Hei whakamutu i tenei raruraru, i whiriwhiria te ingoa niobium mo te waahanga 41 i te 15th Conference of the Union of Chemistry i Amsterdam i te 1949. I te tau i muri mai, i whakaaetia tenei ingoa e te International Union of Pure and Applied Chemistry (IPACU) i muri i nga tau 100 o te tautohetohe, ahakoa te timatanga o te ingoa columbium. He momo taurangi tenei; i whakaaetia te whakamahinga o te IUPAC i Amerika ki te Raki hei utu mo te wolfram; i te wa e whakamahia ana te ingoa niobium mo te niobium i roto i te maha o nga umanga matū o te US me te IUPAC, me te maha o nga umanga matū me te kawanatanga o Europi: "He aha te ingoa niobium e whakamahia ana mo te niobium i te 15th Conference of the Union of Chemistry i Amsterdam i te 1949?"
