Nkag mus rau lub ntiaj teb ntawm hlau silicon silicon, peb yuav ua ntej nyiam los ntawm nws cov "dual cwm pwm". Hlau silicon, kev paub txog kev lag luam silicon, yog qhov yooj yim muaj cov khoom siv sib txawv ntawm 98%, thiab 25%, cov ntsiab lus sib luag tsawg dua lossis sib npaug rau 0.02%. Qhov no zoo li yooj yim sib xyaw ntawm cov lej yog qhov tseeb ntawm microcosm ntawm kev kawm zoo ntawm kev lag luam niaj hnub. Tsis zoo li tus paub zoo ib qho Crystal silicon, metallurgical-grade hlau silicon tsis yog muaj kev lag luam zoo, tab sis ntsib tus nqi tsim nyog, xav txog pragmatic muaj kev txawj ntse.
Nyob rau hauv txhuas alloy ntau lawm rhiav, hlau Silicon qhia tau tias nws "khawv koob". Tom qab ntxiv 4% {{-13}}}}}} hlau ntawm aluminium li alloy tau txhim kho, thiab lub zog tseem zoo dua. Tsheb log tsheb, qhov chaw cav thiab txawm tias lub xov tooj ntawm tes, suav cov khoom uas peb tau nkag mus rau hauv cov cuab yeej ntawm cov hlau silicon. Dab tsi yog qhov tseem ceeb tshaj plaws yog tias hlau silicon kuj tseem tuaj yeem tsim cov tshuaj sib xyaw ua ke ntawm cov alloy, uas ua rau nws kuj muaj ib qho chaw hauv lub teb chaws aerospace. Hlau Silicon zoo ib yam li cov tsis paub txhawb txoj haujlwm, tab sis nws txhawb kev ua tau zoo ntawm cov protagonist tom qab. Kev lag luam tshuaj yog lwm theem rau hlau silicon kom tso nws cov txuj ci. Ntawm no, hlau silicon tau hloov mus rau hauv cov khoom siv ntawm silicone. Tom qab cov txheej txheem ntawm cov nyom, hlau silicon yog hloov mus rau cov khoom lag luam silicone xws li cov roj silicone, silicone roj hmab, thiab silicone resin. Cov ntaub ntawv no muaj cov yam ntxwv zoo heev xws li qhov siab thiab kub tsis kam, huab cua tsis kam, thiab rwb thaiv tsev. Los ntawm tus me nyuam pacifiers mus rau spacecraft ntsaws, los ntawm lub tsev waterproofing cov neeg sawv cev rau kev kho mob mindeters, silicone cov khoom tau nkag mus rau txhua lub ces kaum ntawm lub neej niaj hnub no. Thiab tag nrho cov no pib nrog cov hlau inconspicuous hlau silicon thaiv.
Hauv kev lag luam hlau, nws yog xim hlau silicon ua lub luag haujlwm ntawm "scavenger". Raws li deoxidizer, nws tuaj yeem tshem tawm oxygen los ntawm Molten hlau thiab txhim kho qhov zoo ntawm cov hlau; Raws li ib tug neeg sawv cev ua ke, nws tuaj yeem txhim kho cov khoom hluav taws xob thiab kub ua luam ntawm cov hlau. Nws yog tsim nyog tshwj xeeb uas nyob rau hauv kev tsim cov kev tsim khoom silicon tau zoo rau kev txuag hluav taws xob, ua rau muaj kev txuag hluav taws xob thiab emission txo hauv kev lag luam muaj zog. Qhov no zoo li yooj yim kev thov ua tau zoo txhawb kev txhim kho ntawm kev ua haujlwm ntawm lub zog ntawm cov txheej txheem kev lag luam tag nrho.
