How does the particle size of 50-300nm in Blue Tungsten Oxide (WO2.9) affect its performance in electrochromic applications?
The broad particle size range (50-300nm) introduces a trade-off between film uniformity and surface area. Smaller particles enhance lithium intercalation kinetics and optical switching speed, while larger particles may cause light scattering and reduce transparency. The product is a research-grade nanopowder with ~99% purity, but the exact distribution within the range is not specified, so characterization is recommended for electrochromic thin film deposition.
Can Blue Tungsten Oxide (WO2.9) nanopowder be directly integrated into sol-gel processing for smart window coatings without additional surface modification?
The product is an inorganic nanopowder with ~99% purity and no specified surface treatment. Compatibility with sol-gel precursors depends on solvent choice, pH, and dispersion stability. Researchers should test dispersion in the target solvent system and may need to use surfactants or sonication to achieve stable colloids, as the source does not provide application-specific compatibility data.
What storage conditions are required to preserve the oxygen deficiency and dark blue color of WO2.9 nanopowder?
To maintain the non-stoichiometric WO2.9 phase and dark blue appearance, store the powder in an airtight container in a dry, inert atmosphere to prevent oxidation to WO3. The product is supplied in a 250 g package; after opening, minimize exposure to air and moisture. No specific temperature is given, but standard room temperature storage is adequate.
Blue Tungsten Oxide (WO2.9) nanopowder with 50-300nm particle size and high purity (~99% / 99.9%) offers a defined particle size range suitable for research applications, but the purity specification discrepancy requires clarification before ordering.
Positive
- High purity nanopowder: Listed purity values of ~99% and 99.9% indicate a high-purity material suitable for sensitive research applications where contamination must be minimized.
- Controlled particle size range: The specified 50-300nm particle size range provides a defined dimensional distribution, enabling consistent behavior in dispersion, deposition, or catalytic studies.
Trade-offs
- Purity specification discrepancy: The product description lists both ~99% and 99.9% purity without clarification, which may cause ordering uncertainty and requires verification with the supplier before use.
