Dulu, Niobium sempat dinamakan "Columbium (simbol: Cb)" selama 100 tahun. Namun, pada 1949, ''International Union and Pure'' meresmikan nama "Niobium" untuk elemen ini. Niobium ditemukan pada 1801 oleh [[Charles Hatchett]].<ref>{{Cite web\|url=https://www.rsc.org/periodic-table/element/41/niobium\|title=Niobium - Element information, properties and uses {{!}}
