Niobium Sheet Metal

Mining and uses for niobium are relatively new compared to common alternatives and new applications are still being discovered.

Niobium sheet metal.

Niobium sheet is the lightest refractory metal density 8 57 g cc and has a high melting temperature 2 468ºc. Niobium has a density of 8 57 gm cc. The niobium atom has a radius of 146 pm and a van der waals radius of 207 pm. Niobium also known as columbium is number 41 on the periodic table.

Nb is used in pure and alloyed form in superconductors sodium vapor lamps street lights rocket boosters and other aerospace applications. Stability stable conditions contributing to unstability nb metal is rapidly dissolved by hydrofluoric acid hydrofuoric nitric acid mixture. Niobium was discovered by charles hatchett in 1801 and first isolated by christian wilhelm blomstrand in 1864. It is a soft grey metal that is naturally found in the minerals pyrochlore and columbite.

The number of electrons in each of niobium s shells is 2 8 18 12 1 and its electron configuration is kr 4d 4 5s 1. Niobium is a chemical element symbol nb. Higher than 600ºc in nickel based alloys and as high as 1 300ºc in niobium based alloys. Niobium metal is available as disc granules ingot pellets pieces powder rod sputtering target wire and in numerous other forms and custom shapes.

Ore reserves are found in canada brazil nigeria zaire and russia. Niobium also known as columbium is a ductile metal that is most commonly used as a strong structural steel alloy. With a melting point of 2468 c it qualifies as a refractory metal. Nb ignites in cold fluorine and above 200 c will react exothermically with chlorine bromine and halocarbons such as carbon tetrachloride carbon tetrafluoride and freons.

Niobium is naturally hypoallergenic and commonly used in a number of medical devices including prosthetics and implants such as pacemakers.
