Niobija sakausējumu un metālu piegādātājs

Par tīru niobija metālu (Nb) un niobija sakausējumi

Niobijs, pazīstams arī kā Kolumbijs, ir spīdīgi pelēks vai sudrabaini kaļamais metāls, kas istabas temperatūrā neaptraipa un neoksidējas. Niobijs reaģē ar skābekli un halogēniem tikai sildot. Niobium ir mazāk izturīgs pret koroziju nekā tantalums augstā temperatūrā. Niobium neuzbrūk slāpekļskābei līdz 100 ° C, bet agresīvi uzbruka slāpekļa un hidrofluorskābju sajaukums. Karsts, koncentrēts hidrohlorisks, sēra, un fosforskābes tam uzbrūk, Bet karsts, koncentrēta slāpekļskābe nav.

NIOBIUM neietekmē istabas temperatūrā ar lielāko daļu skābju. Tam zināmā mērā uzbrūk sārmainie risinājumi visās temperatūrās. Sakarā ar zemu satveršanas šķērsgriezumu termiskajiem neitroniem, Niobium ir pielietots kodolieroodā. Niobium var elektriski sildīt un anodēt ar visdažādākajām krāsām, kas rotaslietu nozarē padara to ļoti pievilcīgu. Niobiju pievieno dzelzs vai niķelim, lai ražotu sakausējumus aviācijā, medicīnas un elektronikas rūpniecībā.

What are the primary uses of Niobium?

Pieteikumi: 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?

Jā, 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.
