What does the -625 mesh (2.5 μm APS) particle-size specification mean for this MoSi2 powder?
The -625 mesh specification corresponds to an approximate average particle size of 2.5 μm, so the material is supplied as a fine gray metallic powder. The listed density is 6.26 g/cm³ and the melting point is 2030 °C, which are relevant when evaluating powder handling, dispersion, and high-temperature processing behavior.
Which application constraints or intended uses are supported by Atomfair's 99.8% MoSi2 powder?
Atomfair positions this powder for high-temperature electric-furnace heating elements in glass, steel, electronics, and ceramic processing, as well as materials heat treatment, oxidation-resistant high-emissivity coatings, microelectronic contact materials, and polysilicon shunts. The 99.8% purity grade and fine particle size are the product-specific specifications cited for these research applications.
Can batch-specific COA and SDS documentation be obtained for this powder before procurement?
Yes. A Certificate of Analysis (COA) and Safety Data Sheet (SDS) can be provided upon request for batch-specific confirmation. For specification review and quotation support, the Atomfair team can be contacted directly.
This Atomfair MoSi₂ powder, supplied at 99.8% purity as a ~2.5 μm APS gray metallic powder, is evaluated for high-temperature furnace-element, oxidation-resistant high-emissivity coating, and microelectronic contact research. Users should confirm the approximate particle-size specification and batch-specific COA before relying on the powder for trace-sensitive applications.
Positive
- Refractory high-temperature powder: With a 2030 °C melting point, tetragonal structure, and 6.26 g/cm³ density, this MoSi₂ powder is positioned for research on high-temperature electric-furnace heating elements used in glass, steel, electronics, and ceramic processing.
- 99.8% pure fine-particle feedstock: The 99.8% purity grade and approximately 2.5 μm APS particle size provide a fine, high-purity MoSi₂ feedstock for oxidation-resistant high-emissivity coatings and microelectronic contact material studies.
Trade-offs
- Approximate particle-size rating: The -625 mesh / 2.5 μm APS value is stated as approximate, so particle-size distribution should be verified against the batch COA if the application has tight sintering or coating-thickness requirements.
- Residual fraction in 99.8% grade: The 99.8% purity specification leaves a small residual fraction; for microelectronic contact or polysilicon shunt research, confirm trace-element content from the batch-specific COA before use.
