Raws li ib qho ntxiv rau cov hlau tsis yog hlau, nws yog xim hlau silicon yog siv dav hauv kev lag luam steelmaking. Yog li ntawd, qhov twg yog nws cov khoom siv hlau silicon tshwj xeeb? Dab tsi yog qhov txawv ntawmhlau silicon 553thiab 441? Cia peb kawm ntxiv txog nws hauv qab no.

 

Metallic silicon, tseem hu ua crystalline silicon los yog muaj silicon, feem ntau yog siv los ua ib qho ntxiv rau cov hlau tsis yog hlau. Metallic silicon yog cov khoom smelted los ntawm quartz thiab coke nyob rau hauv lub cub hluav taws xob.

 

Lub ntsiab tivthaivsiliconcov ntsiab lus yog hais txog 98%, thiab cov impurities ntxiv yog hlau, txhuas, calcium, thiab lwm yam.

 

 

 

Nyob rau hauv peb lub teb chaws, metallic silicon feem ntau yog cais raws li cov ntsiab lus ntawm nws peb lub ntsiab impurities: hlau, txhuas, thiab calcium.

Raws li qhov feem pua ​​​​ntawm cov hlau, txhuas, thiab calcium hauv cov hlau silicon, nws yog xim hlau silicon tuaj yeem muab faib ua ntau qib xws li 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, thiab 1101.

Hauv txhua qib, thawj thiab thib ob cov lej sawv cev rau feem pua ​​​​cov ntsiab lus ntawm hlau thiab txhuas, thiab tus lej thib peb thiab tus lej thib plaub sawv cev rau cov ntsiab lus calcium, yog li 553 sawv cev rau cov ntsiab lus ntawm hlau, txhuas thiab calcium hauv cov hlau silicon, uas yog {{1} }.5% thiab 0.5%. %, 0.3%; 441 sawv cev rau cov ntsiab lus ntawm hlau, txhuas thiab calcium nyob rau hauvhlau siliconyog {{0}}.4%, 0.4%, 0.1%

 

 

 

Nws tuaj yeem pom tias qhov sib txawv ntawm 441 thiab 553 yog qhov txawv ntawm purity. Cov ntsiab lus silicon ntawm 553 yog Ntau dua lossis sib npaug rau 98.7%, thaum cov ntsiab lus silicon ntawm 441 yog siab dua lossis sib npaug rau 99.1%. Tshwj xeeb, kev lag luam silicon tau txais los ntawm qhov kub-kub cov tshuaj tiv thaiv ntawm quartz thiab carbon nyob rau hauv lub qhov cub submerged. :SIO2+C=SI+CO2.

Quartz tuaj yeem ua rau tsis zoo lossis tsis zoo, thiab cov pa roj carbon monoxide tuaj yeem ua rau tsis zoo lossis zoo. Qhov sib txawv ntawm cov khoom siv raw no txiav txim siab purity ntawm kev lag luamsilicon.

Los ntawm tus nqi saib, pom tseeb tias qhov zoo dua ntawm cov khoom siv raw, yuav kim dua.
