Raws li paub zoo, hlau silicon hmoov yog tsim los ntawm kev sib tsoo hlau silicon, yog li peb tuaj yeem hais tias hlau silicon yog ib qho tseem ceeb raw khoom rau hlau silicon hmoov. Hlau silicon, tseem hu ua crystalline silicon los yog muaj silicon, feem ntau yog siv los ua ib qho additive rau non-ferrous alloys. Silicon hlau yog cov khoom tsim los ntawm lub sijhawm yaj thiab coke hauv lub cub hluav taws xob. Cov ntsiab lus tseem ceeb ntawm silicon yog kwv yees li 98%, thiab qhov seem impurities yog hlau, txhuas, calcium, thiab lwm yam. Raws li cov ntsiab lus ntawm hlau, txhuas, thiab calcium hauv hlau silicon, nws tuaj yeem muab faib ua ntau hom sib txawv. Tsis tas li ntawd, hlau silicon kuj muaj ntau yam khoom ntxiv, xws li cov hmoov silicon, sab tawv nqaij silicon, cov tawv nqaij dub silicon, hlau silicon slag, thiab lwm yam Silicon micro hmoov, tseem hu ua silicon hmoov, silicon hmoov, los yog silicon hmoov, yog dav siv. nyob rau hauv refractory thiab qhob kev lag luam. Insoluble nyob rau hauv acids ntawm chav tsev kub, soluble nyob rau hauv alkalis. Silicon hlau muaj cov khoom zoo ib yam li germanium, txhuas, thiab tin, thiab muaj cov khoom siv semiconductor.
Silicon muaj ob hom allotropes, ib qho yog xim av tsaus nti amorphous hmoov, uas ua haujlwm thiab tuaj yeem hlawv hauv huab cua. Lwm hom yog siv lead ua ruaj khov (crystalline silicon) silica, uas feem ntau yog siv rau iav thiab lwm yam khoom siv hauv tsev, thaum zoo silica yog siv rau kev tsim cov alloys, hlau, thiab ib leeg muaju. Silicon hlau yog ib qho kev lag luam purified ntawm silicon. Raws li cov khoom siv hlau hauv kev lag luam steel, nws yog dav siv rau smelting ferrosilicon alloys thiab kuj yog ib qho kev txo tus neeg sawv cev rau smelting ntau yam hlau. Silicon kuj yog ib qho zoo tivthaiv hauv txhuas alloys, thiab feem ntau cam khwb cia txhuas alloys muaj silicon. Silicon yog cov khoom siv raw rau ultrapure silicon hauv kev lag luam hluav taws xob. Cov khoom siv hluav taws xob ua los ntawm ultrapure semiconductor monocrystalline silicon muaj qhov zoo ntawm qhov me me, lub teeb yuag, kev ntseeg tau zoo, thiab kev pab lub neej ntev.
Los ntawm kev qhia txog cov ntaub ntawv saum toj no, peb tau txais qee cov ntaub ntawv hais txog cov hlau nplaum silicon. Txawm li cas los xij, thaum hlau silicon yog hauv av rau hauv cov hmoov, nws dhau los ua hlau silicon hmoov, yog li cov khoom siv ntawm cov hlau silicon hmoov zoo ib yam li cov hlau silicon, tab sis lub cev daim ntawv yog txawv. Nws kuj tseem tuaj yeem hais tias kev nkag siab ntawm cov xim hlau silicon yog sib npaug rau kev nkag siab ntawm cov xim hlau silicon hmoov.
