Cov khoom tsim tau yog ib daim ntawv ntshiab thiab ua kom zoo ntawm silicon uas muaj ntau yam kev siv thoob plaws ntau yam kev lag luam.
Ib qho tseem ceeb tshaj plaws ntawm kev siv hlau silicon hmoov yog nyob rau hauv kev tsim cov aluminium alloys. Qhov sib ntxiv ntawm cov hlau silicon rau txhuas txhim kho nws cov khoom siv kho tshuab thiab lub cev, ua rau cov alloys ruaj khov, ruaj thiab corrosion-resistant. Qhov no alloy yog dav siv nyob rau hauv automotive, aerospace thiab kev tsim kho kev lag luam.
Lwm qhov kev siv tseem ceeb ntawm kev lag luam silicon yog hauv kev tsim cov hnub ci hlwb. Nws yog ib qho tseem ceeb hauv kev tsim cov cell photovoltaic, uas yog lub luag haujlwm rau hloov lub hnub ci rau hauv hluav taws xob. Nrog rau kev nce ntxiv ntawm lub zog tauj dua tshiab thoob plaws ntiaj teb, kev lag luam silicon tau dhau los ua cov khoom siv tom qab siv zog rau kev hloov pauv ntsuab.
Industrial silicon kuj yog ib qho tseem ceeb muaj nyob rau hauv kev tsim cov khoom siv silicone. Cov khoom no yog siv rau hauv kev tsim cov sealants, adhesives, thiab gaskets rau tsheb, kev tsim kho, thiab hluav taws xob kev lag luam. Tsis tas li ntawd, cov khoom siv no yog siv hauv kev tsim cov xov tooj ntawm tes, cov khoom siv kho mob, thiab lwm yam khoom siv niaj hnub.
Hauv kev lag luam steelmaking, hlau silicon hmoov yog ntxiv rau deoxidizing thiab alloying tus neeg sawv cev hauv kev tsim cov hlau zoo. Nws ntxiv rau cov txheej txheem tshem tawm impurities thiab txhim kho qhov zoo ntawm cov khoom kawg. Cov hlau zoo yog qhov tseem ceeb hauv kev tsim kho thiab kev tsim khoom lag luam.
Hlau silicon hmoov yog cov khoom siv tseem ceeb hauv kev tsim cov hlau ductile, uas yog cov khoom siv tau yooj yim thiab muaj ntau yam khoom siv. Qhov sib ntxiv ntawm silicon hauv cov txheej txheem tsim cov hlau txhim kho nws lub zog, yoog raws thiab tiv thaiv nws cov brittleness.
Nrog rau lub luag haujlwm tseem ceeb uas cov hmoov hlau silicon ua si hauv kev lag luam sib txawv, nws qhov kev thov tseem nce ntxiv. Cov neeg tsim khoom tab tom nrhiav cov hmoov zoo silicon los ntawm cov chaw muag khoom muaj koob npe los xyuas kom meej tias lawv cov khoom muaj cov khoom xav tau thiab ua tau raws li qhov xav tau tshwj xeeb.
Hauv kev xaus, kev lag luam silicon tau dhau los ua cov khoom siv tsis tseem ceeb, ua rau muaj ntau yam kev lag luam. Nws ntxiv rau cov txheej txheem ntau lawm ua rau muaj txiaj ntsig zoo, ua haujlwm zoo, thiab ua haujlwm ntev ntawm cov khoom kawg. Raws li lub ntiaj teb no ua ntau industrialized thiab advanced, qhov kev thov rau hlau silicon hmoov yuav tsuas nce mus ntxiv. Cov khoom lag luam muaj npe nrov ntawm cov hmoov zoo silicon yog qhov tseem ceeb los xyuas kom meej tias kev lag luam muaj kev nkag mus rau cov khoom tseem ceeb no.
