Kev siv tshuaj muaj xws li:
Silicon hlau yog siv los tsim silicones, hluavtaws silica thiab silanes. Silicone cov khoom xws li surfactants, lubricant, sealants thiab adhesives yog siv nyob rau hauv ntau yam sectors nrog rau kev tsim kho (piv txwv li, nyob rau hauv insulating rubbers), muaj cov txheej txheem (xws li ib tug antifoam neeg sawv cev nyob rau hauv cov roj thiab roj kev lag luam), thiab nyob rau hauv kev tu tus kheej (xws li tshuaj pleev ib ce) thiab thauj (CES, 2016). Silanes yog siv rau hauv iav, ceramic, foundry thiab painting industries (European Commission, 2014; Euroalliages, 2016).
Kev siv txuj ci suav nrog:
Aluminium alloys. Silicon yog yaj nyob rau hauv molten aluminium los txhim kho cov viscosity ntawm cov kua txhuas thiab txhim kho cov khoom siv ntawm txhuas alloys.
Hnub ci hlwb. Ultrahigh- qib purity silicon yog siv los tsim cov hnub ci vaj huam sib luag. Silicon solar cells yog cov hlwb siv ntau tshaj plaws hauv kev lag luam muaj hnub ci vaj huam sib luag.
Electronics. Ultra- qib siab purity silicon yog siv dav hauv cov khoom siv hluav taws xob xws li silicon semiconductors, transistors, printed circuit boards thiab integrated circuits. Semiconductor-qib silicon hlau siv los ua cov tshuab computer chips yog qhov tseem ceeb rau cov cuab yeej siv niaj hnub no.
Lwm daim ntawv thov ntawm silicon hlau muaj xws li tawg, refractories thiab ceramics.
Cov txheej txheem ntau lawm ntawm Si Hlau
Feem ntau ntawm silicon refined txhua xyoo - txog 80 feem pua - yog tsim los ua ferrosilicon rau siv hlau thiab steelmaking. Ferrosilicon tuaj yeem muaj nyob qhov twg ntawm 15 thiab 90 feem pua silicon nyob ntawm qhov yuav tsum tau ua ntawm cov smelter.
Lub alloy ntawm hlau thiab silicon yog tsim los ntawm submerged electric arc rauv los ntawm kev txo smelting. Silica- nplua nuj ore thiab carbon qhov chaw xws li coking thee (metallurgical thee) raug crushed thiab loaded rau hauv lub cub tawg nrog rau cov hlau seem.
Thaum kub tshaj 1900℃(3450℃F), carbon reacts nrog oxygen tam sim no nyob rau hauv cov ore, tsim carbon monoxide gas. Ntxiv cov hlau thiab silicon, lub sijhawm no, tom qab ntawd muab sib xyaw ua molten ferrosilicon, uas tuaj yeem sau los ntawm tapping lub hauv paus ntawm lub cub tawg. Thaum txias thiab tawv, ferrosilicon tuaj yeem raug xa tawm thiab siv ncaj qha rau hauv kev tsim hlau thiab hlau.
Tib txoj kev, tsis suav nrog cov hlau, yog siv los tsim cov qib metallurgical silicon uas ntau dua 99 feem pua ntawm cov ntshiab. Metallurgical silicon kuj tseem siv hauv steel smelting, nrog rau kev tsim cov txhuas cam khwb cia hlau thiab tshuaj silane.
Metallurgical silicon yog cais los ntawm impurity theem ntawm hlau, txhuas, thiab calcium uas muaj nyob rau hauv alloy. Piv txwv li, 553 silicon hlau muaj tsawg dua 0.5 feem pua ntawm cov hlau thiab txhuas, thiab tsawg dua 0.3 feem pua calcium.
