LABORATORY PROCUREMENT SUPPORT
For grade selection, particle-size confirmation, documentation support or custom specification review, contact our technical sales team.
This powder requires controlled atmosphere storage to prevent moisture adsorption and oxidation, which can alter particle surface chemistry and sintering behavior. Particle size distribution must be verified before use in critical applications, as deviations may affect densification and final material properties.
- Moisture Sensitivity: Store in a sealed container under dry inert gas to minimize surface hydroxylation and agglomeration.
- Particle Size Verification: Confirm D50 and distribution via laser diffraction before incorporation into formulations requiring tight particle size control.
- Contamination Prevention: Use dedicated spatulas and containers to avoid cross-contamination with other ceramic powders or metals.
This procedure covers safe handling and preparation of beta-SiC powder for ceramic or composite processing. Steps assume use of standard glovebox or fume hood with appropriate PPE.
Required Equipment: Inert-gas glovebox or fume hood, Ceramic or PTFE spatula, Sealable container with desiccant
- Inspect container seal
Verify the powder container is intact and free of moisture ingress before opening. - Transfer to glovebox
Place the sealed container inside an inert-atmosphere glovebox and allow it to equilibrate for 10 minutes before opening. - Weigh required amount
Use a clean ceramic spatula to transfer the powder into a tared, dry mixing vessel. - Reseal bulk container
Immediately reseal the bulk powder container under inert gas to prevent moisture uptake. - Proceed with formulation
Add the powder to the pre-mixed liquid or binder system and homogenize according to your process protocol.
What particle-size distribution is controlled for this 35 μm 3C-SiC powder, and how does it relate to ceramics and thermal-spray processing?
The powder is specified with a median D50 of 35.0±0.2 μm and a controlled distribution: D10 23.0±0.2 μm, D90 55.0±0.22 μm, and D97 ≤68 μm. Combined with equiaxed crystal grains and a tap density of 1.80±0.05 g/cm³, this specification is intended to support advanced ceramics, composite materials, and thermal-spray coatings. Quantitative sintering or coating performance is not stated in the source.
Can beta-phase 3C-SiC powder be used in semiconductor-related materials research and thermal-management evaluations?
Yes. This product is explicitly supplied as cubic beta-SiC (3C-SiC) and is intended for semiconductor-related materials research in addition to advanced ceramics, composites, and thermal-spray coatings. The source attributes good thermal conductivity and low thermal-expansion behavior to the product family, which can be relevant for thermal-management studies. Custom purity requirements may be evaluated for selected grades upon request.
How should the 1.80 g/cm³ tap density be interpreted when planning powder handling or downstream processing?
The specified tap density is 1.80±0.05 g/cm³, giving a quantitative reference for powder packing and volume estimates during laboratory or production handling. The equiaxed grain morphology and D10/D50/D90/D97 distribution are the associated physical parameters to check for consistency. The source does not state a green density, compaction protocol, or storage conditions, so process-specific trials should be confirmed with technical sales.
Atomfair 3C-SiC powder is specified as a cubic beta-SiC grade with D50 35.0±0.2 μm, equiaxed morphology, and a controlled particle-size spread from D10 23.0 μm to D90 55.0 μm, making it suitable for advanced ceramics, thermal-spray coatings, composites, and semiconductor-related materials evaluation.
Positive
- Controlled 35 µm D50 grade: The median particle size is tightly specified at 35.0±0.2 μm with D10 23.0±0.2 μm, D90 55.0±0.22 μm, and D97 ≤68 μm, supporting reproducible behavior in ceramic, coating, and composite processing.
- Cubic beta-SiC equiaxed powder: The 3C-SiC cubic phase with equiaxed crystal grains is suited to advanced ceramics, thermal-spray coatings, composites, and semiconductor-related materials research; the product family offers good thermal conductivity with low thermal-expansion behavior.
Trade-offs
- Custom grades need technical review: Custom particle-size and purity requirements are evaluated only for selected grades upon request, so users requiring adjusted specifications must qualify their grade through technical review before ordering.
