How does the particle size distribution (D10, D50, D90, D97) of this beta-SiC powder affect its suitability for precision lapping versus polishing?
The D50 of 20.0±0.2 μm, combined with D10 of 11.5±0.2 μm, D90 of 30.5±0.22 μm, and D97 ≤35 μm, provides a narrow distribution that yields consistent material removal rates. The high tap density (1.75±0.05 g/cm³) and cubic beta-SiC phase support efficient cutting and lower surface roughness, making it suitable for both lapping and polishing applications.
What crystal phase is this silicon carbide powder, and why is it chosen for abrasive processing?
The product is specified as cubic beta-SiC (3C-SiC), a phase known for its high hardness and low coefficient of friction, which is advantageous for precision grinding and polishing. The basic grain content of 60%-80% ensures a high proportion of active abrasive particles.
What documentation is available to confirm batch-specific quality and safety for this beta-SiC powder?
The manufacturer provides a Certificate of Analysis (COA) and Safety Data Sheet (SDS) upon request for batch-specific confirmation. These documents support quality assurance and safe handling in laboratory environments.
This Atomfair Beta SiC (3C-SiC) fine abrasive powder is specified at D50 20.0 ± 0.2 μm with a narrow D10/D90 distribution and tap density 1.75 ± 0.05 g/cm³, supporting controlled grinding, lapping, and polishing with improved surface finish. The cubic beta-phase material is suitable for abrasive-processing research, but custom grades and batch documentation require technical review and advance request.
Positive
- Tight particle-size distribution: D50 is specified at 20.0 ± 0.2 μm with D10 11.5 ± 0.2 μm, D90 30.5 ± 0.22 μm, and D97 ≤35 μm, providing a tightly bounded size distribution for reproducible grinding, lapping, and polishing behavior.
- High density and cubic beta-SiC phase: Tap density of 1.75 ± 0.05 g/cm³ combined with 60%-80% basic grain content of cubic 3C-SiC supports efficient abrasive cutting and lower processed-surface roughness in finishing applications.
Trade-offs
- Custom grading requires technical review: Custom particle-size or purity requirements are considered only for selected grades, and MOQ, pricing, and lead times are confirmed during technical review and quotation rather than offered as standard options.
- Documentation is only on request: COA and SDS are provided upon request for batch-specific confirmation, so documentation-dependent incoming inspection depends on requesting these records before order confirmation.
