### 1. Daim ntawv thov hauv chemistry
1. ** Cua sov ntawm reactants **
Hauv kev sim tshuaj, graphite crucibles feem ntau yog siv los ua kom sov reactants rau cov tshuaj tiv thaiv. Nws cov thermal conductivity zoo heev thiab kub tsis kam ua rau nws ua haujlwm ruaj khov hauv qhov kub thiab txias yam tsis muaj deformation lossis puas.
2. ** Kev kub ntxhov siab heev **
Qee cov tshuaj tiv thaiv yuav tsum tau kub siab heev. Piv txwv li, thaum tsim cov pa oxygen, potassium superoxide yuav tsum tau ua kom sov siab tshaj 1000°C. Lub graphite crucible tuaj yeem tiv taus qhov kub thiab txias, kom ntseeg tau qhov kev ua tiav ntawm qhov kev sim.
3. ** Corrosion tsis kam **
Nyob rau hauv cov tshuaj tiv thaiv catalyzed los ntawm cov kua qaub los yog cov hauv paus, cov iav zoo tib yam yog yooj yim corroded, tab sis graphite crucibles muaj corrosion kuj zoo thiab muaj peev xwm ua tau cov tshuaj tiv thaiv zoo.
### 2. Daim ntawv thov nyob rau hauv lub tshav pob ntawm metallurgy
1. ** Kub kub melting **
Graphite crucibles yog dav siv nyob rau hauv high-temperature melting thwmsim nyob rau hauv metallurgy teb. Piv txwv li, thaum npaj cov hlau, lawv yuav tsum tau rhuab saum lawv cov ntsiab lus melting. Graphite crucible tuaj yeem ua kom sov ruaj khov thiab tswj tau qhov kub thiab txias.
2. ** Cov khoom sib xyaw **
Hauv qee qhov kev sim metallurgical, cov tshuaj yuav tsum tau ntxiv rau cov hlau molten rau kev sib tov. Lub graphite crucible tsis tsuas yog tswj tau qhov kub thiab txias, tab sis kuj ua kom qhov kev vam meej ntawm cov txheej txheem sib tov.
3. **Kev sim metallurgical tshwj xeeb**
Qee qhov kev sim tshwj xeeb xav tau cov thawv kom ruaj khov ntawm qhov kub thiab txias, thiab graphite crucibles yog qhov kev xaiv zoo tshaj plaws rau cov thawv ntim khoom kub zoo li no.
### 3. Daim ntawv thov hauv hluav taws xob
1. ** Kev Kho Mob Kub Kub **
Thaum tsim khoom siv semiconductor, silicon wafers yuav tsum tau rhuab mus rau qhov kub siab tshaj 1,000°C. Graphite crucible tuaj yeem muab qhov yuav tsum tau muaj qhov kub thiab txias ib puag ncig kom ntseeg tau tias ua tiav cov txheej txheem ua tiav.
2. ** Kub kub sintering **
Txhawm rau txhim kho kev ua haujlwm ntawm cov khoom siv hluav taws xob, kev kub siab sintering yuav tsum tau ua. Graphite crucible tuaj yeem ua haujlwm ruaj khov nyob rau hauv qhov kub thiab txias thiab yog qhov zoo tagnrho sintering thawv.
3. **Kev sim tshwj xeeb hauv hluav taws xob**
Hauv kev sim tshwj xeeb hauv hluav taws xob, qhov kub siab ruaj khov ntawm graphite crucible ua rau nws yog qhov tseem ceeb ntawm kev sim ntim ntim.
###4. Daim ntawv thov nyob rau hauv lub tshav pob ntawm kev sim kub
1. ** Kev kho kub ntawm cov khoom siv **
Thaum npaj cov ntaub ntawv ceramic, cov hmoov ceramic yuav tsum tau rhuab saum qhov kub ntawm sintering. Graphite crucibles ua tau zoo tshwj xeeb thoob plaws hauv cov txheej txheem cua sov thiab kub.
2. ** Txhim kho kev ua tau zoo**
Qee cov ntaub ntawv xav tau kev kho kub kub los txhim kho lawv cov khoom. Piv txwv li, thaum npaj cov pob zeb diamond, cov pa roj carbon qhov yuav tsum tau ua kom sov siab tshaj 3000°C. Lub graphite crucible tuaj yeem ua haujlwm ruaj khov ntawm qhov kub thiab txias, ua kom muaj kev txhim kho ntawm cov khoom siv.
3. ** Cov thawv ntsuas kub siab **
Hauv kev sim kub-kub, graphite crucible yog lub thawv uas tsis muaj qhov tseem ceeb, thiab nws qhov zoo tshaj plaws kub-kub ruaj khov ua kom muaj kev vam meej ntawm qhov kev sim.
Raws li cov cuab yeej sim ua tau zoo hauv ntau qhov chaw, graphite crucible plays lub luag haujlwm tsis tuaj yeem hloov pauv hauv ntau yam kev tshaj lij nrog nws qhov tshwj xeeb zoo. Txawm nyob rau hauv cov tshuaj tiv thaiv, metallurgical smelting, hluav taws xob ua, los yog high-temperature thwmsim, graphite crucibles muab ib tug ruaj khov guarantee rau scientific kev tshawb fawb thiab industrial ntau lawm nrog lawv superior kev kawm.
