What particle-size distribution and tap density should be expected for Atomfair beta SiC powder with D50 4.5 μm?
The supplied grade is specified as D10 2.8±0.4 μm, D50 4.5±0.5 μm, D90 7.15±0.45 μm, and D97 ≤8.5 μm, with a tap density of 1.63±0.05 g/cm³. Atomfair describes the powder as having equiaxed crystal grains and a cubic beta-SiC (3C-SiC) structure. These particle-size parameters define the grade for advanced ceramics, coatings, composites, and semiconductor-related materials evaluation.
Which application areas is this beta-SiC (3C-SiC) powder intended for?
Atomfair specifies this 3C-SiC powder for advanced ceramics, composite materials, thermal-spray coatings, and semiconductor-related materials research. It is supplied with a cubic beta-SiC (3C-SiC) crystal phase and a controlled D50 4.5±0.5 μm particle-size grade. The stated application scope is limited to these research and materials-evaluation areas.
Can custom particle size, purity, or package size be requested for this SiC powder?
Custom particle-size and purity requirements may be evaluated for selected grades upon request, and alternative package sizes may also be available. Minimum order quantities, pricing, and lead times vary by specification and are confirmed during technical review and quotation. Standard package options for this listing are 500g, 1kg, and 5kg.
Atomfair Beta Silicon Carbide Powder (3C-SiC) with D50 4.5 ± 0.5 μm provides a controlled cubic beta-SiC particle size distribution suitable for advanced ceramics, thermal-spray coatings, and semiconductor materials research, though its tap density and fine particle handling require careful processing infrastructure.
Positive
- Controlled particle size distribution: D50 4.5 ± 0.5 μm with D10 2.8±0.4 μm, D90 7.15±0.45 μm, and D97 ≤8.5 μm ensures consistent powder behavior for sintering, coating, and composite formulation.
- Cubic beta-SiC crystal structure: The 3C-SiC phase provides good thermal conductivity and low thermal expansion, advantageous for thermal management in advanced ceramics and semiconductor-related applications.
Trade-offs
- Moderate tap density: Tap density of 1.63 ± 0.05 g/cm³ may require compaction optimization or binder systems for dense green-body formation in ceramic processing.
- Fine particle handling requirements: Sub-10 μm particle size (D97 ≤8.5 μm) necessitates dust control measures and proper ventilation during handling to avoid inhalation exposure and cross-contamination.
