Txoj kev npaj: silicon hlau yog smelted los ntawm quartz thiab coke nyob rau hauv lub cub hluav taws xob. Thaum lub sij hawm smelting txheej txheem, silicon dioxide nyob rau hauv lub quartz yog txo mus rau silicon thiab reacts nrog cov pa roj carbon caij nyob rau hauv lub coke los tsim by-products xws li silicon. hlau thiab carbon monoxide.
2. Lub cev muaj zog
Cov tsos: silicon hlau feem ntau tshwm raws li ib tug tsaus grey los yog xiav-toned siv lead ua nrog ib tug kuj du nto.
Ceev: Qhov ntom ntawm silicon hlau yog 2.34g/cm³.
Melting point: Lub melting point ntawm silicon hlau yog 1420℃.
Conductivity: Lub conductivity ntawm siliconhlauyog ze ze rau nws qhov kub thiab txias. Raws li qhov kub thiab txias, cov conductivity nce, ncav cuag qhov siab tshaj plaws ntawm ib ncig ntawm 1480°C, thiab tom qab ntawd txo qis thaum kub siab tshaj 1600°C.
3. Cov khoom siv tshuaj
Cov khoom siv semiconductor: siliconhlauNws muaj cov khoom siv semiconductor thiab yog ib qho tseem ceeb ntawm cov khoom siv semiconductor.
Cov yam ntxwv ntawm cov tshuaj tiv thaiv: ntawm chav tsev kub, siliconhlauyog insoluble nyob rau hauv acid, tab sis yooj yim soluble nyob rau hauv alkali.
4. Daim ntawv thov teb
Kev lag luam semiconductor: silicon meta yog siv dav hauv kev lag luam semiconductor thiab yog cov khoom siv tseem ceeb rau kev tsim hluav taws xob sib txuas, hnub ci vaj huam sib luag, LEDs thiab lwm yam khoom siv hluav taws xob. Nws cov purity siab thiab cov khoom hluav taws xob zoo ua rau nws yog ib qho tseem ceeb ntawm cov khoom siv semiconductor.
Kev lag luam metallurgical: Hauv kev lag luam metallurgical, metallic silicon yog ib qho tseem ceeb ntawm cov khoom siv raw khoom. Nws tuaj yeem muab ntxiv rau cov hlau los txhim kho qhov nyuaj, lub zog thiab hnav tsis kam ntawm cov hlau thiab txhim kho nws lub cev thiab tshuaj lom neeg. Nyob rau tib lub sijhawm, nws yog xim hlau silicon kuj yog ib qho khoom siv zoo hauv aluminium alloys, thiab feem ntau cam khwb cia aluminium alloys muaj silicon.
Kev lag luam Foundry: Hlau silicon tuaj yeem siv los ua cov khoom siv casting los txhim kho toughness thiab thermal qaug zog tiv thaiv ntawm castings thiab txo qhov tsis xws luag thiab deformation.
Hnub ci hluav taws xob hluav taws xob tsim hluav taws xob: Nws yog xim hlau silicon kuj tseem siv rau hauv hnub ci thermal zog tsim. Los ntawm tsom lub hnub ci zog rau saum npoo ntawm cov xim hlau silicon, lub teeb lub zog tuaj yeem hloov mus rau hauv lub zog hluav taws xob, thiab tom qab ntawd cov hluav taws xob hluav taws xob yog siv los ua kom muaj zog los tsav turbine generators los tsim hluav taws xob.
Lwm yam kev lag luam: Tsis tas li ntawd, nws kuj tseem siv tau los tsim cov khoom siv silicone xws li roj silicone, roj hmab silicone, silane coupling tus neeg sawv cev, thiab rau kev tsim cov khoom siv photovoltaic xws li polycrystalline silicon. Tib lub sijhawm, cov hmoov hlau silicon kuj tau siv dav hauv cov ntaub ntawv refractory, hmoov metallurgy kev lag luam thiab lwm yam kev lag luam.
5. Kev Ua Lag Luam thiab Kev Lag Luam
Kev lag luam xav tau: Nrog rau kev loj hlob ntawm kev lag luam thoob ntiaj teb thiab kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, qhov kev thov rau hlau silicon tseem nce ntxiv. Tshwj xeeb tshaj yog nyob rau hauv kev lag luam semiconductor, metallurgical kev lag luam thiab hnub ci zog teb, kev lag luam thov rau hlau silicon qhia tau hais tias muaj zog loj hlob sai.
Txoj kev loj hlob zoo: yav tom ntej, cov khoom siv hlau silicon yuav txhim kho nyob rau hauv cov kev taw qhia ntawm purity siab dua, cov nplai loj dua thiab cov nqi qis dua. Nyob rau tib lub sijhawm, nrog rau kev loj hlob sai ntawm kev lag luam hluav taws xob tshiab, daim ntawv thov ntawm cov hlau silicon hauv cov khoom siv photovoltaic kuj tseem yuav nthuav dav ntxiv.
Hauv cov ntsiab lus, raws li ib qho tseem ceeb ntawm cov khoom siv raw khoom, hlau silicon muaj cov ntawv thov dav dav hauv ntau qhov chaw. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev nce hauv kev lag luam xav tau, cov khoom siv hlau silicon yuav txuas ntxiv txhim kho thiab tsim kho tshiab, ua kom muaj txiaj ntsig zoo rau kev txhim kho tib neeg lub neej.
