Vapor deposition method yog ib txoj hauv kev uas reacts roj ntawm qhov kub thiab txias los tsim cov hlau silicon.Nws lub hauv paus ntsiab lus tseem ceeb yog ua kom cov pa roj carbon monoxide thiab cov roj silicon ntawm qhov kub thiab txias los tsim cov hlau silicon thiab qee cov roj.Cov kauj ruam tseem ceeb rau kev npaj cov hlau silicon los ntawm vapor deposition yog raws li hauv qab no.
(1) Sib tov hlau roj thiab silicon roj los ua cov tshuaj tiv thaiv roj.
(2) Txhaj cov tshuaj tiv thaiv roj rau hauv lub reactor thiab kub nws mus rau qhov kub thiab txias kom hnov mob los tsim cov hlau nplaum silicon thiab qee cov pa roj.
2.Qhov kev thov ntawm cov xim hlau silicon
Cov khoom siv semiconductor
Raws li ib qho tseem ceeb ntawm cov khoom siv semiconductor, silicon hlau yog dav siv hauv kev lag luam hluav taws xob.Cov khoom siv semiconductor yog lub hauv paus ntawm cov khoom siv hluav taws xob, suav nrog cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab lwm yam, ntawm cov khoom siv semiconductor feem ntau siv.Vim lub cev tshwj xeeb ntawm cov hlau silicon, nws tau dhau los ua cov khoom tseem ceeb rau kev tsim cov khoom siv semiconductor.
Khoom siv hluav taws xob hauv lub xeev
Silicon hlau kuj tau siv dav hauv cov khoom siv hluav taws xob hauv lub xeev.Piv txwv li, hlau silicon tuaj yeem siv los tsim cov hlau silicon teb-zoo transistors, hlau silicon teeb-emitting diodes, hlau silicon diodes, thiab lwm yam.
Casting teb
Raws li cov khoom siv zoo tshaj plaws casting, silicon hlau kuj tseem muaj cov ntawv thov tseem ceeb hauv kev ua haujlwm casting.Kev lag luam Casting yog lub hauv paus ntawm kev lag luam kev lag luam, hlau silicon ua cov khoom siv casting tuaj yeem txhim kho kev ua haujlwm ntawm castings, thiab txhim kho kev tsim khoom.Silicon hlau casting muaj cov yam ntxwv ntawm kev ruaj ntseg, siab zog, siab toughness, siab thermal conductivity, siab hnav tsis kam, thiab lwm yam, thiab yog dav siv nyob rau hauv tsheb, machinery, railway thiab lwm yam teb.
metallurgy
Silicon hlau kuj tau siv dav hauv kev lag luam metallurgy.Silicon hlau yog ib qho tseem ceeb raw khoom rau kev tsim hluav taws xob qib silicon, uas yog dav siv nyob rau hauv photovoltaic hlwb, semiconductor pab kiag li lawm, hnub ci hlwb thiab lwm yam high-tech teb, thiab yog ib qho tseem ceeb ntawm cov khoom tshiab.Ntxiv nrog rau kev ua cov khoom siv raw rau kev tsim hluav taws xob qib silicon, nws yog xim hlau silicon tuaj yeem siv los tsim cov alloys, silicate cementing cov ntaub ntawv, thiab lwm yam.
Raws li qhov tshwm sim, silicon hlau yog cov khoom siv tseem ceeb, uas yog siv dav hauv ntau yam xws li hluav taws xob, casting, metallurgy thiab lwm yam.Nrog rau kev txhim kho txuas ntxiv thiab kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, daim ntawv thov kev cia siab ntawm cov hlau silicon yuav dav dua.
