Niobium - WikipediaNiobium, formerly known as columbium, is a chemical element with symbol Nb (formerly Cb) and atomic number 41 It is a soft, grey, crystalline, ductile transition metal, often found in the minerals pyrochlore and columbite, hence the former name "columbium"Its name comes from Greek mythology, specifically Niobe, who was the daughter of Tantalus, the namesake of tantalumCobalt, Tantalum, Niobium, Tungsten & Molybdenum: What ,Cobalt, Tantalum, Niobium, Tungsten & Molybdenum: What Lies Ahead for Minor Metals?USGS Minerals Information: Niobium (Columbium) and TantalumNiobium and columbium are synonymous names for the chemical element with atomic number 41; columbium was the name given in 1801, and niobium (Nb) was the name officially designated by the International Union of Pure and Applied Chemistry in 1950 Niobium in the form of ferroniobium is used worldwide .What is Niobium? - Uses, Information & Facts | ,This was quite fitting because niobium is directly above tantalum, which was named for Tantalus, on the periodic table Rose gave niobium its name Up until about 1950, niobium was referred to as columbium, with the chemical symbol Cb, in the USA and Europe referred to it as niobium Eventually, scientists agreed that the element should be called niobium,Tantalum - Element information, properties and uses ,Tantalum was reported as a new metal in 1802 by Anders Gustav Ekeberg at Uppsala University, Sweden However, when William Wollaston analysed the minerals from which it had been extracted he declared it was identical to niobium which has been discovered the year previouslyColumbite-tantalite (COLTAN) >ENGINEERINGTantalite ((Fe, Mn)(Ta, Nb) 2 O 6: Iron Manganese Tantalum Niobium Oxide) is the most widespread tantalum mineral and makes for an important ore of ,Tantalum Capacitor Models | AVXAVX offers free CAD drawing of its Polymer, Tantalum, Niobium Oxide, Conformal Tantalum, Wets, and Hermetic capacitors 3D Models support the design process and allow imagination of the PCB board component layout in 3D environment All common case sizes are available in STEP format SpiTan defines the frequencyTIC - Home - Tantalum-Niobium International Study ,OBJECTIVES Increase awareness and promote the remarkable properties of tantalum and niobium Organize a general assembly of the membership in October each year for business and technical presentationsTantalum: Tantalum mineral information and dataDon't mix with the 'native' tantalum from Nizhnyi Tagil (Middle Ural) has been found to be TaC: Jedwab, J (1990): Native ruthenium in tantalum carbide concentrates from the Ural Mountains, USSRTIC Tantalum-Niobium International Study Center – ,Tantec is a member of the TIC Tantalum-Niobium International Study Center since 2012 The members of the Tantalum-Niobium International Study Center are composed of companies from the entire niobium and tantalum supply chains, from explorers to miners, traders and processors, through to end users and suppliers of ,
