_Warbixinta Niobium
Niobium waa mid iftiinka buluug ah, crystalline, birta ductile ah oo noqday superconductor at heerkulka cryogenic. Asal ahaan loo yaqaan columbium in America. Waxaa loo isticmaalaa in superconducting magnetics ee Large Hadron Collider.
Barnaamijyada
Superconducting magneties (MRI, qaybaha acceleration), birta alloys ee pipelines, matoorada jet, iyo alaabta qurxinta.
Xaqiiqo xiiso leh
Niobium-titanium alloys waxaa loo isticmaalaa superconducting magnetics ee Large Hadron Collider.
