Overview of 20 um high purity ultra-fine nano iridium powder Iridium particles Iridium powder
20 um high purity ultra-fine nano iridium powder Iridium particles Iridium powder comprises a broad category of finely divided, solid particles derived from various metals or metal alloys. These powders exhibit unique characteristics that make them indispensable in modern manufacturing and advanced technologies.
Key Characteristics of 20 um high purity ultra-fine nano iridium powder Iridium particles Iridium powder
-
Particle Size and Distribution: The size and uniformity of particles significantly influence flowability, packing density, and the final product’s mechanical and physical properties. Finer powders generally offer a larger surface area, which is beneficial for reactions and sintering but may also increase aggregation.
-
Composition: Metal powders can be elemental (pure metal) or alloyed, combining two or more metals to achieve desired properties such as enhanced strength, corrosion resistance, or electrical conductivity.
-
Shape: Particle shapes range from spherical to irregular or flake-like. Spherical powders provide better flowability and packing, while flake-shaped powders are suited for coatings and electronic applications due to their unique orientation and surface area.
-
Purity: Depending on the application, metal powders can be highly purified to remove impurities, critical for uses in electronics, aerospace, and medical devices where contamination could compromise performance.

Parameters of 20 um high purity ultra-fine nano iridium powder Iridium particles Iridium powder
It seems like you’re asking for specific parameters of a 20 micron high purity ultra-fine nano iridium powder. Here are some key parameters typically associated with such a product:
1. Particle Size Distribution: Ultra-fine nano iridium powder usually has a particle size in the range of 1-100 nanometers (nm), with the specified 20 microns meaning that the larger particles in the mixture are around 20 micrometers, but the majority would be much smaller.
2. Purity: High purity refers to a minimum level of impurities, often above 99.9% or 4N (nine-nines purity). This means that the powder contains less than 0.1% impurities, primarily consisting of other elements.
3. Surface Area: Due to its nano-sized particles, the surface area per unit mass is significantly higher than in larger particle sizes, which can impact reactivity and catalytic properties.
4. Crystal Structure: Iridium is a face-centered cubic (FCC) metal, and the nano-powder might maintain this structure, although high purity could lead to fewer defects in the crystal lattice.
5. Specific Gravity: Iridium has a relatively high specific gravity of around 22.4 g/cm³, which affects its density and handling characteristics.
6. Particle Shape: Nano-powders can have irregular shapes, but they may also be spherical or have a near-spherical morphology, depending on the synthesis method.
7. Thermal Conductivity: Iridium is known for its excellent thermal conductivity, which is crucial for applications where heat transfer is important.
8. Electrical Conductivity: Like thermal conductivity, iridium is an excellent electrical conductor.
9. Stability: High purity iridium is generally resistant to corrosion, but storage conditions should be controlled to prevent oxidation.
10. Melting Point: Iridium has a high melting point of around 2443°C (4411°F).
Please note that these parameters can vary slightly depending on the manufacturer and their specific production process. To get detailed information, you should consult the product specifications provided by the supplier.
