kev siv cov hlau silicon
Silicon yog dav siv nyob rau hauv smelting rau hauv ferrosilicon alloys li alloying ntsiab nyob rau hauv cov hlau thiab steel kev lag luam, thiab raws li ib tug txo tus neeg sawv cev nyob rau hauv ntau yam hlau smelting. Silicon kuj yog ib qho zoo tivthaiv hauv aluminium alloys, feem ntauCast aluminium alloy Ob leeg muaj silicon. Silicon yog cov khoom siv raw ntawm ultra-ntshiab silicon hauv kev lag luam hluav taws xob, thiab cov khoom siv hluav taws xob ua los ntawm ultra-ntshiab semiconductor monocrystalline silicon muaj qhov zoo ntawm qhov me me, lub teeb yuag, kev ntseeg tau zoo thiab lub neej ntev. Nws yog tsim los ntawm silicon ib leeg muaju doped nrog cov kab tsis huv tshwj xeebHigh-power transistors, rectifiers thiab hnub ci hlwb, zoo dua li cov uas ua los ntawm germanium ib leeg muaju.
ntau lawm txoj kev ntawm silicon hlau
Nws raug txo los ntawm kev sib xyaw silica nrog Si02 cov ntsiab lus ntawm li 95% thiab coke nrog cov hmoov tshauv tsawg, thiab cua sov kom txog li 1900 degree. Lub purity ntawm silicon npaj los ntawm txoj kev no yog 97% ~ 98%, uas yog hu ua silicon hlau. Tom qab ntawd cov hlau silicon yog melted thiab recrystallized, thiab cov impurities raug tshem tawm nrog acid, thiab purity yog 99. 7% -99. 8% silicon hlau. Yog tias nws yuav tsum tau ua rau hauv silicon rau semiconductors, nws yuav tsum tau hloov mus rau hauv ib qho yooj yim-rau-purify kua los yog roj daim ntawv, thiab ces distilled thiab decomposed kom tau polysilicon, thiab yog hais tias high-purity silicon yog tau, yuav tsum tau purification ntxiv.
