Kev piav qhia
Hlau silicon hmoov yog ib qho tseem ceeb raw khoom nyob rau hauv zus tau tej cov industries xws li semiconductors, solar cells, thiab steelmaking. Cov txheej txheem ntau lawm ntawm cov hmoov hlau silicon muaj ob peb kauj ruam, pib los ntawm kev yuav khoom ntawm raw khoom mus rau qhov kawg ntim ntawm cov khoom.
Raw Material Procurement
Cov khoom tseem ceeb hauv cov hlau silicon hmoov ntau lawm yog silicon hlau. Cov hlau silicon siv hauv cov txheej txheem yog los ntawm ntau qhov chaw thoob ntiaj teb. Txawm li cas los xij, qhov zoo thiab muaj pes tsawg leeg ntawm silicon hlau yog qhov tseem ceeb uas yuav tsum tau xav txog thaum lub sijhawm yuav khoom. Silicon hlau nrog qhov tsawg kawg nkaus ntawm 98 feem pua purity yog nyiam.
Ntxiv nrog rau cov hlau silicon, thee thiab ntoo chips kuj tseem siv los txo cov neeg ua haujlwm thaum lub sijhawm smelting.

Smelting txheej txheem
Cov txheej txheem smelting rau kev tsim cov hlau silicon hmoov feem ntau pib hauv hluav taws xob arc rauv. Cov hlau silicon thiab txo cov neeg ua haujlwm raug thauj mus rau hauv lub cub tawg, thiab lub cub tawg hluav taws xob tau hloov mus. Cov hluav taws xob tam sim no heats lub cub tawg mus txog qhov kub ntawm ib ncig ntawm 2000 degree.
Qhov kub siab nyob rau hauv lub cub tawg ua rau cov hlau silicon thiab txo cov neeg ua haujlwm kom hnov mob, tsim cov oxides volatile. Cov oxides khiav tawm, tawm hauv molten silicon thiab carbon tom qab. Cov pa roj carbon reacts nrog molten silicon los ua silicon carbide.
Tom qab qhov kev txo qis no pib, cov molten silicon thiab silicon carbide tau tso tseg rau hauv qhov cub. Lub silicon carbide, ua denser, tog rau hauv qab ntawm lub cub tawg, thaum silicon ntab mus rau sab saum toj vim nws qis dua.
Tom qab ntawd cov silicon molten raug tshem tawm ntawm lub qhov kais dej thiab sau rau hauv ladles. Cov khoom siv silicone tau txias thiab tawg mus rau hauv chunks siv crushing tshuab.
Milling thiab tshuaj ntsuam
Cov crushed silicon chunks yog ntxiv ua tiav siv pob mills, qhov twg lawv yog milled kom tau qhov yuav tsum tau particle loj. Lub milling kuj pab tshem tawm impurities ntawm silicon. Cov khoom siv milled yog tom qab ntawd tshuaj xyuas siv lub vibrating screen cais qhov sib txawv particle loj.
Purification thiab Ntim
Cov theem kawg hauv cov hlau silicon hmoov ntau lawm suav nrog kev ua kom huv thiab ntim khoom. Cov hmoov hlau silicon feem ntau yog purified los ntawm acid leaching los yog alkali leaching. Cov txheej txheem purification yuav pab tshem tawm cov impurities seem ntawm cov khoom.
Cov hmoov purified hlau silicon yog ces ntim rau hauv hnab, chim, los yog lwm yam ntim, npaj rau kev faib.
Xaus
Hauv kev xaus, hlau silicon hmoov ntau lawm yog txheej txheem nyuaj uas muaj ob peb kauj ruam. Los ntawm cov khoom siv raw khoom mus rau qhov kawg purification thiab ntim, txhua theem yuav tsum tau ua tib zoo saib xyuas kom ntseeg tau cov khoom zoo. Hlau silicon hmoov yog ib qho tseem ceeb raw khoom nyob rau hauv semiconductor, solar cell, thiab steelmaking industries, ua rau nws yog ib qho tseem ceeb cov khoom nyob rau hauv lub ntiaj teb no kev khwv nyiaj txiag.
