Silicon hlau, cov khoom siv tseem ceeb hauv kev lag luam, ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw. Kev tsim cov hlau silicon muaj ntau txoj hauv kev.
Cov khoom siv tseem ceeb rau kev tsim cov hlau silicon yog quartzite. Quartzite yog ib qho nyuaj, crystalline pob zeb tsim los ntawm silica. Cov quartzite no yog crushed thiab hauv av rau hauv cov hmoov zoo.
Tom ntej no, cov hmoov quartzite yog tov nrog carbonaceous cov ntaub ntawv xws li thee los yog coke. Cov ntsiab lus ntawm silicon nyob rau hauv lub ntsiab tivthaiv yog hais txog 98% (xws li 99.99% Si kuj muaj nyob rau hauv hlau silicon), thiab lwm yam impurities yog hlau, txhuas, calcium, thiab lwm yam.Qhov sib tov no ces loaded rau hauv hluav taws xob arc furnaces. Nyob rau hauv cov furnaces, kub heev yog generated los ntawm hluav taws xob arcs. Cov cua kub hnyav ua rau muaj tshuaj lom neeg ntawm cov silica hauv quartzite thiab cov pa roj carbon monoxide los ntawm cov ntaub ntawv carbonaceous.
Cov tshuaj tiv thaiv ua rau txo qis ntawm silica rau silicon. Cov khoom siv silicon yog nyob rau hauv lub xeev molten. Raws li cov txheej txheem txuas ntxiv, impurities raug cais tawm ntawm silicon molten. Cov kauj ruam ua kom huv no yog qhov tseem ceeb kom tau txais cov hlau zoo silicon.
Kev tsim cov hlau silicon yuav tsum muaj kev tswj xyuas nruj ntawm qhov kub thiab txias, cov khoom siv raw zoo, thiab cov xwm txheej ntawm lub cub tawg. Cov kws tshaj lij thiab cov thev naus laus zis thev naus laus zis yog qhov tseem ceeb los xyuas kom meej cov txheej txheem tsim khoom zoo thiab cov khoom tsim tau zoo.
Silicon hlau yog dav siv nyob rau hauv zus tau tej cov txhuas alloys, raws li ib tug deoxidizer nyob rau hauv steelmaking, thiab nyob rau hauv electronics kev lag luam rau kev tsim khoom ntawm semiconductors. Nws cov khoom tshwj xeeb thiab versatility ua rau nws yog ib qho khoom tseem ceeb hauv ntau daim ntawv thov kev lag luam.
