Parameters of 20-100nm nano Bismuth Bi powder ( Bi Bismuth metal powder)99.99%
Bismuth (Bi) powder with a particle size range of 20-100 nanometers (20-100 nm) and a purity level of 99.99% typically has the following parameters:
1. **Particle Size Distribution:** The powder consists of particles that fall within the specified range of 20 to 100 nanometers, meaning it is a fine nanoscale dispersion.
2. **Purity:** The 99.99% purity indicates that the powder contains less than 0.01% impurities, making it highly pure and suitable for various applications where high purity is essential.
3. **Crystal Structure:** Bismuth is a metallic element, so it generally exists as a metallic crystal structure at this scale, with a face-centered cubic (FCC) or hexagonal close-packed (HCP) arrangement, depending on the specific allotrope.
4. **Surface Area:** Due to its nanoscale nature, the surface area per unit mass is significantly higher compared to bulk bismuth, which can enhance reactivity and catalytic properties.
5. **Density:** Bismuth has a density of around 9.78 g/cm³, but at the nanoscale, it may exhibit some variations due to surface effects.
6. **Melting Point:** Bismuth’s melting point is 271.4°C (520.5°F), but this value may change slightly in the nanoform due to surface energy effects.
7. **Thermal Conductivity:** Nanosized bismuth will have lower thermal conductivity than bulk bismuth due to the increased surface-to-volume ratio and phonon scattering.
8. **Optical Properties:** Depending on the preparation method, the nanostructured Bi powder might show unique optical properties like surface plasmon resonance or enhanced absorption in the visible light spectrum.
9. **Magnetic Properties:** Bismuth is diamagnetic, meaning it weakly repels magnetic fields. However, in the presence of nanoparticles, the magnetic behavior could be influenced by size and shape effects.
10. **Applications:** This high-purity nano Bi powder finds applications in various fields such as electronics (e.g., thermoelectric devices), medicine (nanostructured drug delivery), catalysts, and optoelectronics.
Please note that the exact values for some parameters might vary depending on the manufacturer and the specific processing conditions. To obtain precise details, consult the product data sheet provided by the supplier.
