Nijobju Liga & Fornitur tal-metall

Dwar Metall Nijobju Pur (Nb) u Nijobju Ligi

Niobju, magħrufa wkoll bħala Columbium, huwa metall duttili griż tleqq jew fidda li ma jtebbax jew jossidizza f'temperatura tal-kamra. Nijobju jirreaġixxi ma 'ossiġnu u aloġeni biss meta msaħħna. In-Niobju huwa inqas reżistenti għall-korrużjoni mit-tantalu f'temperatura għolja. In-nijobju mhux attakkat mill-aċidu nitriku sa 100 ° C, imma aggressivament attakkat minn taħlita ta 'aċidi nitriċi u idrofluworiċi. Jaħraq, idrokloriku kkonċentrat, sulfuriku, u l-aċidi fosforiċi jattakkawha, imma jaħraq, l-aċidu nitriku konċentrat le.

Niobium mhuwiex affettwat f'temperatura tal-kamra mill-biċċa l-kbira ta 'l-aċidi. Huwa attakkat minn soluzzjonijiet alkalini sa ċertu punt fit-temperaturi kollha. Minħabba s-sezzjoni trasversali tal-qbid baxx tagħha għan-newtroni termali, In-Niobju għandu applikazzjoni fl-industrija nukleari. Niobium jista 'jissaħħan bl-elettriku u jiġi anodizzat għal varjetà wiesgħa ta' kuluri li jagħmilha attraenti ħafna fl-industrija tal-ġojjellerija. Nijobju huwa miżjud mal-ħadid jew nikil biex jipproduċu ligi fl-ajruspazju, industriji mediċi u elettroniċi.

What are the primary uses of Niobium?

Applikazzjonijiet: 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?

Iva, 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.
