 5.71 μm) ensure consistent filler performance in thermal-conductive and microwave-absorbing composites.
- Low-defect cubic beta-SiC structure: Complete-crystal, low-defect 3C-SiC with high tap density (1.45 g/cm³) and low oil absorption provides tunable dielectric properties for functional filler evaluation.
Trade-offs
- Trace impurity constraints: Impurity levels of Fe2O3 (<0.2%), SiO2 (<0.3%), and free Si (<0.2%) may limit suitability for ultra-high-purity or semiconductor-grade applications without additional purification.
- Fixed particle size limitations: Standard D50 of 3.67 μm is not adjustable for this grade; custom size requirements are subject to evaluation and may involve lead time or MOQ constraints.
