High-purity 3N5 (99.95% Type 1/2) & High-RRR 30–300 Superconducting Electron-Beam Grade High-Purity & superconducting RRR niobium (nb) foil, sheet, rod & tube (Nb, CAS 7440-03-1) engineered for ultra-high-temperature vacuum furnaces, crystal growth, semiconductor processing, and corrosive environments.
Consolidated by powder metallurgy, vacuum arc remelting (VAR), or electron-beam melting and stress-relieved for high-temperature dimensional stability, our High-Purity & superconducting RRR niobium (nb) foil, sheet, rod & tube (Nb, CAS 7440-03-1) products deliver reliable performance in vacuum, inert-gas, and reducing furnace atmospheres.
With the highest critical temperature (Tc = 9.25 K) and lower critical field of any pure elemental superconductor, electron-beam refined niobium is central to SRF accelerator cavities, quantum circuits, and high-temperature corrosion barriers. Every shipment includes the producing mill's chemical purity Certificate of Analysis (reporting metallic and interstitial O, N, C, H trace levels in ppm) and pre-shipment dimensional verification.
