Nyob rau hauv lub realm ntawm kev ua haujlwm hlau thiab kev tsim khoom, kev xaiv ntawm lub luag haujlwm Crucible ua yeeb yam zoo, zoo, ua tau zoo ntawm cov txheej txheem melting. Ntawm cov ntaub ntawv ntau yam,graphite silicon carbide (sic) crucilesSawv tawm rau lawv cov khoom tshwj xeeb, ua rau lawv xaiv qhov kev xaiv uas nyiam tshaj plaws rau cov ntawv thov kom hnyav. Tsab ntawv no rho tawm cov cim tshwj xeeb ntawm graphite piv rau lwm cov ntaub ntawv zoo li graphite, alumina, hais txog lawv cov ntawv thov hauv ntau yam lag luam.
Tshwj Qhia Thermal ruaj khov thiab kub tiv
Graphite sic crucibles ua rau muaj kev cuam tshuam tsis sib haum Thermal ruaj khov thiab muaj peev xwm ntau dua li ntawm kev sib nrug deb li 1600 ° C txog 1650 ° C. Qhov kev ua kom zoo tshaj plaws thaum tshav kub tsis pub rau kom yaj ntawm lub siab-melting xws li tooj liab, thiab cov hlau tab sis kuj ua kom tau ntse tus crucible txoj kev ncaj ncees thiab kev xav tau nyob rau hauv huab cua sov thermal. Nyob rau hauv kev sib piv, cov ntaub ntawv zoo li cov ntshiab graphite thiab alumina muab qis thermal tiv, txwv lawv cov ntawv thov siab rau cov kev siv kub.
Tshuaj lom neeg corrosion tsis kam
Cov tshuaj lom neeg inertness ntawm graphite sic crucibles yog lwm qhov txiaj ntsig tseem ceeb, muab kev cuam tshuam rau kev ua kom xeb ntawm ntau yam tshuaj lom neeg. Cov yeeb yaj kiab no ua kom ntseeg tau tias cov crucible tsis paug rau cov yaj, xws li cov tsev lag luam semiconductor thiab cov solar vaj huam sib luag ntau lawm. Thaum ntshiab graphite crucibles kuj muaj cov tshuaj tsis zoo, lawv yuav tsis ua ib qho zoo nyob rau qee qhov chaw corrosive piv rau graphite sic crucailles.
Siab thermal conductivity rau kev ua tau zoo
Lub siab thermal conductivity ntawm graphite sic cruciLes pab txhawb nqa nrawm thiab muaj kev phom sij tshav kub, tseem ceeb rau kev ua kom muaj zog thiab zoo li cov hlau melting. Qhov no tus cwj pwm tau txo qis zog kev siv hluav taws xob thiab lub sijhawm tau melting, txhim kho cov khoom lag luam tag nrho ntawm cov txheej txheem melting. Ntshiab graphite cruciLes qhia cov kev ua tau zoo no, tab sis graphite sic crucilives sib xyaw ua ke, muab ib qho kev sib tw zoo dua hauv kev thov cov ntawv thov.
Cov ntawv thov hla kev lag luam
Qhov tshwj xeeb ntawm graphite sic crucibles ua rau lawv haum rau ntau cov kev siv ntawm cov ntawv thov dhau cov hlau melting. Hauv kev lag luam semiconduct, lawv txoj kev tiv thaiv kom kub thiab tshuaj lom neeg ua rau lawv zoo tshaj rau kev tsim cov khoom silicon wafers thiab lwm cov ntaub ntawv soob. Lub zog hluav taws xob hluav taws xob lub zog kuj muaj txiaj ntsig los ntawm kev siv cov duab puab sic crucibles nyob rau hauv kev tsim cov khoom muaj ntau silicon rau hnub ci panels. Tsis tas li ntawd, lawv cov kav dej ruaj khov thiab ua tau zoo tau ua cov khoom siv xaiv hauv kev tshawb fawb thiab cov kev siv ua kom zoo dua qub, qhov uas muaj kev ntseeg tau yog qhov tseem ceeb.

Graphite silicon carbide crucailes sawv cev rau txoj kev ua haujlwm tseem ceeb hauv kev kub siab, muab cov txheej txheem siab zoo dua qub, thiab cov txheej txheem loj, thiab cov txheej txheem loj. Lawv cov khoom siv hluav taws xob tsis ruaj khov, tshuaj lom neeg ua kom lawv xaiv cov kev xaiv uas nyiam dua rau ntau yam qauv kev lag luam thiab kev ua haujlwm tshiab hauv kev ua haujlwm ua haujlwm. Raws li kev lag luam txuas ntxiv mus hloov zuj zus, qhov kev thov kom muaj cov ntaub ntawv uas muaj peev xwm tiv thaiv kev ua tau zoo thaum xa cov khoom sib xyaw ntawm qhov chaw ua haujlwm thiab cov ntaub ntawv tshawb fawb niaj hnub.
Qhov no tshawb nrhiav hauv qhov zoo thiab cov ntawv thov ntawm cov toj roob hauv pes ntawm lawv lub luag haujlwm hauv kev txhim kho cov khoom lag luam hauv ntiaj teb no, cov khoom lag luam tshiab.
