O čistom metalu niobijuma (Nb) i legure niobijuma

Niobij, poznat i kao Columbium, je sjajni sivi ili srebrno duktilni metal koji ne tamni i ne oksidira na sobnoj temperaturi. Niobijum reaguje sa kiseonikom i halogenima samo kada se zagreje. Niobij je manje otporan na koroziju od tantala na visokim temperaturama. Niobijum ne napada azotna kiselina do 100 ° C, ali agresivno napadnut mješavinom dušične i fluorovodonične kiseline. Hot, koncentrovana hlorovodonična, sumporna, a fosforne kiseline ga napadaju, ali vruće, koncentrovana azotna kiselina ne.

Većina kiselina na niobij ne utiče na sobnoj temperaturi. Napadaju ga alkalni rastvori u određenoj meri na svim temperaturama. Zbog malog poprečnog presjeka hvatanja termalnih neutrona, Niobij ima primenu u nuklearnoj industriji. Niobij se može električno grijati i anodizirati u široku paletu boja što ga čini vrlo atraktivnim u industriji nakita. Niobijum se dodaje gvožđu ili niklu za proizvodnju legura u vazduhoplovstvu, medicinske i elektronske industrije.

What are the primary uses of Niobium?

Aplikacija: used in aerospace applications (i.e. rocket boosters), sodium vapor lamps, and superconductors. Niobium is used in the manufacture of synthetic diamonds; in sputtering targets for fiber optic applications or architectural glass; in nickel based superalloys; and alloyed with titanium or tin, in superconductors. In nuclear reactors it has low thermal neutron cross section and superior corrosion resistance, It is an excellent getter and finds use in high temperature vacuum furnaces, and is resistant to attack by the molten alkali metals found in sodium vapor lamps.

How does Niobium benefit steel production?

At atmospheric pressure, it has the highest critical temperature of the elemental superconductors. Niobium has the largest magnetic penetration depth of any element. High-energy physics researchers use some electron accelerators that include chambers cast from pure or alloyed niobium.

What medical applications does Niobium have?

Niobium is used as an alloying agent and for jewelry. Other uses include adding small amounts to improve stainless steel, as an alloying agent in carbon and alloy steels and in non-ferrous metals to improve strength. It is key element in manufacturing jet engines and rockets.

Is Niobium a refractory metal?

Da, Niobium is malleable, weldable, machinable and formable.

What superconductor applications is Niobium well suited for?

When chilled to near absolute zero, these niobium chambers become both highly magnetic and superconducting, which permits researchers to increase the speed of subatomic particles without using increasing amounts of electricity.
