Then , it has explained that the metalniobium is used as the superconducting gyroscope rotor's material.
同时，还对用金属铌作为超导陀螺仪转子材料进行了分析和解释。

To remove dissolved oxygen in the molten metal prior to pouring, elements have been added which have high affinity for oxygen such as titanium, vanadium, niobium and magnesium.
为了在浇铸之前消除熔化金属中的溶解氧，需要在金属中添加具有很高的氧亲合力的元素，如钛，钒，铌和镁。

The existing pyrometallurgical process to prepare metalniobium is complex, expensive, energy intensive and probably polluting.
