What do the -325 mesh and -200 mesh particle size options mean for Atomfair TaSi powder?
The powder is available as either -325 mesh or -200 mesh; a -325 mesh grade passes through a finer sieve than -200 mesh, so it is the finer particle-size option. Atomfair specifies only the mesh designation in the product description, not a numerical particle-size distribution, so the choice should be based on the mesh fraction appropriate for your process. Both grades are the same TaSi material at 99.95% purity with Ta:Si = 50:50 at.%.
What stoichiometry and purity does Atomfair TaSi powder have?
It is tantalum silicide with the chemical formula TaSi and a Ta:Si ratio of 50:50 at.%, supplied at 99.95% purity. The powder form and -325/-200 mesh options are the stated product specifications; no alternative stoichiometries or impurity profiles are listed.
What packaging sizes and ordering options are available for Atomfair TaSi powder?
The product is offered with 25 g, 100 g, and 250 g package options. Custom specifications, quantities, or packaging can be requested through the Request a Quote process, and batch-specific COA and SDS documentation is available upon request.
Atomfair TaSi powder at 99.95% purity with 50:50 at.% Ta:Si ratio, available in -325 or -200 mesh, provides consistent stoichiometry for high-temperature silicide applications requiring precise compositional control.
Positive
- High Purity (99.95%): Minimizes impurity-related defects in thin-film and contact metallization processes.
- Controlled Stoichiometric Composition: Ta:Si ratio of 50:50 at.% ensures reproducible phase formation and electrical properties.
