Hauv thaj tsam ntawm kev ua haujlwm hlau thiab kev tsim khoom, kev xaiv cov khoom siv crucible plays lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov ua tau zoo, zoo, thiab tus nqi-zoo ntawm cov txheej txheem melting. Ntawm ntau yam ntaub ntawv muaj,graphite silicon carbide (SiC) cruciblessawv tawm rau lawv cov khoom tshwj xeeb, ua rau lawv qhov kev xaiv zoo tshaj plaws rau kev kub kub ntawm cov hlau melting. Kab lus no delves rau hauv qhov tshwj xeeb zoo ntawm graphite SiC crucibles piv rau lwm cov ntaub ntawv xws li ntshiab graphite, alumina, thiab hlau crucibles, qhia txog lawv cov kev siv hauv kev lag luam sib txawv.
Exceptional Thermal Stability thiab Kub Resistance
Graphite SiC crucibles muaj qhov tsis sib xws thermal stability thiab tsis kam mus rau qhov kub thiab txias, muaj peev xwm tiv taus ib puag ncig kub li 1600 ° C txog 1650 ° C. Qhov kev tiv thaiv zoo tshaj plaws no tsis tsuas yog tso cai rau cov melting ntawm high-melting-point hlau xws li tooj liab, kub, nyiaj, thiab hlau tab sis kuj ua kom lub crucible kev ncaj ncees thiab ntev nyob rau hauv huab cua kub tej yam kev mob. Nyob rau hauv sib piv, cov ntaub ntawv xws li ntshiab graphite thiab alumina muaj qis thermal kuj, txwv lawv tsim nyog rau tej yam kev siv kub.
Chemical Corrosion Resistance
Cov tshuaj inertness ntawm graphite SiC crucibles yog ib qho tseem ceeb kom zoo dua, muab resilience tiv thaiv corrosive nres ntawm ntau yam tshuaj koom nrog hauv cov txheej txheem hlau melting. Qhov no ua kom ntseeg tau tias lub crucible tsis paug cov yaj, qhov tseem ceeb rau kev lag luam uas cov hlau purity yog qhov tseem ceeb, xws li hauv kev tsim khoom semiconductor thiab hnub ci vaj huam sib luag. Txawm hais tias cov ntshiab graphite crucibles kuj muaj cov tshuaj tiv thaiv zoo, lawv yuav tsis ua tau zoo hauv qee qhov chaw corrosive piv rau graphite SiC crucibles.
High Thermal Conductivity rau kev ua haujlwm zoo
Lub siab thermal conductivity ntawm graphite SiC crucibles ua kom yooj yim thiab sib xws thaum tshav kub kub faib, tseem ceeb heev rau kev ua tau zoo thiab zoo ib yam hlau melting. Cov cwj pwm no txo qis kev siv hluav taws xob thiab lub sijhawm yaj, txhim kho tag nrho cov khoom tsim tau ntawm cov txheej txheem melting. Ntshiab graphite crucibles qhia qhov txiaj ntsig zoo no, tab sis graphite SiC crucibles ua ke nrog cov thermal stability zoo dua, muab qhov zoo sib xws hauv kev thov.
Daim ntawv thov thoob plaws kev lag luam
Cov khoom tshwj xeeb ntawm graphite SiC crucibles ua rau lawv haum rau ntau yam kev siv tshaj li cov hlau yaj. Hauv kev lag luam semiconductor, lawv tsis kam mus rau qhov kub thiab txias thiab tshuaj lom neeg corrosion ua rau lawv zoo tagnrho rau kev ua silicon wafers thiab lwm yam khoom siv semiconductor. Lub hnub ci hluav taws xob tseem tau txais txiaj ntsig los ntawm kev siv graphite SiC crucibles hauv kev tsim cov roj purity silicon rau hnub ci vaj huam sib luag. Tsis tas li ntawd, lawv cov kav ntev thiab kev ua haujlwm tau ua rau lawv xaiv cov khoom siv hauv kev tshawb fawb thiab kev siv hlau tshwj xeeb, qhov tseeb thiab kev ntseeg siab yog qhov tseem ceeb.
