Features of 99.95% niobium wire metal niobium filament per kg s
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 99.95% niobium wire metal niobium filament per kg s
Niobium, a chemical element with the symbol Nb and atomic number 41, is a superconducting metal that exhibits unique properties, particularly at very low temperatures. It has been widely used in various scientific applications due to its exceptional characteristics, such as high electrical conductivity, low magnetic field penetration, and minimal resistance when cooled below its critical temperature (around -269.3°C or 4.2 Kelvin).
A 99.95% pure niobium wire, often referred to as a niobium filament, is a highly refined material, which means it contains only a minuscule amount of impurities, typically less than 0.05%. This level of purity ensures the wire’s exceptional performance in superconducting devices and experiments. The 99.95% purity grade is crucial for maintaining the wire’s ability to conduct electricity without significant energy loss, a property that makes it ideal for applications like MRI machines, particle accelerators, and high-speed electronics.
The term “per kg” indicates the weight-based quantity of the niobium wire, which is commonly used to express the amount of material available in commercial transactions. A kilogram of this high-purity niobium wire would provide a substantial volume of the metal, suitable for fabrication into thin filaments or wires that can be easily integrated into intricate designs.
In terms of its physical properties, niobium wire is soft and malleable, allowing it to be easily shaped and formed into desired geometries. Its low density (about 8.5 g/cm³) contributes to its lightweight nature, making it an attractive choice for aerospace and other weight-sensitive industries. Niobium also possesses a relatively high melting point (2750°C), which ensures its durability during manufacturing processes.
When used as a filament, the wire’s high thermal conductivity ensures efficient heat dissipation, preventing overheating in applications where temperature control is critical. Furthermore, its non-magnetic behavior, known as paramagnetism, eliminates interference with magnetic fields, making it perfect for devices like magnetometers and SQUIDs (Superconducting Quantum Interference Devices).
Niobium wire is often used in the construction of superconducting magnets, where it forms the core of the coil, creating powerful and stable magnetic fields. In the context of quantum computing, it plays a vital role in the development of qubits, the building blocks of quantum information processing systems, thanks to its coherence properties and low susceptibility to environmental noise.
In conclusion, a 99.95% niobium wire with a per kg parameter is a premium material that combines exceptional superconducting properties with mechanical versatility. Its purity ensures optimal performance in various scientific and technological applications, ranging from medical equipment to cutting-edge research. As a result, the demand for this high-quality niobium filament continues to grow as scientists and engineers explore new frontiers in materials science and technology.
