β-Silicon Carbide Powder 3C-SiC D50 13μm Grade ATOMFAIR®

This powder requires controlled atmosphere storage to prevent moisture adsorption and oxidation, which can alter particle surface chemistry. Processing must avoid contamination from metallic or organic sources to preserve phase purity and sintering behavior.

• Moisture Sensitivity: Store in sealed containers under dry inert gas to minimize moisture uptake that can affect dispersion and sintering performance.
• Contamination Risk: Use dedicated ceramic or polymer tools during handling to prevent cross-contamination from metal ions that may degrade electrical properties in semiconductor applications.
• Dispersion Requirement: Achieve uniform particle distribution in liquid media using appropriate surfactants or mechanical agitation to avoid agglomeration during coating or casting processes.

This procedure outlines safe and effective handling of beta-SiC powder for laboratory-scale ceramic or composite preparation. Steps assume use of standard glovebox or fume hood equipment to maintain powder integrity.

Required Equipment: Inert-gas glovebox or fume hood, Ceramic mortar and pestle or ball mill, Analytical balance, Sealed storage container with desiccant

1. Prepare Work Area
   Purge the glovebox with dry argon or nitrogen to maintain oxygen and moisture levels below 1 ppm before opening the powder container.
2. Weigh Powder
   Transfer the required amount of powder into a pre-weighed ceramic crucible using a clean stainless steel spatula, minimizing exposure to ambient air.
3. Deagglomerate Powder
   Gently grind the powder in a ceramic mortar for 2–3 minutes to break up soft agglomerates without fracturing primary particles.
4. Disperse in Liquid Medium
   Add the deagglomerated powder to the liquid phase while stirring at 500–800 rpm, then sonicate for 10 minutes to achieve a homogeneous suspension.
5. Store Residual Powder
   Seal the original container immediately after use and return it to a desiccator or inert-atmosphere cabinet to prevent moisture absorption.

Atomfair's beta-SiC (3C-SiC) powder in the 13.0 ±1.2 μm D50 grade combines a controlled particle-size distribution (D10 8.35 ±0.35 μm, D90 18.4 ±2.6 μm, D97 ≤23 μm) with equiaxed cubic morphology and 1.72 ±0.05 g/cm³ tap density, making it a defined feedstock for advanced ceramics, composites, thermal-spray coatings, and semiconductor-related materials evaluation. The variable 500g/1kg/5kg package logic supports staged procurement as a single product line.

Positive

• Defined median particle-size grade: D50 13.0 ±1.2 μm with stated D10/D90 tolerances and controlled powder consistency gives laboratories a reproducible particle-size basis for ceramic, composite, and thermal-spray trials.
• Beta-SiC thermal properties: The 3C-SiC structure and equiaxed crystal morphology are paired with good thermal conductivity and low thermal-expansion behavior in the product family, supporting semiconductor-related materials research and thermal-management evaluations.

Trade-offs

• Coarse fraction to D97 ≤23 μm: The stated distribution extends to D97 ≤23 μm with D90 18.4 ±2.6 μm, so processes sensitive to coarse particles in coatings or sintered parts should verify performance or specify a tighter classified grade.
