Silicon hlau hmoov yog cov khoom siv raw nrog cov ntawv thov tseem ceeb hauv ntau qhov chaw, thiab nws ua haujlwm sib txawv hauv ntau daim ntawv thov.
Nyob rau hauv cov ntaub ntawv refractory, hmoov metallurgy kev lag luam, silicon hlau hmoov yog tsuas yog los txhim kho cov khoom kub tsis kam, hnav tsis kam thiab oxidation tsis kam; nyob rau hauv kev lag luam hluav taws xob, silicon hlau hmoov yog kos rau hauv monocrystalline silicon, cov txheej txheem silicon wafers yog dav siv nyob rau hauv high-tech teb, yog ib tug integrated circuit, hluav taws xob cov khoom tseem ceeb raw cov ntaub ntawv; nyob rau hauv metallurgical casting kev lag luam, silicon hlau hmoov yuav siv tau raws li ib tug non-ferrous alloy additives, silicon-steel alloying neeg sawv cev, siv los txhim kho cov hlau hardenability.
Silicon hlau hmoov ntau lawm txoj kev yog plasma txoj kev, tshuaj vapor deposition txoj kev, pob milling txoj kev.
Plasma method: Tom qab dispersing coarse silicon hmoov, cov roj inert xa mus rau hauv plasma arc, uas yog rhuab tam sim ntawd kom cov silicon hmoov evaporate rau hauv silicon vapor, thiab ces condensed kom tau nano-qib silicon hlau hmoov.
Tshuaj vapor deposition txoj kev: Silane decomposed rau hauv silicon thiab hydrogen nyob rau hauv tej yam kev mob, thiab ces condensed sai heev nyob rau hauv lub roj theem ib puag ncig, thiaj li npaj nano-silicon hmoov.
Pob milling txoj kev: Cov kev sib txhuam loj tsim los ntawm kev sib hloov thiab kev sib cuam tshuam ntawm cov khoom yog siv los zom cov khoom siv silicon loj dua rau hauv cov hmoov nano loj. Txawm li cas los xij, cov hmoov hlau silicon uas tsim los ntawm txoj kev no muaj cov ntsiab lus impurity siab thiab cov particle loj faib tsis yooj yim los tswj.
Silicon hlau hmoov muaj ntau yam kev siv hauv ntau lub teb vim nws cov khoom tshwj xeeb thiab kev siv ntau yam. Nyob rau tib lub sijhawm, cov khoom tsim tawm loj thiab dav dav ntawm cov hmoov hlau silicon hmoov muab cov khoom siv raw khoom txaus rau cov lag luam muaj feem xyuam.
