Silicon hlau (Si Hlau), tseem hu ua crystalline silicon lossis muaj silicon, feem ntau yog siv los ua ib qho ntxiv rau cov hlau tsis muaj hlau. Silicon hlau muaj lub siab melting point, zoo kub tsis kam, siab resistivity thiab superb oxidation kuj. Si Hlau yog cov khoom tsim los ntawm smelting quartz thiab coke nyob rau hauv lub cub hluav taws xob. Lub ntsiab tivthaiv yog silicon, thiab lwm yam impurities yog hlau, txhuas thiab calcium.

• Upstream ntawmCov hlau

Silica ore yog cov khoom siv tseem ceeb tshaj plaws rau kev smelting ntawm silicon hlau, uas feem ntau yog cov ntsiab lus dav dav rau vein quartz, quartzite thiab quartz sandstone. Ntshiab silica tuaj yeem siv rau quartz iav lossis refining monocrystalline silicon. Cov tsos ntawm crystalline silica feem ntau yog creamy dawb, greyish dawb, lub teeb daj thiab reddish xim av. Nws muaj qhov tshwj xeeb lustre, du thiab txuas ntxiv nrog cov npoo ntse, thiab zoo heev hardness thiab lub zog. Vein Quartz yog tuab thaiv, dawb ntshiab, translucent, plaub hau roj ci, plaub hau roj ntau tshaj 2 hli, lub qhov muag liab qab muaj peev xwm pom tau. Quartz xuab zeb feem ntau yog hais txog ntau silica-muaj dej xuab zeb, hiav txwv xuab zeb, weathered xuab zeb, thiab lwm yam, ntxiv rau lub ntsiab ntawm silica, tab sis kuj muaj hlau oxide, av nplaum, mica thiab organic impurities. Quartz xuab zeb, raws li nws tus kheej qib ntawm lub cev ore thiab cov qib ntawm kev ua haujlwm tsis zoo ib yam tuaj yeem muab faib ua quartz xuab zeb, quartz hmoov, ultrafine silica micropowder, square quartz, siab purity quartz thiab lwm yam.

• Hauv qab ntawm silicon hlau

Daim ntawv thov ntawm cov hlau silicon yog dav siv, raws li kev lag luam daim ntawv thov cov khoom tuaj yeem muab faib ua polysilicon, organic silicon thiab alloy silicon; ntawm lawv, polysilicon tuaj yeem raug smelted ntxiv rau hauv monocrystalline silicon. Polysilicon (monocrystalline silicon) feem ntau yog siv rau hauv kev lag luam photovoltaic thiab semiconductor kev lag luam, alloy silicon feem ntau yog siv hauv kev lag luam tsheb tsim; thaum cov organic silicon tas li siv nyob rau hauv kev lag luam ib txwm (cov khoom siv kho mob, cov khoom siv hluav taws xob), tab sis kuj tseem muaj nyob rau hauv kev lag luam tawm tshiab xws li 5G hauv paus chaw nres tsheb.
