Cov khoom lag luam
Hlau silicon 22 0 2 yog kev siv kev lag luam ib leeg silicon, tseem hu ua crystalline silicon lossis kev lag luam silicon. Nws yog cov khoom smelted nyob rau hauv ib submerged arc rauv los ntawm smelting silica thiab carbonaceous txo tus neeg sawv cev. Lub ntsiab tivthaiv ntawm hlau silicon 22 {{4 4 yog silicon lub caij, thiab nws cov ntsiab lus feem ntau yog siab dua 99. {}}%. Impurities feem ntau suav nrog hlau (fe tsawg dua lossis sib npaug {{8%) thiab calcium (ca tsawg dua lossis sib npaug nrog 0.02%).
Kev ua yeeb yam ib txwm muaj ntawm cov hlau silicon 2202 feem ntau yog smeeb, xws li qhuav nrog tus roj liab, thiab lwm yam) nyob rau hauv ib qho kev faib ua feem, thiab muab tso rau hauv ib qho Hluav taws xob cua sov kom kub siab smelting. Txhawm rau txhim kho kev ua tau zoo thiab txo cov pa phem ib puag ncig, cov txheej txheem ntau lawm tau txhim kho nyob rau hauv xyoo tsis ntev los no. Piv txwv li, kev ua liaj ua teb pov tseg (xws li pob kws kab sib luag, reed stalks, thiab lwm yam) yog siv los txo cov nqi uas txo tus nqi tab sis kuj paub cov peev txheej tab sis kuj paub cov peev txheej. Nyob rau tib lub sijhawm, hom cua sov tau hloov kho kom nce cov smelting kub thiab smelting efficiency.
Hlau silicon 2202 feem ntau yog siv los tsim cov khoom cua engicon, npaj cov khoom siv puricond semiconductor, thiab npaj cov ntaub ntawv tshwj xeeb rau cov hom phiaj tshwj xeeb. Raws li cov khoom siv tseem ceeb rau kev tsim cov polysilicon, polysilicon yog cov khoom tseem ceeb rau cov khoom siv hnub ci. Raws li lub ntiaj teb xav tau rau lub zog txuas ntxiv ntxiv, kev thov ntawm cov hlau silicon hauv cov photovoltaic kev lag luam txuas ntxiv mus nthuav dav. Nws yog siv los tsim cov khoom lag luam silicone xws li Silicone roj hmab, thiab cov roj silicone, uas dav siv hauv kev tsim kho, thiab kev lag luam hauv tsheb. Raws li kev ntxiv, nws tuaj yeem txhim kho kev ua tau zoo ntawm txhuas alloys kom tau raws li cov kev xav tau ntawm cov teb. Nws kuj tseem siv tau los ua Silicon steel los xij, silicon-molybdenum pas dej kub thiab lwm yam metallurgy, kev lag luam roj av, roj av, thiab tshuab kev tsim khoom.
Tuam Tshoj yog lub ntiaj teb loj tshaj plaws ntawm cov hlau silical silicon, nrog txoj haujlwm tseem ceeb hauv ob qho kev tsim khoom thiab tawm. Nrog rau kev nce ntxiv ntawm kev tiv thaiv ib puag ncig thiab kev loj hlob, nrog rau kev lag luam photovoltaic, qhov kev thov rau metallic silicon yuav tsum tau loj hlob ntxiv. Muab cov ntawv thov dav ntawm cov hlau silicon nyob rau hauv ib tug xov tooj ntawm kev lag luam thiab nce kev txhawb nqa thoob ntiaj teb thiab kev lag luam promicon kev lag luam yog muaj kev lag luam. Tshwj xeeb, tsav los ntawm lub photovoltaic kev lag luam, qhov kev thov rau high-purity meters nws yog xim hlau dua li yuav tsum nce ntxiv.
