1. Muaj pes tsawg
Silicon hlau (metallurgical-qib silicon, mg-si):
Thawj Cheebtsam: Theem nrab (Si) nrog~ 98-99% Purity.
Kev tsis loj: Cov hlau me me ntawm hlau (FE), txhuas (al), calcium (CA), lossis lwm yam.
Tsab ntawv: Qee zaum hu ua "Silicon ntshiab hlau" thaum txuas ntxiv rau cov khoom siv hluav taws xob.
Ferrosilicon (Fesi):
Alloy ntawm hlau thiab silicon: Muaj15-90% siliconLos ntawm qhov hnyav, nrog cov khoom seem uas tseem muaj hlau (FE).
Kev tsis loj: Kab ntawm cov txhuas, calcium, lossis titanium nyob ntawm kev tsim khoom.
Cov txawv: Cov qib qib sib txawv (piv txwv li, 75% FESI rau steelmaking, 45% fesi rau cov khoom).
2. Cov txheej txheem ntau lawm
Silicon Hlau:
Tsim ntawmCarbothermic txoNtawm silica (quartz) hauv hluav taws xob arc.
Cov khoom siv raw: silica (sitio₂) + carbon (Coke / Charcoal).
Tsis muaj hlau ntxiv; Iron imurer tuaj los ntawm cov khoom nyoos.
Ferrosilicon:
Ua los ntawm smeltingSilica nrog hlau ore, seem hlau, lossis zeb teevHauv hluav taws xob arc rauv.
Cov pa roj carbon txo ob qho tib si silica thiab hlau oxides, tsim kom muaj cua tshuab hluav taws xob.
3. Lub cev thiab tshuaj
| Ntiag tug | Silicon Hlau (Mg-Si) | Ferrosilicon (Fesi) |
|---|---|---|
| Silicon Cov Ntsiab Lus | 98-99% SI (Purity Siab) | 15-90% SI (alloy nrog FE) |
| Cov ntsiab lus hlau | Lw (tsawg dua los yog sib npaug rau 1%) | Chaw tivthaiv loj (10-95% fe) |
| Puab | Ingots, lumps, lossis chunks | Granular lossis pob |
| Ceev | High (cua ntshiab siloos) | Qis dua (vim cov ntoo hlau) |
4. Cov Ntawv Thov
Silicon Hlau:
Khoom siv hluav taws xob: Ua kom zoo rauLas-ntshiab silicon (99.999% +)Rau cov semiconductors, hnub ci panels, thiab ICS.
LamOs: Siv rau hauv aluminium alloys (piv txwv li, al-Si rau cov chaw automotive) thiab maglocesium.
Deoxidizer: Ntxiv rau cov hlau thiab cov hlau cam khwb cia kom tshem cov pa.
Ferrosilicon:
Steelmaking: Kev siv thawj zaug ua aDeoxidizerThiab alloying tus neeg sawv cev los txhim kho lub zog thiab kub ua kom tsis taus.
Pound: Txhim kho fluhing fluidity thiab tiv thaiv kev sib tsoo.
Tshuaj Kev Lag Luam: Siv nyob rau hauv silicones, kev kho cov dej, thiab synthes synthesis.
5. Tus nqi thiab tuav
Silicon Hlau:
Kim kim dua vim muaj kev xav tau siab (xws li, electronics-qib).
Txo ceev ceev dua ferrosilicon, txo cov nqi xa khoom rau ib chav ntawm silicon.
Ferrosilicon:
Raug nqi rau cov ntawv thov bulned vim yog cov ntsiab lus hlau.
Cov ceev faj ntau dua yuav tsum tau tua tshwj xeeb (piv txwv li, sib sib cais sib cais).
6. Kev Ua Lag Luam thiab Xav Tau
Silicon Hlau:
Tsav los ntawm cov khoom siv hluav taws xob thiab lub zog hluav taws xob txuas ntxiv, semiconductors).
Ua lag luam nyob rau hauv cov qib raws cov qhab nia raws cov kev coj dawb huv (piv txwv li, 98% si rau alloys, 99.9% rau hnub ci).
Ferrosilicon:
Thov khi rau steel ntau lawm (kev tsim kho, kho tsheb, tshuab).
Cov nqi cuam tshuam los ntawm cov hlau ore thiab silicon raw khoom muaj.
