🔍 Qhov txawv ntawm Ferrosilicon thiab Silicon Hlau yog dab tsi?

Txawm tias ob leegFerrosiliconthiabSilicon hlauyog nyob ntawm lub caijsilicon (Si)thiab tseem ceeb heev rau kev lag luam niaj hnub, lawv yogcov ntaub ntawv sib txawvnrog sib txawv compositions, zog, ntau lawm txheej txheem, thiab siv.

1. ❗ Silicon Hlau (Si Hlau) yog dab tsi?

✅ Txhais:

Silicon hlau(tseem hu uaSilicon Elementlos yogMetallurgical Silicon) yog antshiab los yog ze - daim ntawv ntshiab ntawm cov tshuaj silicon (Si), feem ntau muaj98% mus rau 99.99% silicon, nrog tsawg heev ntawm impurities.

✅ Xwm:

Ntshiab elemental khoom

Tsis yog-hlau

Cov khoom siv semiconductor

Tsis muaj hlau

✅ Production:

Tsim los ntawmtxo silica (SiO₂, feem ntau yog los ntawm quartz xuab zeb)nrogcarbon (coke)nyob rau hauv ib qho hluav taws xob arc rauv ntawm qhov kub siab heev, thaum tsis muaj hlau.

✅ Common Purity Levels:

98% Si (Metallurgical Qib)

99.5%–99.99% Si (Electronic/High-Purity Grade)

✅ Cov yam ntxwv tseem ceeb:

Nyiaj -grey, ci iab, zoo li nws yog xim hlau

Txhaum

Cov khoom siv hluav taws xob zoo heev thaum ultra- ntshiab

2. ❗ Ferrosilicon (FeSi) yog dab tsi?

✅ Txhais:

Ferrosilicon(tseem hu uaFerro Silicon, Hlau Silicon Alloy, los yogSilicon Ferro) yog acov ferroalloy- sib tov ntawmsilicon (Si)thiabhlau (Fe). Nws feem ntau muaj45% mus rau 90% silicon, nroghlau raws li qhov sib npaug(lub ntsiab tivthaiv).

✅ Xwm:

Alloy (tsis yog cov khoom ntshiab)

Muaj hlau (Fe)ua ib feem tseem ceeb

Ua los ntawm kev txo cov silica (SiO₂) nyob rau hauv lub xub ntiag ntawm hlau ore los yog seem hlau

✅ Cov Qib Siab (los ntawm Silicon Cov Ntsiab Lus):

FeSi 45(40-47% Sijhawm)

FeSi 65(60-67% Sijhawm)

FeSi 75(72-78% Si) -Feem ntau siv dav

FeSi 90(88-92% Sijhawm)

✅ Cov yam ntxwv tseem ceeb:

Greyish, metallic lumps, granules, los yog hmoov

Siv feem ntau hauv metallurgy, tsis yog electronics

Ua raws li deoxidizer, alloying tus neeg sawv cev, thiab inoculant
