Yam ntxwv	Kev piav qhia
Hom	Binary ferroalloy (Si-Fe)
Si cov ntsiab lus	68-72% (nominal 70%)
Fe cov ntsiab lus	Qhov nyiaj tshuav (~ 28–32%)
Main impurities	Al ( Tsawg dua lossis sib npaug 2 %), C ( Tsawg dua lossis sib npaug li 0.2 %), P ( Tsawg dua lossis sib npaug 0.05 %), S ( Tsawg dua lossis sib npaug 0.04 %)
Daim ntawv	Pob (10-80 mm), crushed, granulated, los yog hmoov
Melting point	~ 1230-1290℃(nws txawv nrog cov muaj pes tsawg leeg)
Txoj kev tsim khoom	Carbothermic txo ntawm quartz (SiO₂) nrog coke thiab hlau hauv hluav taws xob arc rauv

Lub luag haujlwm tseem ceeb hauv metallurgy

Deoxidizerhauv steelmaking: Silicon reacts nrog oxygen los ua SiO₂, tshem O yaj ntawm cov hlau molten.

Alloying khoom: Ua kom muaj zog, hardness, thiab sib nqus permeability ntawm hlau.

Inoculant / Nodulizer pabNyob rau hauv cam khwb cia hlau: Txhawb nqa graphite tsim thiab refines grain qauv.

Tus neeg sawv cev txo qisnyob rau hauv non-ferrous hlau ntau lawm.
