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
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
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 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
Niobium Facts - Element Nb or Atomic Number 41 Niobium is a shiny gray, ductile metal that resembles steel It is characterized by its high melting point, considerable hardness, and low thermal and electrical conductivity compared to other conductive metals
Niobium Element Facts - chemicool. com In 1846 German chemist Henrich Rose independently discovered the element and named it niobium The metal was first isolated by Swedish scientist Christian Blomstrand in 1864 He reduced the chloride by heating it in a hydrogen atmosphere The name niobium was adopted internationally in 1950
Periodic Table of Elements: Los Alamos National Laboratory Niobium is a shiny, white, soft, and ductile metal, and takes on a bluish cast when exposed to air at room temperatures for a long time The metal starts to oxidize in air at 200°C, and when processed at even moderate temperatures must be placed in a protective atmosphere
