Kev lag luam silicon muaj kev cuam tshuam zoo heev los ntawm kev lag luam tsheb hauv ib cheeb tsam lossis lub tebchaws. Qhov no yog vim tias silicon aluminium alloy, uas yog siv dav hauv kev lag luam aluminium alloy, ua lub luag haujlwm tseem ceeb hauv kev tsim khoom. Raws li lub zog sib xyaw deoxidizer, silicon aluminium alloy hloov cov ntshiab txhuas, yog li txhim kho cov txiaj ntsig ntawm deoxidation thiab txhim kho tag nrho cov hlau zoo hauv steelmaking. Tsis tas li ntawd, cov hlau no muaj peev xwm ua kom huv si molten steel ntxiv txhim kho cov hlau kawg. Qhov kev thov rau kev lag luam silicon, tshwj xeeb tshaj yog rau cov ntawv thov txhuas, tshwj xeeb yog qhov tseem ceeb hauv kev lag luam tsheb thiab ntau lwm cov haujlwm. Qhov no qhia txog qhov cuam tshuam tseem ceeb ntawm kev lag luam tsheb loj hlob ntawm kev hloov pauv ntawm kev lag luam silicon.
Kev lag luam silicon yog ua hauj lwm tsis tsuas yog raws li ib tug additive nyob rau hauv non-ferrous alloys tab sis kuj raws li ib tug alloying neeg sawv cev nyob rau hauv silicon steel, yuav tsum tau nruj specifications. Tsis tas li ntawd, nws yog siv los ua deoxidizer thaum lub sij hawm smelting txheej txheem ntawm cov hlau tshwj xeeb thiab tsis-ferrous alloys.
Silicones ua lub luag haujlwm tseem ceeb hauv kev lag luam tshuaj lom neeg vim lawv siv los tsim ntau yam khoom xws li roj hmab silicone, silicone resin, silicone roj, thiab lwm yam derivatives. Ib daim ntawv thov tseem ceeb ntawm silicone roj hmab yog nyob rau hauv nws qhov tshwj xeeb elasticity thiab muaj peev xwm tiv taus qhov kub thiab txias, uas ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev tsim khoom siv kho mob thiab kub kub gaskets. Ntawm qhov tod tes, silicone resins pom lawv siv nyob rau hauv zus tau tej cov xim insulating thiab kub coatings, ntxiv nqi rau cov kev siv. Lub caij no, cov roj silicone, paub txog nws cov viscosity zoo ib yam tsis hais txog qhov kub thiab txias, pom nws cov khoom siv hauv cov roj nplua nyeem siab, cov neeg ua haujlwm glazing, cov dej ntws, thiab cov kua dej dielectric. Tsis tas li ntawd, nws tuaj yeem hloov pauv mus rau hauv cov kua dej tsis muaj xim thiab pob tshab, txau rau hauv cov chaw ua haujlwm raws li tus neeg sawv cev tiv thaiv dej siab tshaj. Kev paub ntau yam thiab cov khoom ntawm silicones ua rau lawv yog ib feem tseem ceeb ntawm kev lag luam tshuaj, ua haujlwm rau ntau lub hom phiaj thiab siv tau.
Polysilicon thiab monocrystalline silicon, uas yog muab los ntawm kev lag luam silicon tom qab cov txheej txheem purification, ua lub luag haujlwm tseem ceeb hauv kev lag luam photovoltaic thiab kev lag luam hluav taws xob. Cov ntaub ntawv no pom muaj ntau daim ntawv thov nyob rau hauv lub hnub ci lub ru tsev fais fab chaw nres tsheb, chaw nres tsheb fais fab kev lag luam, thiab lub nroog fais fab chaw nres tsheb uas cov nqi av siab. Nrog lawv cov kev loj hlob zoo kawg li, crystalline silicon hlwb tau tshwm sim raws li cov laus tshaj plaws thiab dav siv hnub ci photovoltaic khoom thoob ntiaj teb, ntes ntau dua 80% ntawm lub ntiaj teb ua lag luam. Tsis tas li ntawd, qhov tseem ceeb ntawm high-purity metalloid silicon tsis tuaj yeem raug cuam tshuam vim nws tsim cov caj qaum ntawm niaj hnub loj-teev integrated circuits thiab ua haujlwm tseem ceeb rau cov khoom siv kho qhov muag fiber ntau. Hauv cov ntsiab lus, metalloid silicon tau tsim nws tus kheej ua ib qho tseem ceeb hauv kev lag luam hauv cov ntaub ntawv hnub nyoog.
