Lub cev thiab tshuaj lom neeg ntawm silicon hlau
Muaj Kev Ncaj Ncees Siab thiab Crystal: Silicon yog ib semi - tus neeg saib xyuas cov khoom uas muaj qib siab purity. Nws muaj cov qauv crystalline uas ua rau nws cov khoom hluav taws xob thiab cov cua sov no. Hauv nws daim ntawv ntshiab, nws yog qhov tsaus ntuj - grey, lus bar.
Hluav Taws Xob Kev Tshaj Tawm: Txawm hais tias silicon yog semiconductor, metallurgical silicon qhia cov hluav taws xob nruab nrab ntawm hluav taws xob. Cov cuab yeej no tuaj yeem hloov kho tau los ntawm kev ntxiv cov impurities, uas paub txog kev siv cov hluav taws xob hluav taws xob xws li cov trantors thiab dodes.
Thermal ruaj khov: Nws ua pov thawj zoo heev thermal ruaj khov, muaj peev xwm tiv thaiv ntau yam tsis muaj kev cuam tshuam tseem ceeb ntawm nws lub cev lub cev. Qhov no ua rau nws muaj cov khoom siv zoo rau cov ntawv thov hauv cov chaw siab - qhov chaw kub.
Cov txheej txheem ntau lawm ntawm silicon hlau
Kev tsim cov hlau me ntawm cov pob zeb silicon feem ntau tsuas yog qhov txo ntawm silica (sitio₂), feem ntau yog los ntawm quartzite lossis xuab zeb, hauv ib qho hluav taws xob tshuab hluav taws xob. Cov txheej txheem siv cov pa roj carbon - raws li txo cov neeg sawv cev zoo li cov thee, coke, lossis cov ntaub ntoo ntoo. Tshuaj lom neeg tshuaj lom neeg tuaj yeem hais tau yooj yim li: sio₂ {1}} C + 2 co ↑. Thaum lub sijhawm cov txheej txheem no, tej yam kev mob siab, feem ntau nyob ib ncig {4}} degree, yuav tsum tsav cov tshuaj tiv thaiv rau pem hauv ntej. Tom qab thawj zaug smelting, cov pob zeb uas muaj roj ntau ntxiv los tshem tawm cov impurities xws li hlau, thiab calcium, uas tuaj yeem cuam tshuam nws cov kev ua tau zoo hauv cov ntawv thov hauv qab.
