Niobium Fasteners
Niobium is a white, ductile metal that shows a light bluish tinge after prolonged exposure to air at room temperatures. It was originally named as columbium by Charles Hatchett who discovered it in 1801. In order to put an end to the confusion due to the difference in the naming of this element in different countries, IUPAC officially named it Niobium. The atomic number of niobium is 41 and it belongs to the d-block, period 5 of the periodic table. The chemical symbol of niobium is Nb.
Niobium Fastener starts to oxidize in air when subjected to high temperatures; hence the handling of the metal under high temperatures needs to be done under a protective environment to minimize oxidation. Columbite, samarskite and betafite are the ores of niobium. The main geographical areas where columbite is mined are Brazil, Russia, Nigeria and Canada.
The physical and chemical properties of Niobium Fastener are similar to tantalum. Apart from reacting with oxygen in air at high temperatures, Niobium Fastener is reactive to carbon, nitrogen, sulphur and halogens. Niobium is non-reactive to acids and moisture at room temperatures but reacts with acids at elevated temperatures. Niobium and its compounds may cause irritation to eyes and skin.
Niobium Fastener, formerly columbium, is a chemical element with symbol Nb and atomic number 41. It is a soft grey ductile transition metal.
