Lub ntsiab tivthaiv ntawm silicon hlau hmoov yog crystalline silicon. Thaum xub thawj nws muaj cov duab lumpy thiab cov xim sib luag. Tom qab cov kev ua haujlwm sib tsoo lossis kev sib tsoo, nws yog nyob rau hauv lub xeev powdery thiab feem ntau tsis ua haujlwm.
Feem ntau, sodium hydroxide yog siv los ua cov caticas, thiab cov txheej txheem ntawm cov ntsiab lus silica yog ntau tshaj li 30%, ua rau muaj ntau dua 80%, tseem muaj ntau dua li 80% , uas yog dav siv nyob rau hauv kev lag luam ntawm precision casting, catalyst cov cab kuj, ntawv, textiles thiab lwm yam. Cov txheej txheem rau kev npaj silicon hlau hmoov yog yooj yim thiab lub hauv paus ntsiab lus ntawm kev npaj yog qhov tseeb.
Los ntawm cov dispersion, ib qho nqi ntawm cov nqaij nyoos nrog cov roj cua txias, yog li cov txheej txheem raw rau hauv qhov chaw txias, thiab tom qab ntawd cov txheej txheem cua txias, thiab cov txheej txheem ntau lawm yuav ua rau cov khoom siv hluav taws xob hauv silicon. Txhawm rau kom tau txais kev ua kom huv yog xim hlau silicon, nws yog qhov tsim nyog los ua txoj haujlwm zoo ntawm kev tshem implitities.
Silicon hlau yog ntawm cov kev huv siab thiab muaj kev vam meej lim tiam monolithic silicon. Nws yog tsuas yog siv los ua silicon, uas yog siv nyob rau hauv lub 3c- kev lag luam. Ntxiv nrog rau kev tsim cov high-purity semiconductor cov ntaub ntawv, nws kuj tuaj yeem siv los ua cov tshwj xeeb alloys. Thaum cov khoom yuav khoom, koj yuav tsum xaiv cov chaw tsim khoom xaiv lub chaw tsim khoom. Qhov zoo ntawm cov ntaub ntawv tsim tawm hauv peb lub Hoobkas tau lees. Thov hu rau peb cov lus nug.
