What particle size grades and purity are available for Atomfair FeSi₂ powder?
Atomfair FeSi₂ is supplied as a gray powder at 99.9% purity in either -200 mesh or -160 mesh particle-size grades. The -200 and -160 mesh options allow selection of the appropriate sieve fraction for the intended catalysis, sensor, or thermoelectric research protocol. Custom specifications, quantities, and packaging can be submitted through the Request a Quote process.
Is Atomfair FeSi₂ powder soluble in water for wet-chemistry or slurry processing?
No, the technical specification lists Atomfair FeSi₂ powder as insoluble in water. This property should be considered when evaluating aqueous slurry handling, washing steps, or fabrication routes that involve water. Batch-specific confirmation can be obtained from the COA and SDS, which are available upon request.
What are the key physical properties and identifiers for Atomfair FeSi₂ powder?
Atomfair FeSi₂ powder has a molar mass of 119.975 g/mol, a density of 4.79 g/cm³, and a melting point of 1410 °C. It is identified by CAS number 12022-95-6 and EINECS number 234-670-2. These values are directly relevant for process calculations involving powder handling, high-temperature synthesis, or thermoelectric device fabrication.
Atomfair iron disilicide is a 99.9%-pure FeSi2 powder supplied in -200 and -160 mesh grades, with a 1410 °C melting point relevant to thermocouple and thermoelectric solar cell research as well as hydrogen oxidation and methanation catalysis; its water insolubility and limited particle-size range should be considered when designing dispersion or powder-processing workflows.
Positive
- 99.9% purity FeSi2 powder: The stated 99.9% purity and defined FeSi2 composition give researchers a high-purity powder for hydrogen oxidation and methanation catalysis, where trace impurities can alter reaction behavior.
- Two mesh grades for particle-size selection: Available in -200 mesh and -160 mesh, the powder can be matched to the particle-size requirements of welding-flux deoxidation, humidity sensor, thermocouple, or thermoelectric solar cell research.
Trade-offs
- Water-insoluble powder handling: FeSi2 is listed as insoluble in water, meaning aqueous slurry preparation is not a direct option and labs must plan for non-aqueous or dry processing.
- Limited particle-size range: Only -200 mesh and -160 mesh particle grades are specified; research needing finer or tightly controlled size distributions will require custom specification or additional milling.
