Features of Light Yellowish Tungsten Oxide Nanoparticles 99.95%Min D50 300nm
Physical Characteristics
Particle Size: Ranging from nanometers to hundreds of micrometers, the size distribution significantly influences the powder’s flowability, packing density, and sintering behavior.
Shape: Particles can be spherical, irregular, flake-like, or dendritic, each shape affecting the final product’s mechanical properties and surface finish.
Purity: Depending on the production method, metal powders can achieve high levels of purity, critical for applications like electronics and aerospace where impurities can degrade performance.
Density: While less dense than their solid counterparts due to the presence of air between particles, metal powders can be densely packed during processing to approach the density of the solid metal.
Chemical Properties
Reactivity: Some metal powders, particularly aluminum and titanium, are highly reactive with air and moisture, necessitating careful handling and storage under inert atmospheres or vacuum.
Oxidation: Exposure to air can lead to surface oxidation, forming a passive layer that affects sintering and other processes. This can be managed through surface treatment or use of protective atmospheres.

Parameters of Light Yellowish Tungsten Oxide Nanoparticles 99.95%Min D50 300nm
Tungsten oxide nanoparticles, specifically with a light yellowish hue, boast a purity of at least 99.95%, ensuring a high-quality product for various applications. These particles possess a narrow size distribution, with a median diameter (D50) of 300 nanometers. This characteristic is crucial as it allows for efficient dispersion and uniformity in the final material, enabling them to exhibit unique optical, electronic, and catalytic properties.
The light yellowish color of these tungsten oxide nanoparticles is derived from the combination of tungsten and oxygen atoms, which gives them a distinctive visual appearance. The color can be attributed to the presence of different oxidation states of tungsten, such as tungsten(VI) oxide (WO3), which is known for its yellow or orange hues. This coloration can be advantageous in applications where aesthetic appeal or specific wavelength absorption are desired.
In terms of particle size, the 300 nanometer D50 value indicates that approximately 50% of the particles fall within this range. This nano-scale dimensionality enhances the surface area-to-volume ratio, making the tungsten oxide nanoparticles highly reactive and effective in catalytic processes, gas sensing, and optoelectronic devices. Smaller particles have a greater proportion of their atoms on the surface, which increases their reactivity and allows for improved performance in various chemical reactions.
The high purity level of 99.95% ensures minimal impurities, which is essential for maintaining the desired properties and minimizing potential side reactions. This purity also contributes to the long-term stability and reliability of the material in various industrial settings, such as in electronics, solar cells, and energy storage devices.
These tungsten oxide nanoparticles can be easily dispersed in various solvents or matrices, thanks to their uniform size distribution. This property is advantageous when incorporating them into composite materials, coatings, or ink formulations. The controlled particle size further enables tuning of the material’s properties according to the intended application, such as adjusting the light scattering or enhancing the photocatalytic activity.
In conclusion, the light yellowish tungsten oxide nanoparticles with a 99.95% purity and a median diameter of 300 nanometers offer a versatile material with exceptional performance characteristics. Their unique color, size, and purity make them suitable for a wide range of applications, from optoelectronics to environmental remediation and energy-related technologies. The ability to tailor their properties through careful processing and dispersion makes them an attractive choice for researchers and engineers seeking to harness the power of nanotechnology.
