Cov khoom lag luam
Taug kev mus rau hauv ib lub nroog niaj hnub no, cov iav ntaub npog lub ntsej muag, nrog nws cov khoom sib xyaw ua ke, nrog cov khoom siv sib txawv ntawm cov khoom lag luam me me ": cov khoom siv hlau tshwj xeeb"
Lub npe ntawm Silicon hlau 553 los ntawm nws cov qauv tshuaj nruj sib xyaw: "55" txhais tau tias cov ntsiab lus Silicon tsis pub tshaj 0. 3%. Qhov no zoo li yooj yim sib xyaw ntawm cov naj npawb yog qhov tseeb ib tus lej zoo ua tib zoo tsim los ntawm cov cuab yeej siv metallurgical. Piv nrog ntau dua Purity silicon hlau, qauv 553 tau ua tiav qhov sib npaug zoo sib xws ntawm tus nqi thiab kev ua tau zoo, los ua "tus nqi-kev ua tau zoo huab tais" nyob rau ntau daim teb.
Hauv daim teb ntawm txhuas alloy raug, hlau silicon 553 plays ib lub luag haujlwm tseem ceeb. Thaum silicon ntxiv rau txhuas, nws tuaj yeem txhim kho fluidity ntawm alloy, ua rau nws yooj yim dua rau qhov casting sau txhua lub ces kaum ntawm cov pwm. Txawm tias ntau dua qhov ua ke yog tias kev sib xyaw ua ke ntawm silicon thiab aluminium ua rau tshwj xeeb "Eutectic nyhuv", uas muab cov khoom siv zoo li kev ua tau zoo thiab lub zog kho tshuab. Los ntawm cov cav tsheb thaiv kom thaiv rau cov chaw nres nkoj, suav tsis muaj ntau cov khoom siv los ntawm cov nyhuv zoo sib xws. Qhov kev txhim kho booming ntawm silicone kev lag luam tau thawb cov hlau silicon 553 rau theem tshiab ntawm daim ntawv thov. Los ntawm cov tshuaj lom neeg nyuaj, nyuaj silica yog hloov mus rau cov khoom siv Silicone Silicone Nws yog tsim nyog tshwj xeeb uas nyob rau hauv lub hnub ci photheoltaic, hlau sidicon 553, raws li cov khoom siv sib luag ntawm cov txiaj ntsig hloov dua siab tshiab thiab cov nqi tsim khoom ntawm lub hnub ci. Raws li kev txheeb cais, txog 65% ntawm lub ntiaj teb cov hlau silicon thaum kawg ntws mus rau cov khoom lag luam silicone thiab photovoltaic, ua ib qho kev tsav tsheb tseem ceeb rau lub zog ntsuab lub zog.
Kev npaj ntawm hlau silicon 553 yog ib qho kev txhais tau zoo ntawm qhov kub-alchemy. Nyob rau hauv ib lub tshuab hluav taws xob ua hluav taws xob nyob rau ntawm 2 {000 degree, (quartz dioxide yog txo kom ua kua silicon. Lub zog siv hluav taws xob ntawm cov txheej txheem no yog qhov xav tsis thoob. Nws yuav siv sijhawm li 12, 000-14}, 000 degrees ntawm hluav taws xob los tsim 1 tuj ntawm cov hlau silicon, uas yog sib npaug rau kev siv hluav taws xob siv hluav taws xob txhua xyoo. Yog li no, lub ntiaj teb hlau silicon ntau lawm yog feem ntau muaj nyob rau hauv cov chaw muaj hluav taws xob nplua nuj, xws li lwm qhov chaw, sib sau ib qho qauv muaj kev lag luam tshwj xeeb.
