Yuav ua li cas los tsim niobium crucibles?

Niobium crucible yog qhov siab - Cov thawv kub ua los ntawm high- Kev Purinal) los ntawm kev lees paub siab, stamping, vuam thiab lwm yam kev ua. Nrog Niobium hlau zoo dua rau 99.95%, nws yog cov khoom siv tseem ceeb hauv kev ua tshuab, cov ntaub ntawv kev kawm thiab lwm thaj chaw vim nws cov khoom siv lub cev thiab tshuaj lom neeg zoo. Nws cov tsos feem ntau nthuav tawm nyiaj grey xim hlau luster, nrog tus qauv ntom thiab cov qauv coj ua. Nws tuaj yeem kho tau nyob rau hauv ntau cov lus qhia tshwj xeeb xws li puag ncig, uas tuaj yeem ntsib cov xwm txheej sib txawv xws li kev kuaj sim sib txawv xws li kev sim thiab kev lag luam kev lag luam thiab kev lag luam ntau lawm.
Lub ntsiab lus melting ntawm Niobium yog siab npaum li 2468 degree, deb tshaj qhov feem ntau hlau thiab alloys. Qhov no tso cai rau Niobium crucibles los tswj cov qauv ruaj khov thiab tuaj yeem siv rau hauv cov pa nqus dej lossis cov roj nyob hauv qab 1600℃rau lub sijhawm ntev. Nyob rau hauv lub sij hawm luv luv, qhov kub muaj peev xwm txawm tshaj 2000 degree. Piv rau ib txwm muaj - tiv taus qhov chaw nyab xeeb, tsis muaj teeb meem, thiab lwm yam teeb meem ntawm kev sim siab thiab kev sim siab. Lawv yog qhov tshwj xeeb rau siab rau high- Cov kev lag luam kub xws li urgractory hlau smelting thiab siab- kub ally npaj.
Nyob rau hauv chav tsev kub thiab nruab nrab tsawg kub thiab muab cov pa roj oxygen tsis zoo xws li cov kua roj dog ua kom zoo li cov duab hluav taws xob thiab cov pa roj ntsha Nyob rau tib lub sijhawm, Niobium cov khoom pov thawj corrosion zoo heev rau ntau cov kua txiv, zinc, thiab lwm yam. Nws yog ib lub thawv zoo tshaj plaws rau kev npaj siab - cov ntaub ntawv huv.
Niobium muaj cov thermal thiab hluav taws xob conductivity, thiab nws thermal conductivity tshwj xeeb yog tshwj xeeb thaum muaj kub. Thaum siv niobium crucible rau cua sov, tshav kub tuaj yeem ua kom sai thiab txo cov pa dej khov kho thiab txo cov ntaub ntawv ntawm kev sim lossis cov khoom ruaj khov ntawm cov khoom lag luam zoo. Tsis tas li ntawd, txoj kev ua zoo tseem tso cai rau Niobium crucible hloov rau ntau txoj kev cua sov xws li cov khoom cua kub, txhim kho cov versatility ntawm cov khoom siv.
