Khoom Description
Silicon hlau hmoov: Silicon feem ntau yog tsim los ntawm carbothermal txo nyob rau hauv hluav taws xob furnaces. Molten silicon feem ntau yog muab tshem tawm los ntawm lub cub hluav taws xob thiab muab pov rau hauv cov chunks loj, piv txwv li hauv cam khwb cia hlau pwm. Ntawm kev siv ntau ntawm silicon, ib qho kev faib ua feem ntau yog siv hauv cov hmoov hmoov. Nyob rau hauv cov ntaub ntawv no, lub silicon thaiv los yog particle yuav tsum tau mechanically tawg thiab ces muab av rau hauv ib tug hlau silicon hmoov nrog ib tug predetermined particle loj thiab qhov yuav tsum tau kev tshuaj ntsuam xyuas muaj pes tsawg leeg. Txawm li cas los xij, txoj kev no muaj ntau qhov tsis zoo. Txij li thaum tus nqi txias nyob rau hauv cov txheej txheem ingot casting ntawm molten silicon yog qhov yuav tsum tau qeeb, cov ntsiab lus alloying ntxiv rau molten silicon thiab cov impurities muaj nyob rau hauv molten silicon nws tus kheej muaj lub zog nyiam rau kev sib cais thaum lub sij hawm ingot casting txheej txheem, thiab cov nplej ntawm cov khoom. silicon kuj yuav coarser.
Vim qhov kev sib cais no thiab coarser thawj cov nplej, cov khoom tsis sib xws yog tau txais thaum lub sij hawm kev sib tsoo thiab sib tsoo ntawm ingot silicon blocks, uas tsis zoo rau ntau siv.Oxides, carbides, nitrides thiab carbon nitrides kuj tsim thaum lub sij hawm ingot casting txheej txheem ntawm silicon. . Cov tshuaj no, txawm tias me me, yog qhov tsis xav tau. Thaum lub sij hawm crushing thiab sib tsoo txheej txheem, cov silicon kuj yuav stained nrog hlau vim qhov hnav thiab tsim kua muag ntawm cov khoom siv crushing thiab sib tsoo. Thaum cov silicon block yog tawg thiab hauv av, qhov tawg ntawm cov silicon hais yuav oxidize, yog li ntawd lub nto ntawm txhua silicon particle nyob rau hauv cov tau metallic silicon hmoov yuav muaj ib tug pliaj oxide txheej. Thaum kawg, cov txheej txheem crushing thiab sib tsoo kuj tsim teeb meem ib puag ncig hauv daim ntawv ntawm lub suab nrov thiab plua plav thiab tsim thermal stress. Yog li ntawd, nws yog ib qho tsim nyog los muab ib txoj hauv kev uas tuaj yeem ua rau cov hmoov hlau silicon tsis tu ncua ncaj qha los ntawm molten silicon ntws tawm ntawm hluav taws xob melting rauv.
