LABORATORY PROCUREMENT SUPPORT
For grade selection, particle-size confirmation, documentation support or custom specification review, contact our technical sales team.
What does the -325 mesh (4 μm APS) specification mean for this tungsten boride powder's use in coatings and thin-film research?
The -325 mesh (4 μm APS) designation indicates a fine powder with an average particle size of 4 μm at 99.5% purity. This particle size is the key process-relevant specification for the product's intended use in wear-resistant coating and semiconductor thin-film research; the listing does not provide a full particle-size distribution, so batch-specific confirmation is recommended if the application requires tighter control.
Can this tungsten boride powder be used for both wear-resistant coatings and semiconductor thin-film deposition?
Yes — Atomfair specifies this WB powder for wear-resistant coatings on wear components and for semiconductor thin-film research. It is supplied as powder with CAS 12007-09-9 and 99.5% purity, but the listing does not identify a specific coating or deposition process, so final process compatibility should be confirmed before integration.
What batch-specific documentation and safety information should be obtained before handling this WB powder?
A COA and SDS can be provided upon request for batch-specific confirmation; the SDS should be reviewed before handling because the product is supplied as a powder. For particle-size confirmation, documentation support, or custom specification review, contact the technical sales team at inquiry@atomfair.com.
Atomfair Tungsten Boride (WB) powder at 99.5% purity and -325 mesh (4 μm APS) is assessed as a fine particulate feedstock intended for wear-resistant coating development and semiconductor thin-film research, with particle-size and batch-level documentation requiring supplier confirmation.
Positive
- 99.5% purity for research applications: The specified 99.5% purity provides a defined starting assay for semiconductor thin-film research and wear-resistant coating feedstock trials.
- Fine -325 mesh / 4 μm APS powder: The -325 mesh (4 μm APS) powder form supports coating and thin-film experimental workflows that require fine particulate feedstock.
Trade-offs
- Particle-size distribution not specified: Only the nominal -325 mesh / 4 μm APS value is listed; actual particle-size distribution must be confirmed with the supplier before critical coating runs.
- Impurity balance not disclosed: The 99.5% purity value leaves a 0.5% balance whose composition is not specified, so batch-specific COA confirmation is required for sensitive applications.
