1. Hlau kev lag luam
Kwv yees li 85 feem pua -90 feem pua ntawm lub ntiaj teb no niobium yog siv nyob rau hauv steel ntau lawm nyob rau hauv daim ntawv ntawm ferroniobium. Tsuas yog ntxiv 0.03 feem pua -0.05 feem pua niobium rau cov hlau tuaj yeem ua rau cov hlau tawm los ntawm ntau dua 30 feem pua. Ntxiv niobium rau steel tsis tsuas yog ua kom lub zog ntawm cov hlau, tab sis kuj txhim kho lub toughness, kub oxidation tsis kam thiab corrosion kuj ntawm cov hlau, txo cov nkig hloov kub ntawm cov hlau, thiab ua rau cov hlau muaj zoo vuam kev kawm thiab formability. .
2. Superconducting khoom kev lag luam
Qee cov tebchaw thiab cov alloys ntawm niobium muaj qhov kub hloov pauv hloov pauv siab, yog li lawv tau siv dav hauv kev tsim khoom ntawm ntau yam kev lag luam superconductors, xws li superconducting generators, accelerator high-power magnets, superconducting magnetic zog cia khoom, nuclear magnetic resonance imaging khoom, thiab lwm yam. .. Tam sim no, cov ntaub ntawv tseem ceeb tshaj plaws yog niobium-titanium thiab niobium-tin, uas tau siv dav hauv cov khoom siv magnetic resonance imaging instruments rau kev kuaj mob thiab nuclear magnetic resonance instruments rau spectral kab (kev tshuaj xyuas).
3. Kev lag luam hluav taws xob
Niobium muaj lub siab melting point, muaj zog muaj peev xwm emit electrons, thiab muaj peev xwm kom tau roj, yog li nws yuav siv tau los ua electron raj thiab lwm yam hluav taws xob nqus tsev. Ntxiv mus, niobium tebchaw muaj piezoelectric zoo, pyroelectric thiab optical zog, thiab tuaj yeem siv dav hauv infrared, laser technology thiab hluav taws xob industries.
4. Nuclear zog kev lag luam
Niobium muaj cov thermal conductivity zoo, siab melting point, zoo corrosion kuj, thiab tsawg neutron capture cross-section. Nws yog cov khoom siv zoo heev rau atomic zog reactors. Nws feem ntau yog siv los ua cov khoom siv hluav taws xob hluav taws xob, cov khoom siv hluav taws xob nuclear, thiab kev sib pauv cua sov hauv nuclear reactors. Cov khoom siv ntawm cov khoom siv.
5. Aerospace kev lag luam
Kev lag luam aerospace yog qhov tseem ceeb ntawm daim ntawv thov kev lag luam ntawm high-purity niobium, uas yog tsuas yog siv nyob rau hauv zus tau tej cov cav thiab kub-resistant qhov chaw ntawm foob pob ua ntxaij thiab spacecraft. Thaum tshav kub kub-lub zog alloys ntawm niobium thiab tantalum muaj zoo tshav kub lub zog, tshav kub tsis kam thiab ua cov khoom, thiab feem ntau yog siv los tsim ib feem ntawm aero-engines thiab hniav ntawm cov roj turbines.
6. Kev kho mob teb
Niobium muaj qhov zoo ntawm lub cev tiv thaiv corrosion thiab biocompatibility, yuav tsis cuam tshuam nrog ntau yam kua hauv tib neeg lub cev, thiab yuav tsis ua rau cov ntaub so ntswg puas tsuaj, yog li nws feem ntau siv los tsim cov pob txha daim hlau thiab pob txha taub hau phaj screws, kho hniav, cov cuab yeej phais, thiab lwm yam.
7. Lwm yam kev siv
Hauv kev lag luam tshuaj, niobium yog cov khoom siv zoo uas tiv taus cov kua qaub thiab kua hlau corrosion, thiab tuaj yeem siv los ua cov tshuab digesters, cua sov, cua txias, thiab lwm yam. Niobium pab ua kom lub teeb kis tau zoo ntawm lub lens, yog li nws kuj yog siv hauv kev tsim cov lo ntsiab muag hauv kev lag luam kho qhov muag. Hauv kev lag luam tsheb tsim, ferroniobium tuaj yeem siv los ua cov khoom siv lub cev muaj zog, lub tog raj kheej taub hau thiab lub nplhaib piston ntawm lub tsheb, thiab lwm yam.
