Khoom Description
Silicon hlau 2202 muaj li 98% silicon, thiab nyob rau hauv xyoo tas los no, kuj muaj cov khoom nrog 99.99% Si. Qhov seem impurities feem ntau suav nrog hlau (Fe), txhuas (Al) thiab calcium (Ca). Feem ntau yog nyiaj grey los yog tsaus grey, nrog cov xim hlau luster. Hard thiab nkig, siab melting point, zoo kub tsis kam, siab resistivity thiab siab oxidation kuj.
Silicon hlau 2202 feem ntau yog tsim los ntawm txoj kev smelting, uas yog, silica (tsuas yog tsim los ntawm SiO2) thiab carbonaceous reductants (xws li roj av coke thiab charcoal) yog smelted nyob rau hauv submerged arc rauv. Nyob rau hauv cov txheej txheem smelting, silicon raug txo los ntawm ore los ntawm cov tshuaj tiv thaiv ntawm carbonaceous reductant thiab silica los ua nws cov hlau silicon. Txhawm rau txhim kho kev tsim khoom thiab cov khoom lag luam zoo, qee cov thev naus laus zis thiab cov cuab yeej siv yuav raug siv hauv cov cuab yeej siv niaj hnub no, xws li hluav taws xob rauv smelting, refining thiab slagging kom tshem tawm impurities.
Silicon hlau 2202 yog ib qho tseem ceeb raw cov ntaub ntawv los ua silicone. Silicone muaj kev ua haujlwm siab thiab qis qis, tiv thaiv oxidation, huab cua tsis kam, hluav taws xob rwb thaiv tsev thiab lub cev tsis muaj zog, thiab yog siv dav hauv kev lag luam tshuaj, textile, kev tsim kho, hluav taws xob thiab hluav taws xob, kev kho mob thiab kev noj qab haus huv, kev tiv thaiv hauv teb chaws thiab kev lag luam tub rog. Tom qab ua kom huv si, silicon hlau 2202 tuaj yeem siv los npaj cov khoom siv purity semiconductor, xws li polysilicon thiab monocrystalline silicon. Cov ntaub ntawv no yog cov ntaub ntawv tseem ceeb rau cov khoom siv hluav taws xob xws li lub hnub ci hnub ci thiab kev sib xyaw ua ke. Silicon hlau 2202 kuj tseem siv tau los npaj ntau yam alloys, xws li txhuas alloy. Lub zog, hardness thiab hnav tsis kam ntawm cov hlau tuaj yeem txhim kho tau zoo los ntawm kev ntxiv tus nqi ntawm cov xim hlau silicon rau cov hlau. Tsis tas li ntawd, nws yog xim hlau silicon 2202 kuj tuaj yeem siv rau hauv cov ntaub ntawv refractory, tshuaj lom neeg kev lag luam thiab lwm yam kev lag luam. Piv txwv li, nws tuaj yeem siv los ua ib qho ntawm cov khoom siv raw ntawm cov refractories los txhim kho qhov kub thiab txias thiab ruaj khov ntawm refractories; Hauv kev lag luam tshuaj, nws tuaj yeem siv los tsim cov khoom siv silicon xws li silane thiab silicone.
Kev lag luam tus nqi ntawm cov hlau silicon 2202 yog cuam tshuam los ntawm ntau yam, suav nrog cov nqi ntawm cov khoom siv raw, kev siv tshuab ntau lawm, cov khoom siv thiab kev xav tau kev sib raug zoo, thiab lwm yam. Nyob rau hauv xyoo tas los no, nrog rau kev loj hlob sai ntawm kev lag luam thiab kev loj hlob ntawm lub zog tshiab, kev thov rau metallic silicon yog nce thiab kev lag luam zeem muag yog dav. Nyob rau tib lub sijhawm, nrog kev nce qib ntawm kev siv thev naus laus zis thiab kev txhim kho ntawm kev tiv thaiv ib puag ncig, cov txheej txheem tsim khoom ntawm cov hlau silicon yog txhim kho tas li thiab ua kom zoo dua qub los txhim kho cov khoom zoo thiab txo cov nqi tsim khoom.
