Applications
Niobium Nitride (NbN) powder is extensively used in superconducting applications due to its high critical temperature, excellent electrical conductivity, and ability to maintain superconductivity at cryogenic temperatures. It is a key material in the production of superconducting quantum interference devices (SQUIDs), which are essential for ultra-sensitive magnetometry and medical imaging applications such as MRI. NbN is also utilized in superconducting microwave circuits, cryogenic detectors, and single-photon detectors, where its low noise and high detection efficiency are crucial. Additionally, NbN powder is used in superconducting magnets for particle accelerators, magnetic resonance imaging (MRI) machines, and fusion reactors, thanks to its capability to support high current densities with minimal energy loss.
Niobium Nitride Powder Reference
- We report on the formation of a new metastable phase of niobium-nitride (Nb-N) alloy powders. This nonequilibrium phase has been synthesized by milling elemental niobium (Nb) powders under purified nitrogen gas flow using a high energy ball mill at room temperature. The progress of the solid-gas reaction for the Nb-N system has been followed by means of x-ray diffraction, differential thermal analysis, transmission electron microscopy, and chemical analysis. After 720 ks of milling, the initial bcc-Nb is completely transformed to nonequilibrium-fcc-NbN containing about 50 at. % N. The lattice parameter of the end product fcc-NbN was calculated to be 0.433 nm. In addition, the particle and grain sizes of the completely reacted alloy powders are 3 μm and 5 nm, respectively. This transforms to a mixture of hcp-Nb4N3 and hcp-NbN at the high temperatures, as high as 1150 K.
