99.95% Purity Niobium raj polished Niobium yeeb nkab
Niobium raj yog lub raj hlau ua haujlwm siab, feem ntau yog tsim los ntawm niobium (Nb), cov hlau hloov pauv nrog lub siab melting point (2468 ° C) thiab boiling point (4742 ° C), thiab qhov ceev ntawm 8.57g / cm³. Niobium raj feem ntau muaj purity siab, xws li ≥ 99.95% lossis 99.99%, thiab ua raws li cov qauv ASTM B394. Lawv tuaj yeem muab tau rau hauv cov tawv tawv, ib nrab tawv, lossis cov mos mos, nrog kev tiv thaiv corrosion zoo thiab kub tsis kam, thiab siv dav hauv aerospace, electronics, thiab petrochemical industries.

1. Peb lub Hoobkas nyob hauv Luoyang City, Henan Province. Luoyang yog thaj chaw tsim khoom rau tungsten thiab molybdenum mines, yog li peb muaj qhov zoo ntawm qhov zoo thiab tus nqi;
2. Peb lub tuam txhab muaj cov kws tshaj lij nrog ntau tshaj 15 xyoo kev paub, thiab peb muab cov kev daws teeb meem thiab cov lus qhia rau txhua tus neeg siv khoom xav tau.
3. Tag nrho peb cov khoom raug soj ntsuam nruj ua ntej xa tawm.
4. Yog tias koj tau txais cov khoom tsis raug, koj tuaj yeem tiv tauj peb kom them rov qab.
1.Kev xaiv raw khoom
(Cov txheej txheem pib nrog kev xaiv ntawm high purity niobium hlau)
2.Melting thiab Casting
(Cov hlau uas xaiv niobium yog melted nyob rau hauv lub tshuab nqus tsev los yog inert gas ib puag ncig)
3.Kev tsim
(Lub niobium ingot yog tom qab ntawd ua tiav los ntawm ntau txoj kev tsim xws li extrusion lossis rotational perforation los tsim ib lub raj hollow)
4.Kev kho cua sov
5.Kev kho saum npoo
(yuav ua tau kom tshem tawm tej impurities lossis oxides ntawm lub raj)
6.Kev Tswj Xyuas Zoo
7.Kev soj ntsuam zaum kawg thiab kev sim
8.Ntim thiab Shipping
- Superconducting daim ntaub ntawv: Niobium yog dav siv nyob rau hauv zus tau tej cov superconducting cov ntaub ntawv, tshwj xeeb tshaj yog niobium-titanium (Nb-Ti) thiab niobium-tin (Nb3Sn) superconducting xov hlau thiab cables. Cov ntaub ntawv no yog siv rau hauv kev siv xws li magnetic resonance imaging (MRI) machines, particle accelerators thiab magnetic levitation (maglev) trains.
- Aerospace: Niobium raj yog siv nyob rau hauv kev lag luam aerospace rau kev siv xws li aircraft xyaw, roj turbine Cheebtsam, thiab foob pob ua ntxaij propulsion systems vim lawv high-temperature zog thiab corrosion kuj nyob rau hauv hnyav ib puag ncig.
- Kev ua tshuaj lom neeg: Niobium raj yog siv rau hauv kev lag luam tshuaj los tsim cov khoom siv tiv thaiv corrosion, xws li cov khoom siv hluav taws xob, cov hlab ntsha thiab cov kav dej uas siv cov tshuaj corrosive thiab cov txheej txheem kub.
Niobium ntxiv rau steel refines remarkably lub cam khwb cia qauv thiab austenite qauv ntawm steel. Ib qho txaus thiab tseem tsawg kawg nkaus kom muaj nuj nqis ntawm niobium tsim nyog rau refining tswj ntawm austenite - grain nyob rau hauv steel yog 0.03 mus rau 004%. 2. Nrog rau qhov sib ntxiv ntawm niobium, coarsening kub ntawm austenite-grains yuav nce.
Niobium yog ib qho ntawm tsib cov hlau refractory; Qhov no txhais tau hais tias nws yog resistant rau huab cua kub thiab hnav. Nws 4491 ° F (2477 ° C) melting point ua rau cov hlau no thiab nws cov alloys zoo tagnrho rau kev kub siab thiab kub kub.
Niobium tsis hnov mob nrog dej hauv ib txwm muaj. Qhov saum npoo ntawm niobium hlau yog tiv thaiv los ntawm nyias oxide txheej.
