Silicon hlau hmoov yog ib daim ntawv zoo, siab dawb paug ntawm silicon uas yog tsim los ntawm kev txo cov silica hauv hluav taws xob arc rauv. Nws muaj cov xim hlau nplaum thiab muaj nyob rau hauv ntau qhov ntau thiab tsawg, ua rau nws haum rau ntau yam kev siv. Silicon yog qhov thib ob ntau tshaj plaws nyob rau hauv lub ntiaj teb crust thiab ua hauj lwm raws li ib tug tseem ceeb raw khoom nyob rau hauv ntau yam sectors, tshwj xeeb tshaj yog nyob rau hauv semiconductor technology, hnub ci zog, thiab metallurgy.

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.

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
