Silicon hlau 553

Silicon hlau yog nyiaj grey los yog tsaus grey hmoov nrog cov hlau nplaum, uas yog lub siab melting point, zoo tshav kub tsis kam, siab resistivity thiab superior oxidation kuj, uas yog ib qho tseem ceeb heev cov khoom lag luam yuav siv tau nyob rau hauv steel-ua, cam khwb cia hlau, txhuas. (aviation, aircraft & tsheb qhov chaw tsim khoom), thiab silicon optoelectronic ntaus ntawv thiab ntau lwm yam lag luam. Nws yog tsim los ntawm quartz thiab coke nyob rau hauv hluav taws xob cua sov rauv smelting khoom. Cov khoom tseem ceeb ntawm silicon cov ntsiab lus yog li 98%. Cov seem ntawm impurities yog hlau, txhuas thiab calcium thiab lwm yam.

Daim ntawv thov:
1) Txhim kho qhov kub tsis kam, hnav tsis kam thiab oxidation kuj nyob rau hauv cov khoom siv refractory thiab fais fab metallurgy kev lag luam
2) Cov khoom siv raw uas siab polymer ntawm cov organic silicon formatting.
3) Industrial silicon hmoov yog sublimated rau hauv monocrystalline silicon, uas yog dav siv nyob rau hauv highttech teb raws li ib tug tseem ceeb raw khoom rau integrated circuit thiab hluav taws xob khoom.
4) Nyob rau hauv metallurgy thiab foundry kab, industrial silicon hmoov yog suav hais tias yog hlau puag alloy additive, lub alloy kws tshuaj ntawm silicon steel, yog li txhim kho cov hlau hardenability.
5) Cov no yog siv nyob rau hauv high-temperature khoom tsim nyob rau hauv thiaj li yuav tsim enamels thiab pottery. Cov no kuj ua raws li qhov xav tau ntawm kev lag luam semiconductor los ntawm kev tsim cov khoom siv ultra-ntshiab silicon wafers.
