Mekas Niobium ua qhov chaw raws li xav tau

Niobium txheej txheem ntu yog ntau cov khoom tsis xwm yeem thiab cov qauv zoo li cov khoom siv ntawm 99.99%- {5} Nrog nws cov kev kub siab ua hauj lwm zoo (melting point 2468 degree), muaj zog} kev xaiv tshuab, thiab kev kho mob, ua qhov kev xaiv tseem ceeb los hloov cov ntaub ntawv hlau ua kom zoo nkauj.
Cov khoom ntawm niobium txheej txheem yog muab tau los ntawm cov khoom tshwj xeeb ntawm niobium hlau, thaum ua tiav kev ua haujlwm zoo los ntawm kev ua haujlwm sib txawv.
Zoo siab muaj kub siab tiv taus, muaj peev xwm tswj tau ruaj khov kho lub zog ntawm lub sijhawm 1000 Zoo tshaj plaws corrosion, cov yeeb yaj kiab ntom ntom nti (NB ₂ ₂) tsim nyob rau hauv cov khoom siv hluav taws xob ntau dua li ntawm cov yas uas tsis muaj zog ntxiv tias ntawm cov roj stainless thiab titanium alloys.
Cov ntshiab niobium thiab qee cov niobium alloys muaj cov qauv zoo thiab cov ntaub qhwv, thiab cov kav dej los ntawm cov txheej txheem txias, kub yob, thiab ncab kub, thiab ncab kub, thiab ncab kub, thiab ncab kub, thiab ncab kub, thiab ncab kub, thiab ncab kub, thiab ncab kub, thiab ncab kub, thiab ncab kub, thiab ncab kub, thiab ncab kub, thiab ncab kub, thiab ncab kub, thiab ncab kub, thiab ncab kub, thiab ncab kub, thiab ncab kub Lawv kuj tseem tuaj yeem yog customized cov qauv zoo li qub (xws li crucibles, flanges, thiab txiv ntoo) los ntawm kev txiav, stamping, thiab vuam; Tom qab ua, sab hauv kev ntxhov siab tuaj yeem tshem tawm los ntawm annealing txheej txheem (700-900℃rwb thaiv tsev) kom tsis txhob tawg thaum siv.
Tsawg Neutron Kev Sib Tw Hla ntu (tsuas yog 1.1 Lub Hom Phiaj Zog), uas tuaj yeem txo cov tshuaj tiv thaiv nuclear thiab hloov kho rau Nuclear Kev Lag Luam Kev Lag Luam; Kev ua tau zoo thiab cov khoom lag luam zoo tshaj plaws (qee qhov niobium alloys xws li NB Ti excititing genercondures thiab superconducting khoom siv; Zoo biocompatibility, tsis - kev lom rau tib neeg lub cev, tsis yog tsis haum, thiab tuaj yeem siv rau cov khoom siv kho mob.
Lub ntom ntom ntawm niobium yog 8.57g / cm ³, uas tsuas yog 80% ntawm cov hlau thiab 40% ntawm tungsten. Thaum ua kom muaj zog, nws tuaj yeem txo qhov hnyav tus qauv, tshwj xeeb yog tsim nyog rau lub tshuab kev lag luam aerospace tus thov "kev sib zog + siab lub zog"; Thiab cov coefficient ntawm thermal expansion yog tus nqi qis (7.1 ⁻⁶ /℃{{{{[}
