Taupānga
1. Ko te Niobium he mea tino nui te superconducting ki te whakaputa i te punga kaha-nui.
2. Ka whakamahia ano te paura Niobium ki te whakaputa tantalum.
3. Ko te paura whakarewa Niobium parakore, ko te Niobium Nickel alloy ranei ka whakamahia hei hanga Nickel, Chrome me te rino turanga teitei teitei.
4. Te taapiri i te 0.001% ki te 0.1% Niobium paura hei whakarereke i nga ahuatanga miihini o te maitai 5. Ka whakamahia hei taonga hiri o te ngongo arc.
