siab tensile zog 99.95% Niobium hlau
Niobium hlau yog cov khoom siv siab purity niobium nrog purity ntawm 99.95%, feem ntau hu ua niobium hlau. Cov khoom siv raw rau kev tsim cov niobium hlau yog high-purity niobium, uas yog ua rau filamentous niobium cov ntaub ntawv los ntawm cov txheej txheem yas. Vim nws zoo plasticity ntawm chav tsev kub, niobium tuaj yeem ua deformation xws li dov, kos duab, spinning, thiab khoov yam tsis muaj cua sov.

1. Raw khoom extraction
(Niobium feem ntau yog muab rho tawm los ntawm cov ntxhia pyrochlore)
2. Kev kho kom zoo
(Lub extracted niobium yog ces refined kom tshem tawm impurities thiab tsim ib tug high-purity niobium hlau)
3. Smelting thiab casting
(Lub refined niobium yog melted thiab cam khwb cia rau hauv ingots los yog lwm yam ntaub ntawv haum rau ua ntxiv)
4. Hlau kos duab
(Lub niobium ingots yog tom qab ntawd ua tiav los ntawm cov kab kos duab tuag kom txo tau txoj kab uas hla ntawm cov hlau thiab tsim cov hlau uas xav tau)
5. Ntxoov ntxoo
(Lub niobium hlau yog ces annealed los daws tej kev ntxhov siab thiab txhim kho nws ductility thiab workability)
6. Kev kho deg
(kev ntxuav, txheej, lossis lwm yam txheej txheem los txhim kho nws cov khoom lossis tiv thaiv nws ntawm corrosion)
7. Kev tswj kom zoo
- Superconducting hlau nplaum: Niobium hlau yog siv los tsim cov hlau nplaum superconducting rau kev siv xws li magnetic resonance imaging (MRI) machines, particle accelerators, thiab maglev (magnetic levitation) trains.
- Aerospace: Niobium hlau yog siv nyob rau hauv kev lag luam aerospace rau kev siv xws li aircraft xyaw, roj turbines, thiab foob pob ua ntxaij propulsion systems vim nws kub-siab zog thiab corrosion kuj.
- Cov khoom siv kho mob: Vim nws cov biocompatibility thiab corrosion kuj nyob rau hauv tib neeg lub cev, niobium hlau yog siv nyob rau hauv cov khoom siv kho mob xws li pacemakers, implantable defibrillators thiab lwm yam kev kho mob implants.
- Cov txheej txheem extraction nyuaj: Cov txheej txheem rho tawm thiab kho cov txheej txheem ntawm niobium yog qhov nyuaj thiab xav tau cov cuab yeej tshwj xeeb thiab kev txawj ntse. Qhov no yuav ua rau cov nqi ntau lawm thiab ua rau muaj feem cuam tshuam rau kev lag luam tus nqi ntawm niobium.Cov ntawv thov kev tshaj lij: Niobium muaj nuj nqis rau nws cov khoom tshwj xeeb, xws li superconductivity, corrosion resistance, thiab high-temperature zog. Cov khoom no ua rau nws yog cov khoom siv nrov rau kev siv tshwj xeeb hauv kev lag luam xws li aerospace, kev kho mob thiab hluav taws xob, uas tuaj yeem tsav nws tus nqi.
Niobium yog ib yam khoom uas yog mos thiab du. Nws hardness zoo ib yam li titanium ntshiab thiab muaj ib tug kuj tsawg hardness piv rau ntau lwm yam hlau. Qhov softness thiab ductility no ua rau niobium kuj yooj yim rau txheej txheem, tso cai rau nws los ua ntau yam duab thiab cov qauv kom haum rau ntau yam kev siv.
Niobium yog siv nyob rau hauv steel ntau lawm vim nws ua rau kom lub zog, toughness thiab formability ntawm hlau. Thaum ntxiv rau cov hlau me me, niobium cov ntaub ntawv carbides uas ua kom cov hlau zoo dua qub thiab inhibit grain loj hlob raws li cov hlau txias. Qhov kev hloov kho no tuaj yeem txhim kho cov khoom siv dag zog xws li kev ua kom muaj zog, hardness, thiab tsis kam hnav thiab qaug zog. Tsis tas li ntawd, niobium tuaj yeem txhim kho qhov weldability thiab tshav kub-tshem cov khoom ntawm cov hlau, ua rau nws muaj txiaj ntsig zoo alloying nyob rau hauv ntau yam kev siv steel, nrog rau cov khoom siv tsheb, cov kav dej, cov khoom siv, thiab cov hlau tsis tshua muaj zog (HSLA) steels. .
