What does the approx. -625 mesh (2.5 μm APS) specification mean for Atomfair MoSi₂ powder?
The powder is specified as approx. -625 mesh, corresponding to a 2.5 μm average particle size (APS) grade. It is supplied as a gray metallic powder with 99.5% purity and is intended for research on fine-particle MoSi₂ applications such as high-temperature heating elements, oxidation-resistant coatings, and microelectronic contact materials.
Can this MoSi₂ powder be used for high-temperature electric-furnace heating elements and oxidation-resistant coatings?
Yes. The product is specifically intended for research on high-temperature electric-furnace heating elements for glass, steel, electronics and ceramic processing, materials heat treatment, oxidation-resistant high-emissivity coatings, microelectronic contact materials, and polysilicon shunts. Its stated melting point is 2030 °C, density is 6.26 g/cm³, and crystal structure is tetragonal.
Are COA and SDS documentation available for batch-specific verification of this MoSi₂ powder?
Yes. A Certificate of Analysis (COA) and Safety Data Sheet (SDS) can be provided upon request for batch-specific confirmation. This allows verification of purity, particle-size specification, and handling requirements before research use.
Atomfair MoSi₂ powder is a 99.5%-pure, ~2.5 µm APS tetragonal powder with a 2030 °C melting point and 6.26 g/cm³ density, suited to high-temperature furnace-element, oxidation-resistant coating, and microelectronic contact-material R&D. The material is supplied as loose powder, and batch-specific COA and SDS documentation must be requested separately.
Positive
- High Melting Point 2030 °C: The 2030 °C melting point supports research on high-temperature electric-furnace heating elements for glass, steel, electronics, and ceramic processing.
- Fine 2.5 µm APS Powder: The approximately -625 mesh / 2.5 µm APS particle size at 99.5% purity is compatible with work on oxidation-resistant high-emissivity coatings and microelectronic contact or polysilicon shunt materials.
Trade-offs
- Requires Downstream Processing: MoSi₂ is supplied as loose powder rather than a finished heating element, coating, or contact structure, so users must consolidate or apply it before evaluating end-use performance.
- Batch Verification Documentation On Request: COA and SDS are not preloaded with the product; batch-specific confirmation of purity, particle-size conformance, and handling requirements must be requested separately.
