Si Hlau

Nws tsim nyog taw qhia tias Si Hlau yog ib qho tseem ceeb hauv kev lag luam hluav taws xob. - Nws yog cov khoom siv tseem ceeb rau kev tsim cov siab -purity polycrystalline silicon, thiab cov no yog semiconductors, microcircuits rau cov computers, solar cells. Cov khoom tuaj tawm ntawm lub qhov cub li lava (kub txog 1800 degrees). Tom qab ua tiav txias, nws yog crushed rau hauv me me pieces. Hlau feem ntau yog muag nyob rau hauv daim ntawv ntawm ib daim ntawm 2 hli mus rau 100 hli.

Lub ZhenAn ua silicon hlau nrog cov ntsiab lus siab ntshiab silicon (Si Ntau dua lossis sib npaug li 98.5%). Cov khoom siv raw rau nws cov synthesis yog quartzite (ib qho ntxhia ua los ntawm silicon dioxide, SiO2), nrog rau cov thee thiab ntoo. Nws yog tsim nyob rau ntawm qhov kub ntawm kwv yees li 2000 o C nyob rau hauv tsis kam arc furnaces.

Thaum lub sij hawm tus txheej txheem, feem ntau ntawm cov quartzite (SiO2) yog txo los ntawm carbon (C) rau silicon carbide (SiC), uas yog txo tus neeg sawv cev rau tus so ntawm lub quartz uas tsis hnov ​​mob nyob rau hauv lub electrode arc.

Cov tshuaj tiv thaiv tshuaj zoo li no:

SiO₂ + 2C=Si + 2CO

SiO₂ + 3C=SiC + 2CO (hauv qab ntawm qhov cub)

Qhov kawg tshwm sim tshwm sim saum nruab nrab ntawm lub qhov cub, ntawm qhov kub siab tshaj 1835 degree. Ib qho hluav taws xob arc nyob nruab nrab ntawm qhov kawg ntawm cov electrodes thiab qhov nruab nrab ntawm lub cub tawg tswj kub txog 2000^o C.

Cov theem kawg ntawm cov tshuaj tiv thaiv tshuaj tuaj yeem piav qhia raws li hauv qab no:

2SiO₂ + 3SiC=4Si + SiO +3CO

SiO + SiC=2Si + CO

Cov tshuaj tiv thaiv tom kawg tsim cov silicon ntshiab, uas tau rov qab los ntawm lub cub tawg ua cov hlau nplaum silicon.

Molten silicon hlau yog muab rho tawm los ntawm crucible furnaces, uas yog xa mus rau lub foundry. Nyob ntawd cov ingots raug ntxuav thiab cam khwb cia. Tom qab txias, lawv tau ua ntej- crushed thiab khaws cia rau hauv ib lub qhov cub. Cov khoom yog ces crushed thiab ntim rau hauv daim ntawv no rau kev thauj mus los.

Q: Lub sijhawm khoom xa tuaj ntev npaum li cas rau kev txiav txim ntau?

A: Nws nyob ntawm qhov kev txiav txim kom muaj nuj nqis, feem ntau lub sijhawm xa khoom yuav yog 7-15 hnub ua haujlwm.

Q: Puas muaj kev pabcuam OEM / ODM?

A: Yog, peb txais OEM / ODM.

Q: Yuav ua li cas lav Zoo?

A: Yog, peb muaj kev tswj hwm nruj ntawm qhov zoo los ntawm cov khoom siv raw mus rau cov khoom tiav raws li ISO9001 QC system. Peb lav tag nrho cov khoom yog 100% tsim nyog.

Q: Koj puas yog lub tuam txhab lag luam lossis chaw tsim khoom?

A: Peb yog cov chaw tsim khoom tshaj lij. Peb pab neeg no yog tsim los ntawm cov kws tshaj lij thiab cov kws tshaj lij uas muaj kev paub txog kev paub thiab kev txawj ntse rau lub rooj. Nrog rau kev nkag siab tob txog kev lag luam metallurgical, peb pab neeg ua haujlwm tau zoo ntawm kev tuav txhua yam ntawm kev tsim khoom, kev tswj kom zoo, thiab kev pabcuam rau cov neeg siv khoom.
