Khoom Description

Hlau silicon hmoov yog cov khoom siv tseem ceeb hauv kev tsim khoom ntawm ntau hom kev lag luam. Nws yog siv rau hauv kev tsim khoom siv hluav taws xob, roj teeb, hnub ci vaj huam sib luag, thiab lwm yam.

Kev ua cov hmoov hlau silicon muaj ntau theem uas hloov cov silicon nyoos rau hauv cov hmoov ua kom zoo uas tuaj yeem siv rau ntau yam kev siv.

Thawj kauj ruam hauv kev ua cov hlau silicon hmoov yog cov khoom siv raw xaiv. Qhov zoo ntawm cov khoom kawg yog nyob ntawm qhov zoo ntawm cov khoom siv raw. Silicon yog lub ntsiab raw khoom siv nyob rau hauv zus tau tej cov hlau silicon hmoov. Cov silicon siv yuav tsum yog siab purity, nyiam dua 99%.

Tom qab xaiv cov khoom siv raw, theem ob yog melting. Silicon yog yaj nyob rau hauv lub cub tawg ntawm qhov kub thiab txias ntawm 1400 degree txog 1500 degree. Lub cub tawg siv rau melting tuaj yeem yog lub cub hluav taws xob lossis lub tshuab hluav taws xob ntau zaus. Lub hom phiaj ntawm melting yog hloov cov silicon nyoos mus rau lub xeev molten.

Qhov thib peb theem yog cov txheej txheem refining. Lub molten silicon los ntawm lub melting rauv yog poured rau hauv ib tug cylindrical ntaus ntawv hu ua crucible. Ib txheej ntawm graphite ua raws li kev sib cais ntawm cov molten silicon thiab cov phab ntsa crucible. Cov txheej txheem refining muaj xws li tshem tawm impurities thiab ntxiv cov ntsiab lus alloy. Gas xws li hydrogen yog txhaj rau hauv molten silicon kom tshem tawm cov hlau impurities.

Qib plaub yog txheej txheem ziab. Cov hmoov refined los ntawm lub crucible yog rhuab kom tshem tawm cov dej noo uas yuav muaj condensed thaum lub sij hawm refining txheej txheem. Cov txheej txheem ziab yuav siv sij hawm qhov chaw nyob rau hauv lub qhov cub kom qhuav qhov twg cov hmoov zoo silicon yog raug rau qhov kub siab ntawm 900 degree mus rau 1000 degree rau ob peb teev.

Qhov thib tsib theem yog cov txheej txheem crushing qhov twg cov hmoov qhuav yog crushed mus rau qhov ntau thiab tsawg uas ua tau raws li kev lag luam specifications. Cov hmoov crushed yog ces sieved cais cov hmoov mus rau hauv sib txawv particle loj.

Cov theem kawg yog cov txheej txheem ntim khoom uas cov hmoov hlau silicon tau ntim rau hauv cov thawv airtight kom tsis txhob muaj kab mob. Lub tshuab nqus tsev tshem tawm cov cua seem hauv lub thawv kom tiv thaiv oxidation ntawm cov hlau silicon hmoov.

Kev ua cov hmoov hlau silicon hmoov yog txheej txheem nyuaj uas yuav tsum muaj kev txawj ua haujlwm thiab kev siv tshuab thev naus laus zis los tsim cov khoom zoo. Los ntawm kev xaiv cov ntaub ntawv raw thiab ua raws li cov txheej txheem ua tau zoo, siab purity hlau silicon hmoov tuaj yeem tsim nrog cov khoom zoo dua qub uas ua tau raws li kev lag luam.

Hlau silicon hmoov muaj ntau yam txiaj ntsig uas ua rau nws nyiam xaiv rau kev siv hauv kev lag luam. Ua ntej, nws yog siv los ua raw khoom hauv kev tsim cov hnub ci vaj huam sib luag. Ntxiv mus, nws cov thermal conductivity yog nyob rau hauv kev thov nyob rau hauv kev tsim cov khoom siv hluav taws xob, nrog rau kev siv cov chips ceev.

Khoom Description

Tsis tas li ntawd, hlau silicon hmoov yog siv nyob rau hauv zus tau tej cov aluminium alloys, carbon fiber-reinforced plastics, thiab lithium-ion roj teeb. Tsis tas li ntawd, hlau silicon hmoov yog ib qho tseem ceeb hauv kev ua cov semiconductors thiab transistors.

Hauv kev xaus, kev ua cov hlau silicon hmoov yog txheej txheem nyuaj uas yuav tsum muaj kev ntsuas tsim nyog los lav cov khoom zoo tshaj plaws. Cov txheej txheem muaj ntau theem uas suav nrog kev xaiv raw khoom, melting, refining, ziab, crushing, sieving, thiab
