Niobium crucibles yog ua los ntawm niobium metch khoom, uas yog lub ntsej muag grey (2468 degree) thiab qib ntom ntom) thiab qis dua (8.57 g / cm3). Niobium crucibles feem ntau yog puag ncig lossis square nyob rau hauv cov tsos thiab nruab nrog thiab nruab nrog lub hau thiab ceg. Txhawm rau txhawm rau txhim kho kev ruaj khov ntawm cov kub, hauv qab yog feem ntau tsim kom tuab dua. Tsis tas li ntawd, Niobium crucibles tuaj yeem ua rau ntau qhov ntau thiab tsawg thiab cov duab raws li kev siv sib txawv. Niobium crucibles muaj cov kub kub ua kom muaj zog thiab deformation tsis kam, thiab tsis yooj yim yaj los yog deform.
Cov txheej txheem npaj ntawm Niobium crucible feem ntau yog suav nrog stamping, machining, sintering thiab vuam. Stamping yuav tsum xaiv cov khoom zoo niobium phaj los yog niobium ntawv ntau lawm los ntawm cov pwm uas tau txais kom tau txais Niobium crucaile. Machining yog cov machining ncaj ntawm niobium cruciles cruciles kom tau raws li qhov loj me thiab cov cai yuav tsum tau ua. Sintering yog xaiv kom haum Niobium hmoov, nias nws ua kom zoo nkauj tshuab hluav taws xob, thiab tom qab ntawd cov cua sov nyob rau hauv lub tshuab nqus tsev kom tau txais niobium crucible. Tom qab machining, niobium crucibles cruciles ntawm qhov yuav tsum tau loj yog thaum kawg ua. Cov txheej txheem no yog qhov tsim nyog rau kev tsim cov khoom nruab nrab thiab loj niobium crucibles. Thaum kawg, cov phiaj niobium lossis niobium ntawv ci los yog cov ntau thiab tsawg yog dov thiab welded ntawm cov pob qij txha ua ib qho cylindrical puab. Ib lub phaj sib txawv yog welded nyob rau lwm qhov kawg ntawm lub tog raj kheej, thiab thaum kawg saum npoo thiab kev kho vaj tsev thiab muaj kev kho kom zoo yog tau txais txiaj ntsig niobium crucailles. Cov nqi tsim tsim tau ntawm cov txheej txheem no yog tsawg thiab nws yog qhov tsim nyog rau kev lag luam uas tsis muaj qhov yuav tsum ua kom nruj ntawm qhov loj me.
Niobium crucibles ua lub luag haujlwm tseem ceeb hauv lub ntiaj teb tsis tshua muaj zog smelting txheej txheem. Lawv tuaj yeem tiv taus ntau kub thiab tswj tshuaj ruaj khov kom ntseeg tau tias kev nce qib du ntawm cov txheej txheem smelting. Nyob rau hauv lub teb ntawm high-kub sintering, niobium crucibles tuaj yeem siv los ua cov phiaj kub-sintered. Lawv cov kub ua tsis kam thiab deformation tiv taus ua rau lawv xaiv qhov zoo tshaj plaws. Niobium crucibles muaj cov tshuaj zoo heev tiv taus ntau yam tshuaj lom neeg, yog li lawv tuaj yeem siv tshuaj lom neeg-tiv taus ntau yam khoom noj. Nyob rau hauv lub sputtering evaporation cov txheej txheem, Niobium crucibles tuaj yeem tiv thaiv kom ntau kub thiab nyob ruaj khov los xyuas kom meej kev vam meej ntawm sputtering evaporation. Nyob rau yav tom ntej, Niobium crucibles yuav txuas ntxiv mus ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntau dua thiab kev txhim kho ntawm tib neeg lub zej zog.
