Niobium (Nb)
Opdaget i 1801 i en malm, erstattede navnet niobium officielt navnet 'columbium' i 1950 efter 100 års kontrovers.
Niobium er et blødt, skinnende hvidt, duktilt metal, der bliver blåligt ved langvarig eksponering for luft. Atten isotoper af niob er kendt.
Det findes i niobite, niobite-tantalit, parochlor og euxenit, og store aflejringer er forbundet med kulstof-silikat-bjergarter.
Niobium bruges i buesvejsningsstænger og til avancerede flyskrogsystemer, der bruges i rumfart. Dens superledende egenskaber har været med til at lave magneter, der bevarer deres superledningsevne i nærvær af stærke magnetfelter.
