Features of HRNB Pure Nb Metal Niobium Per Kg with lump powder
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 HRNB Pure Nb Metal Niobium Per Kg with lump powder
HRNB, short for High Purity Niobium, is a specific grade of niobium metal that is widely used in various industries due to its exceptional properties. Niobium, with the chemical symbol Nb, is a silvery-gray transition metal found naturally in the Earth’s crust. It is known for its high thermal and electrical conductivity, low magnetic susceptibility, and excellent mechanical strength, which make it a sought-after material in cutting-edge technologies.
The purity level of HRNB niobium is a critical factor, as it directly affects the performance and quality of the final products. Typically, the purity of HRNB niobium is measured to be 99.99% pure or higher, ensuring a minimal presence of impurities such as iron, oxygen, and carbon. This high level of purity enables HRNB niobium to exhibit superior corrosion resistance and a high degree of chemical stability.
When it comes to the form, HRNB niobium can be supplied in different forms, including lump powder. Lump powder, also known as granular niobium, consists of solid particles of the metal without any specific shape or size. The particle size in HRNB lump powder is usually uniform, facilitating easier handling, storage, and processing compared to larger ingots or bars. The powder form is often preferred in applications where fine grain structure is desired, such as in advanced materials for superconductors or aerospace components.
The parameters for HRNB pure niobium lump powder typically include:
1. Chemical Composition: As mentioned, the key parameter is the high purity level, usually above 99.99%. Other trace elements present would be within strict specifications to maintain the desired purity.
2. Particle Size Distribution: The lump powder should have a narrow particle size distribution to ensure consistency in processing. This can be specified as a range, such as 45-106 microns or another suitable measurement.
3. Density: HRNB niobium has a density of around 8.55 g/cm³, which is essential for calculating weight per unit volume.
4. Purity Analysis: The purity is usually verified through analytical techniques like Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) or Electron Probe Microanalysis (EPMA) to confirm the metal’s composition.
5. Microstructure: HRNB niobium exhibits a highly ordered crystal structure, which contributes to its unique properties. This microstructure may be characterized through techniques like X-ray diffraction (XRD).
6. Mechanical Properties: Although lump powder might not have specific mechanical properties, the manufacturer would provide data on hardness, tensile strength, and ductility, ensuring suitability for intended applications.
7. Thermal Conductivity: Niobium is known for its high thermal conductivity, which is crucial in applications like heat sinks, thermoelectric devices, and cryogenic systems.
8. Surface Finish: The surface finish of the lump powder can vary depending on the manufacturing process but may be specified as Ra () value for smoother particles.
In summary, HRNB pure niobium lump powder is a high-quality material characterized by exceptional purity, well-controlled particle size, and desirable properties for various industrial applications. Its purity, combined with the ease of processing in the powder form, makes it a versatile choice for industries ranging from electronics to energy production and aerospace engineering.
