What do the -100 to -325 mesh grades mean for samarium sulfide powder, and how should I choose a mesh grade?
The mesh grades from -100 to -325 describe the sieve fraction of the Sm2S3 powder: -325 mesh is finer than -100 mesh, but the exact particle-size distribution is not stated in the product description. All grades are supplied at 99.9% purity, so the main consideration is selecting the fraction that best matches your electronic or crystalline-material research setup. For batch-specific particle-size confirmation, request the COA from Atomfair.
Why are the 1.71 eV band gap and cubic crystal structure relevant for Sm2S3 research applications?
The 1.71 eV band gap and cubic crystal structure are explicitly specified material parameters that support samarium sulfide electronic and crystalline-material research. The 99.9% purity, red-brown crystalline appearance, and CAS 12067-22-0 identity help confirm that the observed optical and structural behavior can be attributed to Sm2S3 rather than to secondary phases or contamination.
What thermal and physical properties should be accounted for when working with Sm2S3 powder?
Sm2S3 is supplied as a red-brown crystalline powder with a density of 5.87 g/cm³, a melting point of 1720 °C, and a cubic crystal structure. These values should be considered when planning high-temperature processing, densification studies, or crystalline-material experiments with the 99.9% pure powder.
Atomfair Sm₂S₃ powder is a 99.9% pure, cubic crystalline samarium sulfide supplied in -100 to -325 mesh grades; its 1.71 eV band gap and 1720 °C melting point make it appropriate for electronic and crystalline-material research, although the wide mesh window should be confirmed for applications requiring a narrow particle-size distribution.
Positive
- Defined high-purity Sm₂S₃ composition: Supplied at 99.9% purity with CAS 12067-22-0 in a red-brown cubic crystalline form, providing a clearly identified samarium sulfide material for electronic and crystalline-material research.
- Relevant solid-state physical constants: The listed density (5.87 g/cm³), melting point (1720 °C), and band gap (1.71 eV) define the material's thermal and electronic characteristics for evaluation in solid-state or semiconductor-related studies.
Trade-offs
- Broad mesh particle-size window: The -100 to -325 mesh designation covers a wide particle-size range rather than a tight distribution, so studies sensitive to grain-size uniformity should confirm the actual size fraction before use.
