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 degrade particle surface chemistry. Processing must avoid generating airborne dust concentrations that exceed occupational exposure limits.
- Moisture Sensitivity: Store in sealed containers under dry inert gas to prevent agglomeration from ambient humidity.
- Dust Control: Use local exhaust ventilation or glovebox during transfer to minimize respirable particulate exposure.
This procedure describes safe transfer and storage of beta-SiC powder for laboratory use. Follow these steps to maintain powder integrity and minimize inhalation risk.
Required Equipment: Inert gas glovebox or fume hood, Sealed container with desiccant
- Prepare workspace
Set up the glovebox or fume hood with inert gas flow and verify absence of ignition sources. - Inspect container
Check the powder container for damage or prior moisture exposure before opening. - Transfer powder
Scoop the required amount using a clean, non-sparking spatula and immediately seal the source container. - Store remainder
Place the unused powder in a desiccated, inert-atmosphere storage cabinet away from oxidizers.
What is the significance of the D50 particle size specification of 118.0 ± 3.0 μm for this beta silicon carbide powder in advanced ceramic processing?
The D50 of 118.0 ± 3.0 μm defines the median particle size, which influences sintering behavior, green density, and final ceramic microstructure. The tight tolerance of ±3.0 μm ensures consistent batch-to-batch performance, critical for reproducible ceramic densification and properties. The specified D10 of 76.5±3.0 μm, D90 of 180.0±3.0 μm, and D97 ≤190 μm further define a narrow particle size distribution suitable for controlled processing.
How does the cubic beta-SiC (3C-SiC) phase of this powder differ from alpha-SiC phases in composite applications?
The cubic 3C-SiC phase exhibits lower thermal expansion and higher thermal conductivity compared to hexagonal alpha-SiC, making it advantageous for composite materials requiring thermal shock resistance. The equiaxed crystal morphology also promotes better dispersion in composite matrices compared to elongated alpha-SiC grains, enabling more uniform mechanical properties in the final composite.
What documentation is available to confirm the particle size distribution and safety handling of this silicon carbide powder?
A Certificate of Analysis (COA) and Safety Data Sheet (SDS) can be provided upon request for batch-specific confirmation of the particle size distribution, tap density, and handling precautions. The COA includes D10, D50, D90, and D97 values, while the SDS covers safety and storage recommendations for this cubic beta-SiC powder.
Atomfair beta Silicon Carbide Powder (3C-SiC) is supplied as a tightly specified coarse grade with D50 118.0±3.0 μm, D90 180.0±3.0 μm, D97 ≤190 μm, and tap density 1.95±0.05 g/cm3, making it relevant for advanced ceramics, composites, thermal-spray coatings, and semiconductor-related materials research. The cubic 3C-SiC phase with equiaxed grains offers the product family's good thermal conductivity and low thermal-expansion behavior, while custom particle-size and purity variants require case-by-case technical review.
Positive
- Tight coarse particle-size distribution: The D50 118.0±3.0 μm grade with D10 76.5±3.0 μm, D90 180.0±3.0 μm, and D97 ≤190 μm provides a defined coarse cut for reproducible powder feeding and packing in advanced ceramics, thermal-spray coatings, and composite processing.
- Cubic beta-SiC with equiaxed morphology: The 3C-SiC crystal structure and equiaxed grain morphology combine the product family's good thermal conductivity with low thermal-expansion behavior, supporting thermomechanically demanding research applications in coatings, composites, and semiconductor-related materials.
Trade-offs
- Custom specifications require technical review: Particle-size and purity adjustments are only evaluated upon request for selected grades; feasibility and lead time are confirmed on a case-by-case basis rather than being standard stock options.
- Coarse grade not a fine-powder substitute: This stock D50 118 μm powder is a single coarse fraction; applications requiring finer or submicron SiC depend on custom particle-size evaluation and are not covered by the listed specification.
