Ferrosilicon yog ib qho tseem ceeb ntawm cov hlau siv hauv kev tsim cov hlau thiab lwm yam hlau. Nws yog tsim los ntawm hlau thiab silicon, nrog rau ntau qhov sib txawv ntawm lwm cov ntsiab lus xws li manganese thiab carbon. Cov txheej txheem tsim khoom ntawm ferrosilicon suav nrog kev txo qis ntawm quartz (silicon dioxide) nrog coke (carbon) nyob rau hauv muaj hlau. Cov txheej txheem no yuav tsum muaj qhov kub thiab txias thiab siv zog, ua rau cov nqi raw khoom yog qhov tseem ceeb hauv kev txiav txim siab tag nrho cov nqi tsim khoom ntawm ferrosilicon.

Ferrosilicon yog dav siv nyob rau hauv steel kev lag luam, foundry kev lag luam thiab lwm yam industrial ntau lawm. Lawv haus ntau tshaj 90% ntawm ferrosilicon. Ntawm ntau qib ntawm ferrosilicon, 75% ferrosilicon yog qhov siv dav tshaj plaws. Hauv kev lag luam steel, kwv yees li 3-5kg 75% ferrosilicon yog siv rau txhua tuj ntawm cov hlau tsim.

Ferrosilicon nitride thiab silicon nitride suab zoo li ob yam khoom zoo sib xws, tab sis qhov tseeb, lawv yog qhov sib txawv. Kab lus no yuav piav qhia qhov txawv ntawm ob qho tib si los ntawm ntau lub kaum ntse ntse.

Titanium tsis yog magnetic.Qhov no yog vim hais tias titanium muaj ib tug siv lead ua qauv uas tsis muaj unpaired electrons, uas yog tsim nyog rau ib yam khoom los nthuav cov hlau nplaum. Qhov no txhais tau hais tias titanium tsis cuam tshuam nrog cov hlau nplaum thiab suav tias yog cov khoom siv diamagnetic.

Titanium thiab Ferrotitanium / ^ / ^ Titanium nws tus kheej yog ib qho kev hloov pauv hlau nrog cov hlau nplaum, feem ntau yog xim nyiaj-grey. Tab sis titanium nws tus kheej tsis tuaj yeem def

Refractory cib yog cov khoom siv ceramic uas feem ntau siv nyob rau hauv qhov kub thiab txias ib puag ncig vim nws tsis muaj combustibility thiab vim hais tias nws yog ib tug zoo insulator uas txo lub zog poob. Refractory cib feem ntau yog tsim los ntawm txhuas oxide thiab silicon dioxide. Nws tseem hu ua "fire brick."
