1. Lub npe thiab kev faib tawm
Silicon hlau: Silicon hlau yog lub npe lag luam uas tshwm sim nyob rau nruab nrab -1960s thiab qee zaum hu ua crystalline silicon. Nws lub npe thiab categorization feem ntau yog raws li nws siv thiab silicon cov ntsiab lus, thiab txawm hais tias qee zaum nws yog hu ua industrial silicon, nws feem ntau siv los ua ib qho ntxiv rau cov hlau tsis muaj hlau.
Industrial Silicon: Muaj silicon, tseem hu ua quasi-hlau silicon, kuj yog lub npe lag luam uas tshwm sim nyob rau nruab nrab-1960s. Nws qhov kev faib tawm feem ntau yog raws li cov ntsiab lus ntawm silicon, cov ntsiab lus impurity thiab particle loj. Raws li lub teb chaws tus qauv (GB / T 2881-2014), kev lag luam silicon yog cais rau hauv specifications xws li 5530 #, 4410 #, 4210 #, 3303 #, 2202 # thiab hais txog, raws li qhov sib txawv ntawm silicon cov ntsiab lus thiab cov ntsiab lus ntawm peb lub ntsiab impurities hlau, txhuas thiab calcium.
2. Kev sib xyaw thiab purity
Ob lub ntsiab lus tseem ceeb yog silicon, cov ntsiab lus ntawm txog 98% (hauv xyoo tas los no, cov nyiaj Si 99.99% kuj suav nrog), cov khoom tsis zoo rau hlau, txhuas, calcium thiab lwm yam.
Lub purity yuav tsum tau ntawm industrial silicon feem ntau yog siab dua, vim hais tias nws yog tsuas yog siv nyob rau hauv lub semiconductor thiab electronics kev lag luam nrog siab purity yuav tsum.
3.Siv
Kev lag luam silicon feem ntau yog siv hauv kev lag luam semiconductor thiab hluav taws xob, xws li kev tsim cov khoom siv hluav taws xob, iav purity siab, hnub ci vaj huam sib luag thiab cov khoom siv semiconductor. Tshwj xeeb tshaj yog nrog txoj kev vam meej ntawm kev lag luam semiconductor, kev lag luam thov rau kev lag luam silicon tseem loj hlob.
Txawm hais tias silicon hlau kuj tseem muaj cov silicon purity siab, tab sis nws cov kev xav tau purity tsawg, qhov purity ntawm li 96% tuaj yeem ua tau raws li qhov xav tau ntawm cov ntawv thov feem ntau. Nws yog tsuas yog siv rau smelting thiab synthesizing lwm yam silicon tebchaw, thiab yog dav siv nyob rau hauv cov hlau thiab hlau, foundry, thiab txhuas industries. Tsis tas li ntawd, nws tseem tuaj yeem siv rau hauv kev tsim cov cell photovoltaic, lub teeb vaj huam sib luag thiab tsim cov khoom siv refractory.
