Kev piav qhia ntawm silicon hlau
Silicon hlau feem ntau yog tsim ntawm silicon, yog li nws muaj cov khoom zoo sib xws rau silicon. Muaj ob daim ntawv ntau tshaj li ntawm silicon: amorphous silicon thiab crystalline silicon. Amorphous silicon yog cov hmoov greyish-dub uas yog qhov tseeb kuj tseem yog microcrystalline. Crystalline silicon muaj cov qauv siv leadon muaj cov khoom siv leadoonduct thiab surchet point 410 degree, mohs hardness 7, britleness. Amorphous silicon yog chiv siv zog thiab tuaj yeem hlawv cov pa tawm hauv cov pa. Nws reacts nrog cov tsis muaj hlau xws li Halogen, Nitrogen, thiab Carbon thaum muaj hlau xws li magnesium, calcium, thiab hlau los ua cov silicides. Amorphous silicon yog insoluble nyob rau hauv yuav luag txhua inrorganic acids, suav nrog hydrofluoric acid, tab sis nws yog solubluoric acids ntawm nitric acid thiab hydrofluoric acid. Cov tshuaj lom zem sodium hydroxide tuaj yeem yaj Amorphous silicon thiab tso hydrogen roj. Crystalline silicon yog qhov tsis sib xws, nws tsis sib txuas nrog oxygen, tab sis solublluoric acid thiab concentrated sodium hydroxide daws.
Daim ntawv thov ntawm silicon hlau
1. Nws yog siv rau smelting hlau alloys
Silicon hlau yog ib qho ntawm cov ntaub ntawv tseem ceeb rau kev tsim cov hlau, xws li cov hlau cam khwb cia, thiab lwm yam nyob rau hauv cov txheej txheem smelting, silicon ua raws li deoxidizer thiab txo tus neeg sawv cev, uas tuaj yeem tshem tawm cov oxides thiab lwm yam kev cuam tshuam los ntawm cov hlau thiab txhim kho lub purity thiab zoo ntawm cov hlau.
2. Siv hauv kev tsim cov khoom siv kho qhov muag
Silicon hlau kuj yog ib qho ntawm cov ntaub ntawv tseem ceeb rau kev tsim cov khoom siv kho qhov muag, thiab cov khoom siv silicon yuav tsum tau ua kom nruj rau cov filaments thaum lub sijhawm tsim khoom. Vim tias nws siab heev, qis tsis txaus, zoo ruaj khov thiab lwm yam ntxwv, nws yog dav siv hauv kev sib txuas lus.
3. Siv hauv kev tsim cov khoom hluav taws xob
Silicon hlau kuj muaj ntau cov kev siv hauv kev lag luam hluav taws xob, xws li tsim cov khoom lag luam semiconductors, High fais fab roj thiab lwm yam kev siv hluav taws xob. Vim tias nws txoj kev ua tau zoo, muaj kev ruaj khov, thiab tsis yooj yim kom muaj kev ntxhov siab thiab puas los ntawm lub ntiaj teb sab nraud, nws yog qhov feem ntau ntawm cov tshuab hluav taws xob.
