3. Synthesis crucible: siv rau kev tsim thiab npaj cov khoom siv siab-purity, xws li cov ntaub ntawv semiconductor, cov ntaub ntawv ceramic, thiab lwm yam.
4. Lub tshuab nqus tsev vacuum: tsim nyog rau kev ua kom sov thiab yaj hauv qhov chaw nqus tsev, feem ntau yog siv rau kev npaj cov ntaub ntawv tshwj xeeb thiab kev smelting ntawm cov hlau purity siab.

Cov khoom siv tsim khoom ntawm graphite crucible muaj kev tiv taus kub thiab tshuaj lom neeg ruaj khov. Nws tuaj yeem siv rau qhov kub siab yam tsis muaj kev hloov pauv lossis kev puas tsuaj vim kub siab. Tib lub sijhawm, graphite crucible kuj muaj kev tiv taus corrosion zoo heev thiab tuaj yeem tiv taus kev yaig ntawm ntau yam tshuaj lom neeg, yog li ua kom ntseeg tau tias qhov zoo ntawm kev tsim khoom ntawm cov khoom siv semiconductor.

Cov ntawv thov tseem ceeb ntawm graphite crucibles hauv semiconductor yog dab tsi?

Hauv cov txheej txheem tsim khoom semiconductor,cov khoom siv graphitefeem ntau yog siv los nqa thiab tiv thaiv cov khoom semiconductor, thiab kuj tuaj yeem hloov pauv cua sov thiab tam sim no tau zoo. Los ntawm lub tes tuav thiab peb lub brackets ruaj khov ntawm qab ntawm graphite crucible, ntau cov khoom semiconductor tuaj yeem muab tso rau hauv graphite crucible kom lawv nyob hauv kev sib cuag zoo nrog graphite crucible, yog li ntawd hloov pauv cua sov thiab tam sim no tau zoo.

Tsis tas li ntawd xwb, graphite crucible kuj siv tau ua ib qho khoom siv hluav taws xob thiab thermal conductive zoo tagnrho. Vim nws muaj thermal conductivity thiab electrical conductivity siab, graphite crucible tuaj yeem coj cua sov thiab tam sim no los ntawm sab nraud ntawm cov khoom siv mus rau cov khoom semiconductor hauv graphite crucible, yog li ua kom cov khoom semiconductor sov thiab tswj tau tam sim no.

Tsis tas li ntawd xwb, graphite crucible kuj tseem tuaj yeem ua haujlwm ua tus neeg coj cua sov thiab hluav taws xob zoo tagnrho, uas tuaj yeem haum rau ntau yam khoom siv semiconductor, uas tso cai rau cov khoom siv los ua ntau yam khoom tib lub sijhawm, yog li txhim kho kev ua haujlwm ntawm cov khoom siv.

Cov kev siv ntawm graphite crucible hauv kev lag luam yog dab tsi?

Qhov ruaj khov kub thiab tshuaj lom neeg ruaj khov ntawm graphite crucible ua rau nws tiv taus cov hlau smelting ntawm qhov kub siab, ua kom ntseeg tau qhov zoo thiab ruaj khov ntawm cov khoom molten. Yog li ntawd, nws tuaj yeem siv los npaj thiab smel ntau yam khoom siv hlau, xws li tooj liab, txhuas, zinc, thiab lwm yam. Tsis tas li ntawd, graphite crucible kuj tseem siv tau los npaj thiab smel cov khoom siv alloy.

Tsis tas li ntawd xwb, cov graphite crucibles kuj muaj kev tiv thaiv corrosion zoo. Graphite muaj kev tiv thaiv corrosion zoo rau feem ntau cov tshuaj lom neeg thiab tuaj yeem tiv taus kev puas tsuaj ntawm cov tshuaj corrosive xws li acids, alkalis, thiab cov kuab tshuaj. Yog li ntawd, graphite crucibles feem ntau siv los khaws cia, tuav, thiab tshuaj xyuas cov tshuaj corrosive. Piv txwv li, hauv kev lag luam tshuaj lom neeg, graphite crucibles tuaj yeem siv rau cov qauv pickling, yaj cov tshuaj, thiab khaws cov tshuaj reagents acidic. Hauv kev tsim cov organic, graphite crucibles tuaj yeem siv rau kev kho cov tshuaj tiv thaiv thiab cov catalysts, nrog rau cov txheej txheem crystallization thiab ziab ntawm cov tshuaj organic.

Kev Sau Ua Ke

Ntxiv rau nws daim ntawv thov hauv kev tsim khoom semiconductor, graphite crucibles kuj tseem tuaj yeem ua lub luag haujlwm tseem ceeb hauv metallurgy, casting, machinery, chemistry thiab lwm yam teb. Piv txwv li, hauv kev lag luam metallurgical, graphite crucibles tuaj yeem siv los yaj thiab kho cov khoom siv hlau; hauv kev lag luam casting, graphite crucibles tuaj yeem siv los yaj cov khoom siv hlau thiab ua ntau yam khoom siv hlau; hauv kev lag luam tshuaj lom neeg, graphite crucibles tuaj yeem siv ua reactors lossis thawv rau cov tshuaj tiv thaiv. Yog li ntawd, tus nqi ntawm graphite crucibles tsis yog tsuas yog cuam tshuam rau nws cov teb thov, tab sis kuj nyob rau hauv nws lub luag haujlwm tseem ceeb hauv kev tsim khoom lag luam. Nrog rau kev txhim kho tas mus li ntawm kev tshawb fawb thiab thev naus laus zis, kev cia siab ntawm daim ntawv thov ntawm graphite crucibles yuav dav dua.
