Aloi ya Niobium & Supplier ya Metal

Kuhusu Pure Niobium Metal (Nb) na Aloi za Niobium

Niobium, pia inajulikana kama Columbium, ni metali inayong'aa ya kijivu au ya fedha ambayo haichafui au kuongeza oksidi kwenye joto la kawaida. Niobium humenyuka pamoja na oksijeni na halojeni inapokanzwa tu. Niobium ni sugu kwa kutu kuliko tantalum kwenye joto la juu. Niobium haishambuliwi na asidi ya nitriki hadi 100 ° C, lakini kushambuliwa kwa ukali na mchanganyiko wa asidi ya nitriki na hidrofloriki. Moto, hidrokloriki iliyokolea, kiberiti, na asidi ya fosforasi huishambulia, lakini moto, asidi ya nitriki iliyokolea haifanyi.

Niobium haiathiriwi na joto la kawaida na asidi nyingi. Inashambuliwa na ufumbuzi wa alkali kwa kiasi fulani kwa joto lolote. Kwa sababu ya sehemu yake ya chini ya kukamata nyutroni za joto, Niobium inatumika katika tasnia ya nyuklia. Niobium inaweza kuwashwa kwa umeme na kutiwa mafuta kwa aina mbalimbali za rangi ambayo huifanya kuvutia sana katika tasnia ya vito.. Niobium huongezwa kwa chuma au nikeli ili kutoa aloi katika anga, viwanda vya matibabu na umeme.

What are the primary uses of Niobium?

Maombi: 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?

Ndio, 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.
