Key Characteristics of 99.9% metals basis Nb Niobium Metal 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 99.9% metals basis Nb Niobium Metal Powder
Nb (Niobium) is a chemical element with the symbol Nb and atomic number 41. It is a lustrous, grey, strong transition metal that is often used due to its unique combination of properties, such as high strength, low thermal expansion, and excellent corrosion resistance. Here’s a general overview of some key parameters for 99.9% pure niobium metal powder:
1. Purity: 99.9% Nb – This indicates that the powder contains at least 99.9% niobium metal and less than 0.1% impurities, typically including other elements like oxygen, carbon, or nitrogen.
2. Particle Size Distribution: The powder will have a specific particle size distribution, usually specified in terms of average diameter or a range of sizes (e.g., D50, which is the median particle size). This can vary depending on the manufacturing process and application requirements.
3. Specific Gravity: Niobium has a relatively low specific gravity compared to other metals, around 8.55 g/cm³, which contributes to its lightweight property.
4. Melting Point: Niobium melts at approximately 2467°C (4474°F), which is higher than many other metals but still manageable in industrial melting processes.
5. Electrical Conductivity: Niobium is a good conductor of electricity, making it suitable for applications like superconductors where electrical resistance needs to be minimized.
6. Magnetic Properties: Niobium is non-magnetic or weakly magnetic, which is an advantage in certain applications where magnetic interference is undesirable.
7. Thermal Conductivity: Niobium has excellent thermal conductivity, which is useful for heat transfer applications.
8. Mechanical Properties: As a strong metal, niobium possesses high yield strength and modulus of elasticity, making it suitable for aerospace, nuclear, and precision engineering applications.
9. Processing Techniques: The 99.9% Nb metal powder may be produced through various techniques like gas atomization, electrochemical refining, or mechanical milling, each affecting its properties and cost.
Please note that exact values and specifications may vary depending on the supplier and the specific grade of niobium metal powder you are referring to. For more detailed information, it’s best to consult the manufacturer or a technical data sheet.
