En 1809, el químicu William Hyde Wollaston inglés concluyó equivocadamente que'l tantaliu y el columbio yeren idénticos. El químicu alemán Heinrich Rose determinó en 1846 que los minerales de tantaliu contienen un segundu elementu, qu'él nomó niobiu. En 1864 y 1865, una serie de descubrimientos científicos clarificó que niobiu y columbio yeren el mesmu elementu (a diferencia de tantaliu), y dende va un sieglu utilizáronse dambos nomes indistintamente. El niobiu foi adoptáu oficialmente como'l nome del elementu en 1949, pero'l nome de columbio sigue siendo d'usu corriente na metalurxa nos Estaos Xuníos. Nun foi hasta'l sieglu XX que'l niobiu foi utilizáu per primer vegada nel mercáu. Brasil ye'l principal productor de niobiu y ferroniobiu (una aleación de niobiu y fierro). El niobiu utilízase sobremanera n'aleaciones, la mayor parte n'aceru especial igual que l'utilizáu en tuberíes de gas. Anque les aleaciones contienen namái un máximu de 0,1 %, esti pequeñu porcentaxe de niobiu ameyora la resistencia del aceru. El niobiu utilizar en diversos materiales superconductores.
