Niobium niki no gukoresha niobium?

Ikoreshwa ryaniobiumNka nyongeramusaruro ishingiye ku byuma, ishingiye kuri nikel na zirconium ishingiye kuri superalloys, niobium irashobora kuzamura imbaraga zabo.Mu nganda zikoresha ingufu za kirimbuzi, niobium ikwiriye gukoreshwa nkibikoresho byubaka bya reaktor hamwe n’ibikoresho byometse kuri lisansi ya kirimbuzi, ndetse no kurinda amashyanyarazi n’ibikoresho byubatswe mu nganda z’indege n’ikirere.Ubushobozi bwa Niobium busa nubushobozi bwa tantalum, ariko kubera ubucucike buke bwa niobium, ubushobozi bwa buri gice ni bunini.Niobium titanium, niobium zirconium alloy, niobium tin, niobium aluminium germanium nibindi bikoresho byimbaraga zidasanzwe ntibikoreshwa gusa mu gukwirakwiza amashanyarazi, kubyara amashanyarazi, gukora magneti arenze urugero, no kugenzura imiyoboro ya kirimbuzi, ahubwo binakoreshwa mubikoresho byogenda mu cyogajuru, electronique ibikoresho byo gusunika kumato yihuta cyane, hamwe na gari ya moshi yihuta cyane.Kurwanya aside irwanya niobium iruta iya zirconium, ariko ntabwo ari nziza nka tantalum.Irashobora gukoreshwa nka guhinduranya ubushyuhe, kondenseri, kuyungurura, gukangura, nibindi. Carbide ya Niobium irashobora gukoreshwa wenyine cyangwa ifatanije na karubide ya tungsten na karubide ya molybdenum nkuko impimbano zishyushye zipfa, ibikoresho byo gukata, moteri ya moteri ya turbine, valve, amajipo yumurizo na roketi nozzle.Niobium irimo ibyuma bivangavanze bifite imbaraga nyinshi, ubukana bwiza hamwe no kuzimya ubukonje, kandi bikoreshwa cyane mumiyoboro ya peteroli.Litiyumu niobate kristu imwe ikoreshwa mumashusho ya TV.Imiterere ya niobium niobium nicyuma kidasanzwe cyoroshye kandi gifite ibyuma byijimye, kandi aho gishonga ni 2467. C. Ubucucike ni 8,6 g / cm3.Niobium ifite plastike nziza yubushyuhe buke kandi irashobora gutunganyirizwa mubicuruzwa bitandukanye byarangije igice cyumuvuduko ukonje.Kurwanya ubushyuhe bwinshi, imbaraga nyinshi, kuri 1000. C no hejuru iracyafite imbaraga zihagije, plastike hamwe nubushyuhe bwumuriro.Ububasha bukabije ni bwiza cyane ku bushyuhe buke cyane, nko gukuramo 260. Kurwanya bigera kuri zeru nka C. Kuri 150. Munsi ya C, irwanya ruswa y’imiti no kwangirika kwikirere.Irahagaze neza kuri acide nyinshi hamwe numunyu mubushyuhe bwicyumba, ariko bigashonga muri hydrogène.Filime ihamye ya oxyde ikorwa mugihe cya anodisation.Mu myunyu ngugu, niobium.Filime ihamye ya oxyde ikorwa mugihe cya anodisation.Mu myunyu ngugu, niobium na tantalum bibana.Amabuye y'agaciro arimo niobium na tantalum arimo pyrochlore, niobium-tantalite, limonite, niobium-titanium-itwara rutile, rutile na niobium-tantalate.Amashanyarazi amwe n'amwe yo gushonga amabati nayo ni ibikoresho byingenzi byo gutunganya niobium.Itondekanya ryamabuye ya niobium cyangwa ubutare bwa tantalum bigenwa ahanini nubunini bwa niobium cyangwa tantalum mumabuye y'agaciro.Imiterere ya magnetiki ya Nb-Tn igeze kurwego mpuzamahanga.Ikigo cy’ubushakashatsi cya Baoji cy’ibicuruzwa bidasanzwe bitunganijwe neza byagerageje-gukora imashini yinjizwamo ibintu byinshi-nini ya Nb-Tn ya rukuruzi ya superconducting ifite diameter y'imbere ya mm 23.5 ikoresheje insinga zayo.Ugereranije na magnesi zisanzwe, ubu bwoko bwa magneti bufite ingano ntoya, uburemere bworoshye nimbaraga zikomeye za magneti;Nyuma yo gukora amashanyarazi no gufunga, gutanga amashanyarazi ntibisabwa kugirango bikore igihe kirekire.Dukurikije ikizamini cyakozwe n’abakozi b’ubumenyi n’ikoranabuhanga mu Bushinwa n’Abafaransa muri laboratoire yo mu rwego rwo hejuru y’ikigo cy’ubushakashatsi cy’Ubufaransa, kuri - 286.96 ℃, imbaraga zo mu murima wa rukuruzi zigera kuri 154000 Gauss, kandi imikorere yayo igera ku rwego mpuzamahanga .
