Features of Niobium Pellets 99.95% Niobium Granules Grains shots Metallic Metal Target for PVD Coating
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 Niobium Pellets 99.95% Niobium Granules Grains shots Metallic Metal Target for PVD Coating
Niobium Pellets, 99.95% pure, are high-quality metallic elements that come in the form of compact and uniform granules, grains, or shots. These Nb (Niobium) targets are specifically designed for use in Physical Vapor Deposition (PVD) coating processes, an advanced technique employed in various industries, including electronics, aerospace, and semiconductor manufacturing.
PVD coatings are applied to enhance the surface properties of materials, such as wear resistance, corrosion protection, and improved electrical conductivity. Niobium, with its unique combination of high strength, low thermal expansion, and superconducting capabilities, is a sought-after material for these applications. The 99.95% purity ensures the highest quality and minimal impurities, resulting in consistent and reliable performance.
The pellets, grains, or shots of niobium are carefully processed to achieve the desired particle size and shape. This can range from sub-millimeter granules to smaller, spherical grains or larger, shot-like forms, depending on the specific requirements of the PVD system. The uniformity in size helps in achieving a more even coating thickness and minimizing defects during the deposition process.
The preparation of these niobium targets involves rigorous purification techniques, such as electrolysis or refining, to attain the exceptional 99.95% purity level. This high purity level is crucial as it minimizes contamination and improves the overall efficiency of the PVD coating process, as well as the performance of the coated components.
In PVD, the niobium pellets are typically introduced into a vacuum chamber where they are heated, causing the metal to evaporate. The resulting vapor then condenses onto a substrate, forming a thin, adherent layer. The coating parameters, such as temperature, pressure, and exposure time, are meticulously controlled to optimize the process and achieve the desired coating properties.
These parameters play a vital role in determining the final characteristics of the niobium coating. Factors like substrate material, coating thickness, adhesion, and mechanical properties are all influenced by these settings. The choice of niobium pellets as the target material allows for the creation of coatings with excellent properties, making them suitable for various applications like superconducting magnets, microelectronics, and aerospace components.
In conclusion, niobium pellets at 99.95% purity are essential components in PVD coating systems, enabling the production of high-performance materials with tailored properties. The precise control over their size, shape, and processing ensures consistent results, while the inherent qualities of niobium make it an indispensable material for modern technology advancements. By optimizing the coating parameters, manufacturers can unlock the full potential of this metallic target and contribute to the development of innovative products across multiple industries.
