Ntawm no yog cov lus sib piv lus Askiv ntawmNws yog xim hlau Silicon (metallurgical-qib silicon)ThiabPolycrrystalline silicon, Qhia txog lawv qhov sib txawv hauv kev muaj pes tsawg leeg, kev tsim khoom, thiab kev siv:
1. Lus Txhais & Muaj pes tsawg
| Nws yog xim hlau silicon (mg-si) | Polycrrystalline silicon (poly-si) |
|---|---|
| Kuj huMetallurgical-Qib Silicon(Mg-si). | Lub npe hu uaHnub ci-qibLossisHauv-Qeb-QebSilicon. |
| Muaj~ {98-99% siliconNrog impurities li fe, al, thiab CA. | Ultra-siab huv (Ntau dua los yog sib npaug rau 99.999% SI) Nrog trace impurities (PPM qib). |
| Daim ntawv lub cev: Lumps, granules, lossis hmoov. | Feem ntau tsim tawm raws li granules lossis ingots (rau semiconductors). |
2. Cov txheej txheem ntau lawm
| Nws yog xim hlau silicon | Polycrrystalline silicon |
|---|---|
| Tsim los ntawm kev txo qisQuartzite (Sio₂)Hauv hluav taws xob arc rauv. | Muab tau los ntawmMg-SiNtawm kev ua kom huv ntxiv (piv txwv li, cov siemens txheej txheem, lub txaj ua kom dej reactor). |
| Yuav tsum muaj high-kub metallurgical smelting. | Koom nrog cov tshuaj vapor deposition (CVD) lossis trichlorosilane (hsichli) distillation. |
3. Cov Ntawv Thov
| Nws yog xim hlau silicon | Polycrrystalline silicon |
|---|---|
| - Alloy ntau lawm (piv txwv li, txhuas-silicon rau cov chaw automotive). | - Hnub ci panels (photovoltaic hlwb). |
| - Hlau deoxidizers thiab fungry additives. | - semiconductor Wafers (ICS, microcips). |
| - Tshuaj Pub Noj Rau Silicones thiab Resins. | - High-efficial dolar hlwb (piv txwv li, Perc, HJT). |
4. Cov Khoom Siv & Kev Ua Tau Zoo
| Nws yog xim hlau silicon | Polycrrystalline silicon |
|---|---|
| Nruab Nrab Thermal / Hluav Taws Xob Conductivity. | Kev tshwj xeeb ntawm hluav taws xob conduction (zoo tagnrho rau semiconductors). |
| Tiv taus oxidation tab sis qis zog. | Ultra-dawb huv nrog qhov tsis xws luag rau cov ntawv thov nanoscale. |
| Raug nqi rau kev lag luam alloys. | Cov nqi siab dua vim yog lub zog-ua kom muaj zog. |
5. Cov Lus Sib Tham Sib Txawv
| Yam | Nws yog xim hlau silicon | Polycrrystalline silicon |
|---|---|---|
| Kev coj dawb huv | 98-99% SI | Ntau dua los yog sib npaug rau 99.999% SI |
| Tus nqi | Qi dua | Siab dua |
| Xaus | Alloys, metallurgy, tshuaj lom neeg. | Hnub ci zog, hluav taws xob, duab ICS. |
| Ntau lawm nplai | Loj-teev smelting. | Tshwj xeeb, high-tech ua kom zoo nkauj. |
Vim li cas thiaj xaiv Zhenan?
Nrog30+} xyoo ntawm kev txawj ntse, Zhenan tshwj xeeb hauv kev muab khoomZoo-Zoo Cov Hlau Ntsej SilicoronUa kom cov kev xav tau. Thaum peb tsom mus rau ntawm cov xim hlau-qeb, peb cov neeg koom tes ntseeg peb rau:
Xwm yeem(Fe<0.1%, Al <0.1%).
Cov ntawv pov thawj hauv ntiaj teb(ASTM, ISO, ROHS).
Kev cai daws teeb meemRau alloys, casting, thiab tshuaj synthesis.
Rau cov ntawv thov polycrystalline, zhenan koom tes nrog cov neeg muag khoom ntseeg kom ntseeg tau tias xaus kev muab khoom siv Saw.
