Dab tsi yog qhov txawv ntawm polysilicon thiab silicon?
"Silicon" catchly hais txog theem nroj tsuag silicon (si), metalloid keeb. PolysiliconYog aDaim Ntawv Tshwj Xeebntawm cov lim dej heev silicon -Polycrrystalline(Ua los ntawm ntau silicon muaju) nrog purity feem ntau ntau dua lossis sib npaug rau 99.999% (9n). Li niaj zaus silicon tuaj yeem yog amorphous (tsis {{} {{{{4} - teev ntau lawm rau hnub ci / semiconductor feedstocks.
Leej twg yog tus tsim loj tshaj plaws ntawm polysilicon?
Phiaj suavYog lub ntiaj teb cov neeg tsim khoom tseem ceeb, cov nyiaj txiag rau ntau tshaj 80% ntawm lub ntiaj teb polysilicon muaj peev xwm (2024 cov ntaub ntawv).
Suav teb cov stems los ntawm cov nqi zog qis, nplai, thiab tsoomfwv txhawb nqa rau lub zog txuas ntxiv.
Tsis tau. Polysilicon yog cov khoom lag luam silicon (si), uas yog aMetalloid(Semimetal) {- Tsis muaj cov hlau tseeb. Nws tsis muaj cov khoom siv tawv me me (piv txwv li, kev ua haujlwm siab, zoo meej hluav taws xob conduction) thiab hloov chaw ua pov thawj semiconducting kev coj cwj pwm.
Puas yog Asmeskas tsim polysilicon?
Yog, tab sis ntawm ib tug ntau me me nplai tshaj Tuam Tshoj. Qhov Tseem Ceeb Asmeskas muaj xws li:
Cov polysilicon yog dab tsi thiab nws ua li cas?
Polysilicon is high-purity (>99.9999%) PolyCrystalline silicon, siv nyob rau hauv lub hnub ci thiab semiconductors. Feem ntau cov qauv ntau lawm yog tusSiemens Txheej Txheem:
Refore Refletsallurgical - Qib qeb nrog hydrogen chloride (HCl) los ua Trichhlorosilane (Sicl₃).
Purify shcl₃ ntawm distillation.
Tso nyiaj ntshiab silicon mus rau nyias rods (noob muaju) hauv kev siv tshuaj vapor deposition (CVD) reactor siv hydrogen gas.
Cov txheej txheem tshiab zoo li tusFluidized Txaj Reactor (FBR)Tau txais kev nce qib rau kev siv hluav taws xob tsawg dua.
Cov polysilicon yog dab tsi thiab nws siv rau dab tsi?
PolysiliconYog qhov siab - purity, polycrystalline daim ntawv ntawm kev ua si thaj silicon (si). Nws lub ntsiab siv yog:
Hnub ci photovoltaics (PV): ~ 80% ntawm thoob ntiaj teb tau-}} siv los ua kom cov roj av silicon (hloov lub hnub ci rau hluav taws xob).
Sicultonductors: Higher-purity grades (>11N) yog siv los tsim cov Silicon Wafers rau lub computer chips, sensors, thiab circuated sib xyaw.
Cov nyiaj me me tseem mus rau hauv cov ntaub ntawv siab (piv txwv li, silicon carbide rau EVS).
