Qhov yuav tsum tau ua ntawm Silicon rau Kev Lag Luam Tshuaj

Cov hlau silicon ua nyob rau hauv Suav teb (nrog cov ntsiab lus silicon feem ntau 98.5 feem pua) yog thawj zaug siv rau metallurgical lub hom phiaj, thaum tsim cov tshuaj hlau silicon (nrog cov ntsiab lus silicon feem ntau 99.85 feem pua) tau tsim los txij li nruab nrab {{4. }}s. Kev tsim thiab xa tawm cov tshuaj silicon hauv Suav teb tau loj hlob sai. Los ntawm 1999 mus rau 2001, Tuam Tshoj tus export ntawm tshuaj silicon rau Nyiv tau mus txog 22000 tons, 30000 tons thiab 40000 tons raws li. Nyob rau hauv 2001, Tuam Tshoj tus export ntawm tshuaj silicon rau Nyiv accounted rau ntau tshaj 40 feem pua ​​ntawm Nyiv cov tshuaj silicon ntshuam. Tuam Tshoj tau pib koom nrog cov qib ntawm cov tshuaj silicon ntau lawm thiab muab lub teb chaws, nrog rau cov tuam txhab tsim cov tshuaj silicon ntau zuj zus. Vim muaj kev nthuav qhia ntawm cov pa roj carbon thermal txo smelting txheej txheem los ntawm Shanghai Guangji Silicon Materials Co., Ltd. nyob rau hauv 2002, Tuam Tshoj lub peev xwm ntau lawm ntawm hlau silicon sai li sai tau los ntawm 100000 tons ib xyoo mus rau 1.2 lab tons ntawm 2002 thiab 2004. , Lub Koom Haum Saib Xyuas Kev Txhim Kho Hauv Lub Tebchaws thiab Kev Txhim Kho Kev Ua Haujlwm tau tsim cov kev rau txim loj, thiab hauv 2006, qhov tseeb ntawm cov hlau silicon poob rov qab rau 700000 tons. Nyob rau xyoo 2006, tsuas yog Shanghai Guangji Silicon Materials Co., Ltd. Dawu Silicon Factory tau ua tiav 10000 tuj hlau silicon Hoobkas, Jingxin Hoobkas, nyob rau hauv ciam teb ntawm Xinjiang. Lwm cov chaw tsim khoom silicon tau tsim. Chemical silicon hais txog cov xim hlau silicon siv hauv kev tsim cov organic silicon thiab polycrystalline silicon. Los ntawm kev xav thoob ntiaj teb, kev siv cov khoom siv hlau ua silicon ntau dua li cov tshuaj silicon. Txawm li cas los xij, nrog kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis, kev siv tshuaj silicon hauv kev tsim cov organic silicon thiab semiconductors txuas ntxiv nthuav dav, thiab tau siv dav hauv kev tsim cov organic silicon monomers thiab polymer silicone roj, silicone roj hmab, silicone resin tsev. anti-corrosion, waterproofing agents, thiab lwm yam. Lawv muaj cov yam ntxwv tshwj xeeb xws li kub tsis kam, hluav taws xob rwb thaiv tsev, hluav taws xob tiv thaiv, thiab waterproofing. Siv nyob rau hauv hluav taws xob, aviation, mechanical, chemical, pharmaceutical, lub teb chaws tiv thaiv, kev tsim kho thiab lwm yam departments. Raws li cov khoom siv hluav taws xob tseem ceeb ntawm kev sib koom ua ke, ntau dua 95 feem pua ​​​​yog ua los ntawm semiconductor silicon, uas yog lub hauv paus ntawm cov ntaub ntawv kev lag luam niaj hnub no. Optical fiber ntau hauv optical fiber cable, uas yog dav siv nyob rau hauv "Information superhighway", kuj yog tsim nrog hlau silicon raws li raw khoom. Kev noj cov tshuaj silicon hauv Tebchaws Meskas thiab European Union tso nyiaj ntau dua ib nrab ntawm tag nrho cov khoom siv hlau silicon. Cov tshuaj silicon tau siv dav hauv kev lag luam high-tech thiab kev lag luam tseem ceeb, thiab nws cov kev siv tau nce mus rau kev loj hlob ruaj khov. Raws li kev lag luam thoob ntiaj teb ib txwm muaj, tus nqi muag ntawm cov tshuaj silicon ib tuj yog $300- $400 siab dua li ntawm metallurgical silicon. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau siv zog tsim cov tshuaj silicon ntau lawm, txawm tias los ntawm kev ua kom tau raws li kev xa tawm thiab kev thov hauv tsev, lossis los ntawm kev txhim kho cov txiaj ntsig kev lag luam ntawm cov tuam txhab hlau silicon, txhim kho cov khoom zoo.
