Niobium
HistoryNiobium, formerly known as columbium, is a chemical element with the symbol Nb (formerly Cb) and atomic number 41. Niobium is a light grey, crystalline, and ductile transition metal. Pure niobium has a hardness similar to that of pure titanium, and it has similar ductility to iron. Niobium oxidizes in the earth's atmosphere very slowly, hence its application in jewelry as a hypoallergenic alternative to nickel. Niobium is often found in the minerals pyrochlore and columbite, hence the former name quot;columbiumquot;. Its name co
Niobium Minerals amp; Production TIC
Production of raw materials. The primary mineral from which niobium is obtained is known as pyrochlore. The world's largest deposit is located in Araxa, Brazil and is owned by Companhia Brasileira de Metalurgia e Mineracao (CBMM). The reserves are enough to supply current world demand for about 500 years, about 460 million tonnes.
