LABORATORY PROCUREMENT SUPPORT
For grade selection, particle-size confirmation, documentation support or custom specification review, contact our technical sales team.
What is the thermal conductivity of Sb₂Te₃ powder at room temperature and how does it affect thermoelectric device design?
The thermal conductivity is 1.65 W/(m·K) at 308 K. This relatively low value, combined with a band gap of 0.21 eV and rhombohedral hR15 structure, makes this powder suitable for thermoelectric cooling and power-generation research where efficient heat management and carrier transport are critical.
Can this 99.99% purity Sb₂Te₃ powder be used directly in thin-film deposition or must it be further processed?
The powder is supplied as -160 mesh (particle size ≤ 99 µm) and is intended for semiconductor, optoelectronic, and thermoelectric research. For thin-film deposition, it may require additional processing such as pressing into sputtering targets or evaporation pellets; the source does not specify pre-formed targets. Contact the technical sales team for custom particle-size or form-factor requirements.
What safety and handling documentation is available for this antimony telluride powder?
A Certificate of Analysis (COA) and Safety Data Sheet (SDS) can be provided upon request for batch-specific confirmation. Standard laboratory precautions for handling fine chalcogenide powders—such as use of fume hoods, gloves, and eye protection—are recommended due to the presence of antimony and tellurium.
Atomfair Antimony Telluride (Sb2Te3) Powder with 99.99% purity and -160 mesh offers a narrow band gap of 0.21 eV and low thermal conductivity of 1.65 W/(m·K) at 308 K, making it suitable for thermoelectric and optoelectronic research, but requires careful handling due to its fine powder form.
Positive
- High purity and fine mesh: 99.99% purity and -160 mesh particle size ensure consistent stoichiometry and homogeneous dispersion for reproducible research outcomes.
- Favorable thermoelectric properties: Thermal conductivity of 1.65 W/(m·K) at 308 K and a narrow band gap of 0.21 eV are well-suited for thermoelectric cooling and power-generation studies.
Trade-offs
- Powder handling precautions needed: As a fine powder, it requires appropriate laboratory safety protocols (e.g., fume hood, PPE) as indicated by the availability of an SDS for batch-specific hazard information.
- Narrow band gap limits applications: The 0.21 eV band gap restricts the material to low-energy photon detection and thermoelectric applications, limiting its use in broader semiconductor or optoelectronic research.
