Raws li cov cuab yeej sim tseem ceeb, cov pa hluav taws xob ntxaij yog cov khoom siv hluav taws xob zoo li cov kab ke, thiab siv hluav taws xob ntau, thiab cov cua sov ua kom zoo. Kab lus no yuav qhia tau cov ntsiab lus tshwj xeeb ntawm kev siv ntawm silicon carbide crucible hauv cov teb no.
### 1. Daim ntawv thov hauv thaj chaw ntawm Chemistry
1. ** Cua sov ntawm Reactanes **
Hauv kev sim tshuaj, teeb tsa cov crucibles feem ntau siv rau cua sov reactants rau tshuaj lom neeg cov tshuaj tiv thaiv. Nws zoo heev thermal conductivity thiab kub ua kom ua kom nws ua haujlwm ruaj khov ib puag ncig muaj kev kub siab lossis kev puas tsuaj.
2. ** KUB HEEV KUB SIAB KUB HEEV **
Qee yam kev tawm tsam yuav tsum tau kub heev. Piv txwv li, thaum ua pa tawm, poov tshuaj Superoxide yuav tsum tau rhuab rau saum toj 1000°C. Cov duab ci ci clucible tuaj yeem tiv taus cov kev kawm kub li qub, ua kom muaj kev vam meej du ntawm kev sim.
3. ** Corrosion Kuj **
Hauv kev tawm tsam catalyzed los ntawm cov muaj zog acids lossis hauv paus, dog dig corroded, tab sis graphite crucas muaj zoo corrosion tau zoo thiab tuaj yeem nyab xeeb ua cov kev tawm tsam no.
### 2. Daim ntawv thov nyob rau tom teb ntawm metallurgy
1. ** High Kub Melting **
Graphite cross yog dav siv nyob rau hauv qhov siab-sim sim kev sim hauv daim teb metallurgical. Piv txwv li, thaum npaj cov hlau, lawv yuav tsum tau muab rhaub saum toj saum lawv cov lus taw. Graphite Crucible tuaj yeem ua kom kub stably thiab tswj hwm qhov xav tau kub.
2. ** Cov khoom sib xyaw **
Hauv qee qhov kev sim metallurgical, cov khoom yuav tsum tau ntxiv rau cov hlau molten rau kev sib xyaw. Tus graphite crucible tsis tsuas yog tswj qhov kub thiab tab sis kuj ua kom tiav kev txhim kho ntawm cov txheej txheem sib xyaw.
3. ** Kev sim tshwj xeeb metallurgical tshwj xeeb **
Qee qhov kev sim tshwj xeeb xav tau cov thawv kom nyob ruaj khov nyob rau ntawm qhov chaw siab, thiab graphbles yog qhov kev xaiv zoo tshaj plaws rau cov chaw khov kho kub.
### 3. Daim ntawv thov hauv daim teb hluav taws xob
1. ** Kev kho kom sov siab **
Thaum tsim semiconductor cov cuab yeej, silaon wafers yuav tsum tau ua kom sov kom kub siab dua 1,000°C. Graphite Crucible tuaj yeem muab qhov uas yuav tsum tau kub ib puag ncig kom ntseeg tau tias cov txheej txheem ua tiav.
2. ** RINTERINGE kub siab rau **
Txhawm rau txhim kho kev ua tau zoo ntawm cov hluav taws xob sib xyaw, kev siv hluav taws xob siab yog qhov yuav tsum tau ua. Graphite Crucible tuaj yeem ua haujlwm ruaj khov raws li cov kev mob siab thiab yog qhov zoo tshaj plaws sintering thawv.
3. ** Kev sim hluav taws xob tshwj xeeb rau kev sim **
Hauv kev sim hluav taws xob tshwj xeeb, qhov kub ntawm cov teeb meem kub ntawm graphite crucible ua rau nws lub thawv tsis tseem ceeb.
###4Cov. Cov ntawv thov hauv cov kev sim kub siab tshaj plaws
1. ** Kev kho kom sov ntawm cov ntaub ntawv **
Thaum npaj cov ntaub ntawv ceramic, cov hmoov av hmoov yuav tsum tau rhaub cov sintering kub. Graphite crucles ua rau tshwj xeeb zoo thoob plaws hauv kev kho cua sov thiab kub thiab kub.
2. ** Kev ua tau zoo dua **
Qee cov ntaub ntawv xav tau kev kho kub siab kom txhim kho lawv cov khoom. Piv txwv li, thaum npaj pob zeb diamond, cov pa hluav taws xob yuav tsum tau ua kom sov siab rau saum toj 3000°C. Daim duab kab ntoo khaub lig crucible tuaj yeem ua haujlwm ruaj khov ntawm xws li kub siab, ua kom cov kev txhim kho ntawm cov khoom ua haujlwm.
3. ** KUB CUA KUAJ THEM THEM **
Hauv kev sim siab, graphite crucible yog ib lub thawv tsis tseem ceeb, thiab nws zoo heev-kub ruaj khov ua kom tiav qhov kev kawm du.
Raws li kev sim sim ua ntau thaj teb, graphite crucible plays ib liaj rau ntau tus kws tshaj lij kev ua haujlwm nrog nws cov txiaj ntsig tshwj xeeb. Txawm hais tias nyob rau hauv cov tshuaj lom neeg cov tshuaj tiv thaiv, metallurgical smelting, kev sim tshuab hluav taws xob tau muab kev lees paub rau kev tshawb fawb thiab kev lag luam muaj nrog lawv kev ua haujlwm zoo dua.
