Za ine Niobium
Niobium ndi chinyezi chofiira, kristalo, cholimba cholimba chomwe chimayamba kukhala chopanda madzi pa kutentha kwa cryogenic. Choyamba chimatchedwa columbium ku America. Imagwiritsidwa ntchito mu ma magnets a superconducting a Large Hadron Collider.
Kugwiritsa ntchito & Maphunziro
Superconducting ma magnets (MRI, particle acceleration), zitsulo zosapanga dzimbiri za ma pipelines, ma jet engines, ndi zovala.
