Cov ncauj lus kom ntxaws ntawm Silicon Hlau

Silicon hlau, tseem hu ua silicon lossis crystalline silicon lossis crystalline silicon, yog lub siab-huv siicon cov ntaub ntawv uas yog kho kom zoo nkauj los ntawm silica los ntawm kev sib tw ntawm cov tshuaj lom neeg. Nws txawv ntawm dab tsi feem ntau hu ua monocrystalline silicon lossis polycrystalline silicon thiab feem ntau yog siv nyob rau hauv cov kev lag luam solid thiab semiconductor kev lag luam. Silicon hlau ua lub luag haujlwm tseem ceeb hauv ntau thaj chaw muaj kev lag luam vim nws cov kev coj ua siab zoo, kev ua haujlwm hluav taws xob zoo thiab corrosion tsis kam.

Cov yam ntxwv ntawm Silicon Hlau

Ntawm qhov kub tsawg tsawg, cov khoom lag luam silican yog tsis ua haujlwm thiab tsis hnov mob nrog huab cua, dej, thiab kua qaub. Nyob rau hauv chav tsev kub, saum npoo yog oxidized los ua ib tug 1000 picometer silica tiv thaiv zaj duab xis tiv thaiv. Thaum muaj kub kub, nws tuaj yeem hnov mob nrog txhua lub halogens los ua silicon tetrahalide, thiab thaum oxygen yog saum 700 degree, nws tuaj yeem hlawv los ua silicon dioxide. Nws reacts nrog hydrogen chloride ntawm 500 degree kom tsim trichlorosilane sihcl3 thiab hydrogen. Thaum kub siab, nws tuaj yeem hnov mob nrog qee cov hlau (magnesium, calcium, hlau, platinum, thiab lwm yam) los ua silicides. Thaum liab-kub, nws dhau los nrog dej vapor los ua silica thiab hydrogen. Nws reacts nrog lub zog alkali daws los tsim cov khoom silicate thiab tso hydrogen. Nws reacts nrog hydrofluoric acid los ua cov silicon tetraflluide.

Cov txheej txheem npaj ntawm silicon hlau

Qhov kev npaj ntawm silicon hlau feem ntau yuav cuam tshuam txog kev tawm tsam ntawm silica (lub ntsiab tivthaiv yog silica) nrog cov carbon ntawm cov ntsuas kub. Tus txheej txheem no yuav tsum tau tswj qhov kub thiab txias nruj heev, lub siab, thiab cov kev xav tau los ua kom muaj kev coj dawb huv thiab qhov zoo ntawm cov khoom kawg. Cov npaj silicon hlau kuj yuav tsum tau ua kom zoo ntxiv thiab ua tiav kom tau raws li cov kev xav tau ntawm kev lag luam sib txawv.

Hauv cov ntsiab lus, silicon hlau ua yeeb yam piv lub luag haujlwm nyob rau hauv kev lag luam niaj hnub vim nws cov kev siv. Nkag siab txog cov khoom siv thiab kev npaj ntawm cov thawv silicon yuav pab peb ua tau zoo siv cov khoom tseem ceeb no thiab txhawb nqa kev txhim kho kev lag luam ntsig txog kev lag luam.
