niobium sawb niobium ntawv ci rau Sintering rauv
Niobium sawb yog cov khoom siv hlau nrog siab purity (≥ 99.95%), thiab nws cov yam ntxwv tseem ceeb muaj xws li kub tsis kam thiab corrosion kuj. Qhov ceev ntawm niobium sawb yog 8.57g / cm³, thiab nws melting point yog siab li 2468 ℃. Cov yam ntxwv no ua rau nws siv dav hauv kev lag luam xws li chemistry, electronics, aviation, thiab aerospace. Cov specifications ntawm niobium strips muaj ntau haiv neeg, nrog thickness xws li los ntawm 0.01mm mus rau 30mm thiab dav mus txog 600mm, uas yuav customized raws li tej kev xav tau. Cov txheej txheem ntau lawm ntawm niobium sawb feem ntau suav nrog dov, uas ua kom lub purity thiab kev ua tau zoo ntawm niobium sawb.

Molybdenum lub hom phiaj feem ntau yog siv hauv X-ray raj rau kev kuaj mob, tshuaj xyuas kev lag luam, thiab kev tshawb fawb tshawb fawb. Cov ntawv thov rau cov hom phiaj molybdenum yog feem ntau hauv kev tsim hluav taws xob X-rays rau kev kuaj pom, xws li suav tomography (CT) scans thiab radiography.
Molybdenum lub hom phiaj yog nyiam rau lawv qhov siab melting point, uas tso cai rau lawv tiv taus qhov kub thiab txias tsim thaum lub sij hawm X-ray ntau lawm. Lawv kuj muaj thermal conductivity zoo, pab kom dissipate tshav kub thiab ntev lub neej ntawm X-ray raj.
Ntxiv nrog rau kev kuaj pom kev kho mob, cov hom phiaj molybdenum yog siv rau kev sim tsis muaj kev puas tsuaj hauv kev lag luam, xws li tshuaj xyuas cov vuam, cov kav dej thiab cov khoom siv hauv aerospace. Lawv kuj tau siv rau hauv cov chaw tshawb fawb uas siv X-ray fluorescence (XRF) spectroscopy rau kev txheeb xyuas cov khoom siv thiab kev txheeb xyuas lub ntsiab lus.
Lub sintering kub ntawm niobium tuaj yeem sib txawv nyob ntawm daim ntawv thov tshwj xeeb thiab cov khoom ua tiav. Feem ntau, niobium muaj qhov kub ntawm qhov kub ntawm 2,468 degrees Celsius (4,474 degrees Fahrenheit). Txawm li cas los xij, niobium-based cov ntaub ntawv tuaj yeem sintered ntawm qhov kub thiab txias hauv qab lub melting point, uas feem ntau yog nyob ntawm 1,300 txog 1,500 degrees Celsius (2,372 txog 2,732 degrees Fahrenheit) rau feem ntau sintering txheej txheem. Nws yog tsim nyog sau cia tias qhov tseeb sintering kub ntawm niobium-raws li cov ntaub ntawv nyob ntawm seb muaj pes tsawg leeg thiab sintering txheej txheem yuav tsum tau.
Lub thickness ntau ntawm niobium ntawv ci yog nyob nruab nrab ntawm 0.01mm thiab 30mm, qhia tias niobium strips tuaj yeem kho nrog cov thicknesses sib txawv raws li kev siv tshwj xeeb. Tsis tas li ntawd, muaj lwm qhov ntau thiab tsawg ntawm cov ntawv niobium thiab strips muaj rau kev xaiv, qhia tias ntxiv rau cov tuab, lwm qhov loj me xws li qhov dav ntawm niobium sawb kuj tuaj yeem hloov kho raws li xav tau.
Niobium tsis yog sib nqus ntawm chav tsev kub. Nws raug suav hais tias yog cov khoom siv paramagnetic, txhais tau tias nws tsis khaws cov khoom sib nqus thaum lub chaw sib nqus sab nraud raug tshem tawm. Txawm li cas los xij, niobium tuaj yeem dhau los ua cov hlau nplaum tsis muaj zog thaum raug kub hnyiab los yog alloyed nrog lwm cov ntsiab lus. Niobium hauv nws daim ntawv ntshiab feem ntau yog siv tsis yog rau nws cov khoom sib nqus tab sis rau nws cov kev tiv thaiv zoo rau qhov kub thiab txias, ua rau nws muaj txiaj ntsig hauv ntau yam kev lag luam thiab kev tshawb fawb.
