How does the narrow particle size distribution (D10=1.94 μm, D50=3.5 μm, D90=5.8 μm) of this beta-SiC powder influence achievable surface finish in lapping applications?
The narrow distribution with D50 3.5 ± 0.2 μm and D97 ≤ 7.0 μm ensures consistent cutting action. The high natural bulk density (tap density 1.45 ± 0.05 g/cm³) and efficient abrasive-cutting behavior contribute to lower processed-surface roughness and improved surface-finish performance, as stated in the product description.
What distinguishes cubic beta-SiC (3C-SiC) from alpha-SiC for precision grinding and polishing of hard materials?
Beta-SiC (3C-SiC) has a cubic crystal structure that provides different fracture characteristics and self-sharpening behavior, which can lead to more efficient cutting and finer finishes. The product's basic grain content is 60%-80%, and it is specifically designed for controlled grinding, lapping, and polishing evaluation.
What batch-specific documentation is available to confirm particle size and purity for this beta-SiC powder?
A Certificate of Analysis (COA) and Safety Data Sheet (SDS) can be provided upon request for batch-specific confirmation of particle size and purity. Additional documentation requirements may be discussed before order confirmation, as noted in the product description.
Atomfair 3C-SiC beta silicon carbide fine abrasive powder is supplied at a D50 of 3.5 ± 0.2 μm with D90 of 5.8 ± 0.5 μm and tap density of 1.45 ± 0.05 g/cm³, and is specified for precision grinding, lapping, polishing, and abrasive-processing research; the combination of controlled particle-size distribution and high bulk density supports surface-finish work with defined cutting behavior.
Positive
- Controlled abrasive particle-size distribution: D50 of 3.5 ± 0.2 μm, D90 of 5.8 ± 0.5 μm, and D97 ≤7.0 μm define a bounded distribution for precision grinding, lapping, and polishing, supporting lower processed-surface roughness and improved surface finish.
- High bulk density for cutting performance: Tap density of 1.45 ± 0.05 g/cm³ and high natural bulk density contribute to efficient abrasive-cutting behavior during abrasive-processing research.
Trade-offs
- Basic grain content specified as a range: Basic grain content is listed as 60%-80%, so the proportion in the primary grain fraction can vary by batch; users requiring a tighter effective grain distribution should request batch-specific COA confirmation.
- Custom specifications are not guaranteed: Custom particle-size and purity requirements are evaluated only for selected grades upon request, so availability and final specification limits must be confirmed through technical review before ordering.
