Kev npaj cov khoom siv raw: Cov khoom siv tseem ceeb ntawm cov hlau silicon yog silicon dioxide (SiO2) thiab txo cov neeg ua haujlwm siv rau smelting, xws li roj av coke, charcoal, thiab lwm yam. Cov khoom siv raw yuav tsum tau crushed thiab hauv av los txhim kho cov tshuaj tiv thaiv ceev thiab txo cov nyhuv. .
Smelting txo: Tom qab sib tov cov khoom siv raw, muab tso rau hauv lub qhov cub hluav taws kub kub kom txo tau cov smelting. Nyob rau hauv qhov kub thiab txias, tus neeg sawv cev txo cov tshuaj tiv thaiv nrog silicon dioxide los tsim cov hlau silicon thiab qee cov khoom lag luam, xws li carbon monoxide. Cov txheej txheem smelting yuav tsum tswj qhov kub thiab txias, huab cua thiab lub sijhawm tshuaj tiv thaiv kom paub meej cov tshuaj tiv thaiv tiav.
Kev sib cais thiab purification: Tom qab cov khoom smelting txias, nws raug cais thiab purified. Kev siv lub cev feem ntau yog siv, xws li kev sib cais ntawm lub ntiajteb txawj nqus, sib nqus sib nqus, thiab lwm yam, kom cais cov hlau silicon los ntawm cov khoom lag luam. Tom qab ntawd cov txheej txheem tshuaj, xws li pickling, dissolution, thiab lwm yam, yog siv los tshem tawm impurities thiab txhim kho cov purity ntawm hlau silicon.
Refining kho: Txhawm rau txhim kho qhov purity thiab zoo ntawm cov hlau silicon, kev kho kom zoo kuj tseem yuav tsum tau ua. Feem ntau siv refining txoj kev muaj xws li redox txoj kev, electrolysis txoj kev, thiab lwm yam. Los ntawm cov txheej txheem no, impurities nyob rau hauv cov hlau silicon yuav raug tshem tawm thiab nws purity thiab siv lead ua qauv tuaj yeem txhim kho.
Tom qab cov kauj ruam saum toj no, cov hlau silicon uas tau txais tuaj yeem ua tiav rau hauv cov khoom sib txawv thiab cov lus qhia tshwj xeeb. Cov khoom siv feem ntau suav nrog silicon wafers, silicon rods, silicon hmoov, thiab lwm yam, uas yog siv rau hauv electronics, optoelectronics, hnub ci zog thiab lwm yam kev lag luam. Txawm li cas los xij, nws yuav tsum raug sau tseg tias cov txheej txheem ntawm cov hlau silicon yuav txawv nyob ntawm seb cov tuam txhab sib txawv thiab cov khoom yuav tsum tau ua. Cov kauj ruam saum toj no tsuas yog qhia luv luv rau cov txheej txheem dav dav.
