Preparation of Ultra High Purity Niobium for Superconductors

铌及其某些合金表现出超导性。它们在发电、推进装置、核聚变研究和电子装置中具有重要的应用价值。其他潜在的应用包括超灵敏磁传感器、用于聚变能的高磁场磁体、医疗设备、磁悬浮车辆和高速计算机。由于使用量的增加，预计在不久的将来对超高纯度铌的需求将显著增长。本研究探讨了电磁悬浮生产超纯铌的经济可行性和纯度要求。

Niobium and some of its alloys exhibit superconductivity. They are of great interest for power generation, propulsion devices, fusion research and electronic devices. Other potential applications include ultrasensitive magnetic sensors, high field magnets for fusion energy, medical equipment, magnetically levitated vehicles, and high-speed computers. Due to increasing use, the demand for ultra high purity niobium is expected to grow significantly in the near future. This research addresses the viability of electromagnetic levitation for producing ultra pure niobium economically and of the purity required.
