1501 Silicon hlau

Silicon hlau 1501belongs rau ib hom high-purity silicon.

Hauv kev lag luam, nws feem ntau yog tsim los ntawm kev txo cov silicon dioxide los ntawm cov pa roj carbon nyob rau hauv lub cub hluav taws xob. Lub purity ntawm silicon ua nyob rau hauv no txoj kev yog 97 ~ 98%, uas yog hu ua metallic silicon. Tom qab melting thiab recrystallizing, impurities raug tshem tawm nrog cov kua qaub kom tau nws cov hlau silicon nrog purity ntawm 99.7-99.8%. Ua kom nws mus rau hauv semiconductor silicon, nws yog ib qhov tsim nyog los hloov nws mus rau hauv cov kua los yog roj daim ntawv uas yooj yim rau purify, thiab ces tau polycrystalline silicon los ntawm distillation thiab decomposition txheej txheem. Yuav kom tau txais high-purity silicon, yuav tsum tau kho purification ntxiv.

Hais txog cov khoom siv silica, kuv lub teb chaws quartzite reserves yog 2.09 billion tons, suav txog 53.35% ntawm kuv lub teb chaws cov peev txheej silica; ntuj quartz xuab zeb yog 1.23 billion tons, accounting rau 31.5%; ua raws li quartz sandstone thiab leeg quartz, uas yog 560 lab tons feem. , 40 lab tons, accounting rau 14.22% thiab 0.93%.

Organic silicon yog ib qho tseem ceeb downstream kev lag luam ntawm industrial silicon. Nws tuaj yeem tsis tsuas yog siv dav hauv kev lag luam raws li cov khoom siv yooj yim, tab sis kuj tuaj yeem hloov kho lwm cov ntaub ntawv los txhim kho lossis txhim kho cov txheej txheem kev ua tau zoo thiab siv tau ntawm cov khoom siv ib txwm siv. Silicone tuaj yeem ua tiav rau plaub yam loj ntawm cov khoom sib sib zog nqus: silicone roj hmab, silicone resin, silicone roj, thiab silane coupling tus neeg sawv cev. Silicone roj hmab muab faib rau hauv chav tsev kub kua nplaum thiab cov kua nplaum kub kub. Cov khoom lag luam qis ntawm cov organic silicon kuj tseem yog cov kua nplaum kub kub thiab cov kua nplaum hauv chav tsev kub.
