Graphite silicon carbide crucailesyog cov khoom siv sib xyaw ua ke hauv ntau cov ntawv thov muaj kub, suav nrog metallurgy, tshuaj txiag kuaj tshuaj, thiab txheej txheem kev lag luam. Cov crucibles no muaj koob meej rau lawv cov kev tiv thaiv kub tsis kam ua, uas yog qhov tseem ceeb rau kev tswj hwm kev ruaj ntseg thiab ua haujlwm nyob rau hauv huab. Hauv tsab xov xwm no, peb delve mus rau hauv lub ntsiab cai uas tswj hwm cov cua sov nqus muaj peev xwm ntawm graphite silichaw crucailles.
1. Siab thermal muaj peev xwm
Ib qho ntawm thawj cov laj thawj graphite silicon carbide crucos bences nyob rau hauv tshav kub nqus yog lawv muaj kev hnyav thermal. Cov xeeb ceem no tso cai rau lawv kom nrawm nrawm thiab khaws ib qho tseem ceeb ntawm tshav kub. Thaum raug rau qhov kub thiab txias, cov crucibles tsis tsuas yog nqus lub zog los ntawm lawv ib puag ncig tab sis kuj tau khaws cov kub kub rau lub sijhawm ntev. Qhov muaj peev xwm tiv thaiv no thiab tswj cov siab ua rau lawv tsis tseem ceeb hauv kev sim thiab cov txheej txheem uas yuav tsum tau kis kom sov.
2. Tshuaj lom neeg
Ntxiv nrog rau thermal muaj peev xwm, tshuaj lom neeg ntawm graphite silicon carbide cruciBles ua si ib tug pivotal lub luag haujlwm hauv lawv cov kev nqus kub. Thaum cov chaw kub siab, cov kab ke sib xyaw ntawm cov crucible tuaj yeem hnov cov pa oxygen los ua cov pa roj carbon dioxide. Qhov kev tawm tsam no yog nrog los ntawm kev tso tawm lub zog, ua rau lub crucible lub tshav kub nqus. Lub Interlay ntawm cov khoom siv tshuaj lom neeg thiab cov xwm txheej ib puag ncig txhim kho nws lub peev xwm nqus tau kub ua kom cua sov.
3. Adsorption Lub Peev Xwm
Graphite Silicon carbide crucai kuj muaj cov peev xwm adsorption, ua kom lawv nyiam thiab khaws cov dej noo thiab lwm qhov tsis txaus ntawm lawv ib puag ncig. Qhov cuab yeej Adsorption muab txoj hauv kev ntxiv rau kev nqus cua kub, ntxiv txhawb cov crucible lub zog muaj peev xwm.

Cov tshav kub nqus cov tshuab ntawm graphite silica silicar crucailes yog ib txoj kev sib cais ntawm lawv cov khoom siv thiab cov yam ntxwv. Lawv cov khoom muaj peev xwm loj ntawm cov khoom siv hluav taws xob, cov khoom siv adsorption zoo sib sau ua ke pab txhawb rau lawv lub peev xwm ua kom muaj cua sov kom cua sov thiab ua kom muaj kev ruaj khov nyob rau hauv qhov kub thiab txias. Cov cwj pwm no ua graphite silicon carride crucailes ib qho cuab yeej tseem ceeb hauv kev tswj kom kub thiab kev ua tau zoo nyob rau hauv cov txheej txheem uas thov kom nruj kev tswj hwm.
