Silicon hlau

Taw qhia rau silicon hlau

 

Silicon hlau, tseem hu ua crystalline silicon lossis muaj silicon, feem ntau yog siv los ua ib qho ntxiv rau cov hlau tsis yog hlau. Silicon hlau yog cov khoom smelted los ntawm quartz thiab coke nyob rau hauv lub cub hluav taws xob. Cov ntsiab lus tseem ceeb ntawm silicon yog kwv yees li 98% (hauv xyoo tas los no, 99.99% Si cov ntsiab lus tseem muaj nyob hauv Silicon hlau), thiab cov impurities ntxiv yog hlau thiab txhuas. , calcium, thiab lwm yam.

Cov khoom siv ntxiv ntawm Silicon hlau muaj xws li silicon hmoov, ntug silicon, dub silicon, Silicon hlau slag, thiab lwm yam. Ntawm lawv, silica hmoov, tseem hu ua silica fume, microsilica fume los yog silica fume, yog dav siv nyob rau hauv refractory thiab qhob industries.

 

Classification ntawm Silicon hlau

 

Kev faib tawm ntawm Silicon hlau feem ntau yog raws li cov ntsiab lus ntawm peb lub ntsiab impurities ntawm hlau, txhuas, thiab calcium uas muaj nyob rau hauv Silicon hlau tivthaiv. Raws li cov ntsiab lus ntawm hlau, txhuas, thiab calcium hauv Silicon hlau, Silicon hlau tuaj yeem muab faib ua ntau qib xws li 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, thiab 1101.

Industrially, Silicon hlau feem ntau yog tsim los ntawm kev txo silica nrog cov pa roj carbon nyob rau hauv lub cub hluav taws xob. Cov tshuaj tiv thaiv kab mob sib npaug: SiO2 + 2C → Si + 2CO Lub purity ntawm silicon ua li no yog 97 ~ 98%, uas yog hu ua Silicon hlau. Tom qab ntawd nws yog melted thiab recrystallized, thiab impurities raug tshem tawm nrog acid kom tau Silicon hlau nrog ib tug purity ntawm 99.7 ~ 99.8%.

Kev siv cov hlau silicon

1, Kev npaj cov khoom siv high-purity semiconductor

Silicon hlau yog siv rau: ua cov khoom siv high-purity semiconductor thiab silicon hlau nrog purity ntawm 99.999 (5N). Nws yog industrially purified elemental silicon. Nws yog tsuas yog siv los tsim cov organic silicon thiab siv nyob rau hauv 3C kev lag luam los tsim cov khoom siv hluav taws xob siab purity semiconductor. Tsis tas li ntawd, nws tseem tuaj yeem siv rau hauv ntau yam kev siv xws li kev tsim cov alloys nrog kev siv tshwj xeeb. Ntawm lawv, cov qib qis yog siv cov khoom siv hlau alloy - aluminium-silicon alloys, silicon tooj dag alloys, silicon bronze alloys, thiab lwm yam.

2, Npaj alloy

Formulated alloys: Silicon-aluminium alloys yog cov feem ntau siv silicon alloys. Silicon-aluminium alloy yog ib qho muaj zog sib xyaw deoxidizer. Hloov cov ntshiab txhuas hauv cov txheej txheem steelmaking tuaj yeem txhim kho kev siv tus nqi ntawm deoxidizer, purify molten steel, thiab txhim kho steel zoo.

3, Optical fiber ntau cov ntaub ntawv sib txuas lus

Optical fiber kev sib txuas lus cov khoom siv ntshiab silica tuaj yeem kos rau hauv cov iav fiber ntau pob tshab, uas yog cov khoom tseem ceeb rau kev sib txuas lus fiber ntau. Txoj kev sib txuas lus no hloov cov kab loj loj, muaj peev xwm sib txuas lus siab, tsis raug hluav taws xob thiab sib nqus cuam tshuam, thiab tsis ntshai Eavesdropping, nrog kev ceev ceev ceev. Kev sib txuas lus fiber ntau tau hloov pauv tib neeg lub neej.

4, High kub resistant cov ntaub ntawv

Cov ntaub ntawv kub-resistant Silicon tuaj yeem siv los ua cov ntaub ntawv sib xyaw cermet. Cov khoom no tau txais txiaj ntsig zoo ntawm cov hlau thiab ceramics, thaum tseem ua rau lawv qhov tsis txaus. Nws muaj qhov zoo ntawm qhov kub-kub kuj, toughness, thiab cutability.

5, Kev lag luam hluav taws xob

Kev lag luam Electronics Silicon hlau yog dav siv hauv kev lag luam hluav taws xob. Ua ntej ntawm tag nrho cov, silicon hlau yog ib qho tseem ceeb raw khoom rau kev tsim khoom semiconductor, uas yuav ua tau ntau yam transistors, integrated circuits thiab lwm yam khoom siv hluav taws xob.

6, Kev tsim kho kev lag luam

Kev tsim kho kev lag luam Silicon hlau kuj muaj cov ntawv thov hauv kev tsim kho kev lag luam. Ua ntej tshaj plaws, silicon hlau tuaj yeem siv los ua cov khoom siv raw rau kev tsim iav thiab ceramics, uas tuaj yeem txhim kho cov khoom zoo thiab kev ua haujlwm. Thib ob, silicon hlau tseem xav tau hauv cov khoom siv hauv tsev, xws li cement, pob zeb, thiab lwm yam.
