This powder requires controlled atmosphere storage to prevent moisture adsorption and oxidation. Particle size distribution must be verified before use in sensitive applications.
- Moisture Sensitivity: Store in a sealed container under dry inert gas to avoid agglomeration from ambient humidity.
- Oxidation Risk: Avoid prolonged exposure to air above 800°C to prevent surface oxidation of the beta-SiC particles.
- Contamination Control: Use dedicated clean tools and containers to prevent cross-contamination with other ceramic powders.
This procedure describes safe handling and preparation of beta-SiC powder for ceramic or coating applications. Proper dispersion and deagglomeration steps are critical to achieve uniform particle distribution.
Required Equipment: Glovebox or fume hood, Analytical balance, Milling jar with grinding media
- Weigh powder
Weigh the required amount of beta-SiC powder inside a glovebox under dry inert atmosphere to prevent moisture pickup. - Disperse in solvent
Transfer the powder to a milling jar and add a compatible solvent such as ethanol or isopropanol at a 1:2 powder-to-solvent ratio. - Mill to deagglomerate
Mill the slurry for 30 minutes at 200 rpm using yttria-stabilized zirconia media to break up soft agglomerates. - Dry the slurry
Dry the milled slurry in a rotary evaporator at 60°C under reduced pressure to recover the dispersed powder. - Store dried powder
Store the dried powder in a vacuum-sealed container with desiccant until ready for sintering or coating application.
What do the D10, D50, D90, and D97 values mean for Atomfair beta SiC powder with a D50 of 20 µm?
Atomfair specifies a median particle size D50 of 20.0 ± 0.2 μm, with D10 at 11.5 ± 0.2 μm and D90 at 30.5 ± 0.22 μm; D97 is stated as ≤35 μm. These distribution boundaries characterize the equiaxed powder's breadth and are directly relevant for assessing packing, flow, and consolidation behavior in ceramics, composites, and coating applications.
Is Atomfair 3C-SiC powder intended for semiconductor fabrication or only for materials research?
The product is described as suitable for advanced ceramics, composite materials, thermal-spray coatings, and semiconductor-related materials research, not as a device-grade semiconductor feedstock. Its cubic beta-SiC (3C-SiC) crystal phase and equiaxed grain morphology are the basis for these application evaluations.
What batch documentation, packaging options, and handling specifications are available for this beta-SiC powder grade?
Batch-specific COA and SDS can be provided upon request, and the product is offered in 500 g, 1 kg, and 5 kg packages. Tap density is specified as 1.75 ± 0.05 g/cm³, which is useful for estimating fill volume and handling behavior. Custom particle-size and purity requirements may be evaluated for selected grades upon request.
Atomfair Beta Silicon Carbide Powder (3C-SiC) with D50 20.0 ± 0.2 μm offers a tightly controlled median particle size and cubic beta-SiC crystal structure, suitable for advanced ceramics, thermal-spray coatings, and semiconductor materials research, though its tap density and fine particle size impose handling and processing constraints.
Positive
- Tight particle size distribution: D50 20.0 ± 0.2 μm with D10 11.5 ± 0.2 μm and D90 30.5 ± 0.22 μm ensures consistent powder behavior in sintering, coating, and composite fabrication, reducing batch-to-batch variability.
- Cubic beta-SiC crystal structure: The 3C-SiC phase provides good thermal conductivity and low thermal expansion, advantageous for thermal management in semiconductor and advanced ceramic applications.
Trade-offs
- Moderate tap density: Tap density of 1.75 ± 0.05 g/cm³ may require careful powder compaction or slurry formulation to achieve desired green density in ceramic processing.
- Fine particle handling requirements: With D50 at 20 μm and D97 ≤ 35 μm, the powder is prone to airborne dust generation, necessitating proper ventilation, dust control, and personal protective equipment during handling.
