Niobyòm Alloy & Metal Founisè

Konsènan metal niobyòm pi (Nb) ak Nyobyòm Alloys

Niobium, ke yo rele tou Columbium, se yon metal briyan gri oswa ajan duktil ki pa sal oswa oksid nan tanperati chanm. Niobyòm reyaji ak oksijèn ak alojèn sèlman lè chofe. Niobyòm se mwens korozyon ki reziste pase Tantal nan tanperati ki wo. Niobyòm pa atake asid nitrique jiska 100 ° C, men agresif atake pa melanj de nitrique ak asid fluoridrik. Cho, konsantre idroklorik, silfirik, ak asid fosfò atak li, men cho, konsantre asid nitrique pa fè sa.

Niobyòm pa afekte nan tanperati chanm nan pifò asid. Li se atake pa solisyon alkalin nan yon sèten mezi nan tout tanperati. Akòz koup transvèsal ki ba li yo pou netwon tèmik, Niobyòm gen aplikasyon nan endistri nikleyè. Niobyòm ka elektrik chofe ak anodize nan yon gran varyete koulè ki fè li trè atire nan endistri a bijou.. Niobyòm ajoute nan fè oswa nikèl pou pwodui alyaj nan espas aeryen an, endistri medikal ak elektwonik.

What are the primary uses of Niobium?

Aplikasyon: 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?

Wi, 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.
