Niobium Sheet Metal

Niobium also known as columbium is a ductile metal that is most commonly used as a strong structural steel alloy.

Niobium sheet metal.

Niobium also known as columbium is number 41 on the periodic table. Stability stable conditions contributing to unstability nb metal is rapidly dissolved by hydrofluoric acid hydrofuoric nitric acid mixture. 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. 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 was discovered by charles hatchett in 1801 and first isolated by christian wilhelm blomstrand in 1864. Niobium is a chemical element symbol nb. Niobium metal is available as disc granules ingot pellets pieces powder rod sputtering target wire and in numerous other forms and custom shapes. The niobium atom has a radius of 146 pm and a van der waals radius of 207 pm.

Ore reserves are found in canada brazil nigeria zaire and russia. It is a soft grey metal that is naturally found in the minerals pyrochlore and columbite. This property allows its alloys to provide structural solutions at high temperatures.

Ultra high purity and high purity forms also include metal powder submicron powder and nanoscale quantum dots targets for thin film deposition pellets for evaporation and single crystal. Nb is used in pure and alloyed form in superconductors sodium vapor lamps street lights rocket boosters and other aerospace applications. Higher than 600ºc in nickel based alloys and as high as 1 300ºc in niobium based alloys. Niobium has a density of 8 57 gm cc.

Niobium is naturally hypoallergenic and commonly used in a number of medical devices including prosthetics and implants such as pacemakers. Niobium sheet is the lightest refractory metal density 8 57 g cc and has a high melting temperature 2 468ºc. Mining and uses for niobium are relatively new compared to common alternatives and new applications are still being discovered.
