Dab tsi yog cov khoom siv raw rau kev tsim polysilicon?

Cov khoom siv raw rau kev tsim cov polysilicon feem ntau suav nrog silicon ore, hydrochloric acid, metallurgical qib industrial silicon, hydrogen, hydrogen chloride, muaj silicon hmoov, carbon thiab quartz ore.cov

covSilicon orecov: feem ntau silicon dioxide (SiO2), uas tuaj yeem muab rho tawm los ntawm silicon ores xws li quartz, quartz xuab zeb, thiab wollastonite.covHydrochloric acidcov(los yog cov tshuaj chlorine thiab hydrogen): siv los teb nrog qib metallurgical qib industrial silicon los tsim trichlorosilane.covMetallurgical qib industrial siliconcov: Raws li ib qho ntawm cov khoom siv raw, nws reacts nrog hydrochloric acid ntawm qhov kub thiab txias los tsim trichlorosilane.covHydrogencov: siv los txo trichlorosilane los tsim cov khoom siv high-purity polysilicon rods.covHydrogen chloridecov: reacts nrog industrial silicon hmoov nyob rau hauv ib tug synthesis furnace los tsim trichlorosilane.covIndustrial silicon hmoovcov: quartz ore thiab carbon raug txo kom tsim muaj silicon blocks nyob rau hauv lub hwj chim, uas yog crushed rau hauv industrial silicon hmoov.covCov ntaub ntawv nyoos no tau dhau los ua cov tshuaj tiv thaiv tshuaj thiab cov txheej txheem purification kom thaum kawg tau txais cov ntaub ntawv zoo purity polysilicon. Polysilicon yog cov khoom siv tseem ceeb rau kev tsim ib leeg siv lead ua silicon wafers thiab yog siv dav hauv kev lag luam semiconductor, hnub ci hlwb thiab lwm yam.

polysilicon yog cov khoom siv ncaj qha los ua ib qho siv lead ua silicon. Nws yog cov ntaub ntawv siv hluav taws xob yooj yim rau cov khoom siv semiconductor xws li kev txawj ntse niaj hnub, kev tswj tsis siv neeg, kev ua ntaub ntawv, thiab kev hloov pauv photoelectric. Nws yog hu ua "pob zeb ntawm lub tsev microelectronics."

Lub ntsiab polysilicon cov neeg tsim khoom yog Hemlock Semiconductor, Wacker Chemie, REC, TOKUYAMA, MEMC, Mitsubishi, Sumitomo-Titanium, thiab qee cov neeg tsim khoom me hauv Suav teb. Lub tuam txhab saum toj kawg nkaus tau tsim ntau dua 75% ntawm lub ntiaj teb polysilicon ntau lawm hauv 2006.
