Silicon hlau hmoov yog ntau yam khoom siv nrog ntau yam kev siv hauv ntau yam lag luam. Cov khoom tshwj xeeb ntawm silicon hlau hmoov ua rau nws muaj txiaj ntsig zoo raw khoom rau ntau yam khoom thiab cov txheej txheem. Hauv tsab xov xwm no, peb yuav tshawb xyuas cov khoom tseem ceeb ntawm silicon hlau hmoov thiab delve rau hauv nws cov ntawv thov sib txawv.

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.

Ferromolybdenum yog ferroalloy uas muaj hlau thiab molybdenum. Nws yog tsim los ntawm smelting ib tug sib tov ntawm molybdenum concentrate thiab hlau concentrate nyob rau hauv lub cub tawg. Ferromolybdenum yog ntau yam hlau uas tuaj yeem siv rau ntau yam kev siv thoob plaws kev lag luam sib txawv.

Tungsten-hlau alloys feem ntau yog xa mus rau cov alloys uas muaj tungsten (W) thiab hlau (Fe). Feem ntau hais lus, tungsten-hlau alloys tsis yog hlau nplaum.Qhov no yog vim tungsten nws tus kheej yog cov hlau tsis sib nqus, thiab cov ntsiab lus hlau hauv tungsten-hlau alloys feem ntau qis, uas tsis tuaj yeem muab cov hlau nplaum tseem ceeb.
