Key Characteristics of Ultrafine metal Iridium powder for catalyst IR high purity 99.99
-
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 Ultrafine metal Iridium powder for catalyst IR high purity 99.99
Iridium (Ir) is a precious metal known for its exceptional catalytic properties, especially in ultrafine forms. Ultrafine metal iridium powder with a purity of 99.99% (often referred to as 4N or 5N grade) typically has the following parameters:
1. Particle Size Distribution: Ultrafine particles usually have a diameter below 100 nanometers, often ranging from sub-10 nm to around 50 nm. This fine particle size allows for a larger surface area, which enhances the catalyst’s reactivity.
2. Purity: 99.99% pure means that the iridium content is virtually free from impurities, such as other metals or elements, which can affect the catalyst’s performance and stability.
3. Specific Surface Area: High purity iridium powders typically exhibit a high specific surface area, which contributes to the increased number of active sites for chemical reactions.
4. Crystal Structure: Iridium metal usually exists in a face-centered cubic (FCC) crystal structure. The high purity may result in a more consistent and well-defined crystal structure.
5. Density: Iridium has a density of around 22.42 g/cm³, which remains relatively constant regardless of the particle size.
6. Thermal Stability: Iridium is known for its high melting point (2443°C) and excellent thermal stability, making it suitable for high-temperature applications.
7. Chemical Resistance: Due to its strong oxidation resistance, iridium is resistant to corrosion in many chemical environments, which is crucial for catalysts.
8. Electrical Conductivity: As a transition metal, iridium exhibits good electrical conductivity.
9. Yield: The yield of the 99.99% pure iridium powder may vary depending on the production method, but it will be optimized for high purity and minimal loss during processing.
Please note that the exact parameters might vary slightly between different suppliers, and it’s essential to consult the product specifications provided by the manufacturer for the most accurate information.
