Hlau Silicon

Hlau Silicon

 

 

Hlau silicon yog tsim los ntawm kev txo silica (SiO2) nrog carbonaceous txo cov neeg ua hauj xws li roj av coke, ntxuav thee, los yog charcoal nyob rau hauv ib tug smelting cub. Nws muaj tsawg kawg yog 98.7% silicon. Nws yog ib qho tseem ceeb raw khoom rau kev tsim organosilicon tebchaw thiab polycrystalline silicon, thiab nws kuj yog siv nyob rau hauv zus tau tej cov txhuas alloys rau casting thiab deformation.

 

Raws li Tuam Tshoj Nonferrous Metals Industry Association, Hlau Si nyob qib tsib hauv cov khoom ntim ntawm cov khoom tsis yog hlau, tom qab txhuas, tooj liab, zinc, thiab txhuas. Hauv 2021, Tuam Tshoj cov khoom siv hlau Silicon tau nce mus txog 2.61 lab tons, ua rau nce 24.3% piv rau xyoo dhau los.

Kev tsim cov khoom lag luam silicon tseem ceeb yuav tsum ua kom huv si los ntawm kev txo cov silica hauv cov txheej txheem smelting. Cov neeg tsim khoom sib txawv tuaj yeem sib txawv hauv cov ntsiab lus silicon, qib impurity, thiab qhov loj me ntawm lawv cov khoom siv hlau Si. Hauv Suav teb, cov khoom lag luam silicon raug categorized raws li lub teb chaws tus qauv (GB/T 2881-2014), raws li cov ntsiab lus si thiab cov concentrations loj impurities xws li hlau, txhuas, thiab calcium. Cov khoom no yog dav siv nyob rau hauv alloy formulation, polycrystalline silicon ntau lawm, thiab kev tsim cov organosilicon tebchaw.

Nws feem ntau yog siv rau hauv kev tsim cov organosilicon tebchaw, polycrystalline silicon, thiab aluminium-silicon alloys rau casting. Tuam Tshoj sawv ua tus tsim khoom loj tshaj plaws hauv ntiaj teb thiab cov neeg siv khoom lag luam silicon. Raws li SMM cov ntaub ntawv, nyob rau hauv 2021, ntiaj teb no zus tau tej cov hlau si mus txog 4.08 lab tons, nrog Tuam Tshoj accounting rau kwv yees li 77.1% ntawm 3.17 lab tons (cov ntaub ntawv no muaj xws li 97 silicon thiab recycled silicon, nrog rau cov qauv loj dua li ntawm Tuam Tshoj Nonferrous. Metals Industry Association).

Kev tsim khoom thoob ntiaj teb thiab kev siv cov hlau silicon Lump yog qhov sib npaug ntau. Xyoo 2020, cov neeg siv khoom loj tshaj plaws yog cov khoom siv organosilicon ntawm 39%, ua raws li kev lag luam aluminium alloy ntawm 37%. Polycrystalline silicon nyob qib thib peb ntawm 18%, tab sis nws qhov kev siv tau loj hlob sai, qhia tau tias muaj peev xwm tseem ceeb rau yav tom ntej.

Muab piv rau thoob ntiaj teb, Tuam Tshoj muaj peev xwm loj heev rau kev siv cov khoom siv silicon qis qis. Nws cov qauv kev noj haus zoo ib yam li cov qauv thoob ntiaj teb, nrog rau organosilicon, alloy silicon, thiab polycrystalline silicon accounting rau 37%, 29%, thiab 26% ntawm kev noj nyob rau hauv 2020, feem. Tshwj xeeb tshaj yog nyob rau hauv polycrystalline silicon, Tuam Tshoj txoj kev noj feem ntau ho tshaj lub ntiaj teb no nruab nrab, hais txog Tuam Tshoj lub zog ntiaj teb no pawg nyob rau hauv polycrystalline silicon ntau lawm.
