Yuav ua li cas ntshiab yog polysilicon?
Cov kev yuav tsum tau ua rau cov polysilicon tsis tshua muaj siab nyob ntawm nws qhov kev siv kawg:
Lub tshuab hluav taws xob (rau cov semiconductors): Qhov no yog theem siab tshaj plaws, feem ntau yuav tsum tau 99.999999 %9% (9n) lossis siab dua kev coj dawb huv. Impurities yuav tsum raug txo kom tsawg rau ib txhiab (ppb) lossis txawm seem nyob rau ib trillion (Ppt) ntau ntau ntau. Txawm tias cov khoom siv hluav taws xob feeb zoo li Boron, phosphorus, lossis cov hlau tuaj yeem ua rau hluav taws xob roj ntsha li no thiab cov kev ua tau zoo ntawm cov khoom sib xyaw ua ke ntawm lawv. Nruj kev ziab cov txheej txheem (zoo li flashdry) yog qhov tseem ceeb tshaj plaws kom tsis txhob muaj kev tiv thaiv cov oxidation thiab kev paug ua ntej siv lead ua kev loj hlob.
Hnub ci qib (rau photovoltaits): thaum tseem yuav tsis tshua muaj nruj me ntsis dua li hluav taws xob, feem ntau nyob ib puag ncig 99.999% (6n) purity. Kev thev tau rau qee qhov kev tsis txaus siab, tshwj xeeb yog docants uas tuaj yeem muaj txiaj ntsig rau cov hlwb hnub ci (zoo li Boron lossis phosphorus), yog siab dua. Kev nce qib hauv cov thev naus laus zis tau txo tus nqi thiab siv hluav taws xob ntawm lub hnub ci-qib polysilicon thaum tswj cov txaus.
Cov txheej txheem lim dej (piv txwv li, distillation ntawm chlorosilanes, txiav vinestallization / kev txiav txim siab crystalming / advanced tsim los ntawm qhov tsis zoo mgs pub.
