Niobium - Wikipedia Niobium is a chemical element; it has symbol Nb (formerly columbium, Cb) and atomic number 41 It is a light grey, crystalline transition metal Pure niobium has a Mohs hardness rating similar to pure titanium, [8] and it has similar ductility to iron
What is Niobium? - Vital Metals What is Niobium? Niobium (Nb) is a ductile refractory metal that is highly resistant to heat and wear It is resistant to corrosion owing to the formation of a surface oxide layer Approximately 90% of niobium use is attributed to the steel industry, predominantly as a micro alloy with iron
Niobium - Element information, properties and uses | Periodic Table The main source of this element is the mineral columbite This mineral also contains tantalum and the two elements are mined together Columbite is found in Canada, Brazil, Australia, Nigeria and elsewhere Some niobium is also produced as a by-product of tin extraction
Niobium Facts, Symbol, Discovery, Properties, Uses Niobium (pronounced as ni-OH-bee-um) belongs to the family of transition metals, denoted by the chemical symbol Nb Defined as a soft and ductile metal with eighteen isotopes, it is available in the form of foil, sheet, tube, rod, and powder
