How does the D50 118 μm particle size and rounded morphology of Atomfair 3C-SiC powder affect flowability and packing?
This 3C-SiC powder is specified as high-flow beta silicon carbide with >99% purity and a regular, rounded particle morphology, providing good flowability and dense-packing characteristics. The listed particle size is D50 118 μm with D97 ≤198 μm, and tap density is 1.95 g/cm³. These characteristics support high filling density and good moldability for formulation and feedstock evaluation.
What purity and impurity limits are specified for Atomfair High-Flow Beta Silicon Carbide Powder?
Purity is specified as >99%, with an impurity profile of Fe₂O₃ <0.08%, SiO₂ <0.1%, F.Si <0.1%, and F.C <0.05%. The material is cubic beta-SiC (3C-SiC) with chemical formula SiC. A COA and SDS can be provided upon request for batch-specific confirmation.
Which applications and package sizes are supported for Atomfair 118 μm beta-SiC powder?
The stated application scope is 3D printing, ceramics, spraying, and composite-materials research. The product is available in 500 g, 1 kg, and 5 kg packages, and custom particle-size, purity, and alternative package sizes may be evaluated upon request. Minimum order quantities, pricing, and lead times vary by specification and are confirmed during technical review and quotation.
Atomfair's 3C-SiC powder combines >99% purity with a rounded, free-flowing morphology (D50 118 µm, tap density 1.95 g/cm³), making it a suitable feedstock candidate for 3D printing, ceramic forming, spraying, and composite research; however, the published D90 of 18 µm is inconsistent with the median and D97 values and should be reconciled via COA before process design.
Positive
- High-purity cubic beta SiC: Supplied at >99% purity in the 3C-SiC beta phase with low Fe₂O₃ (<0.08%), SiO₂ (<0.1%), free silicon (<0.1%), and free carbon (<0.05%) impurities, reducing contamination risk in downstream ceramic and composite formulations.
- Rounded morphology with dense packing: Regular rounded particles with good flowability and a tap density of 1.95 g/cm³ support high filling density, moldability, and consistent feedstock behavior for 3D printing, spraying, and ceramics.
Trade-offs
- Reported PSD contains data inconsistency: The datasheet lists D90 at 18 µm, which is numerically inconsistent with both D50 (118 µm) and D97 (≤198 µm); buyers should request a batch-specific COA or particle-size report to verify the actual size distribution before process scale-up.
