Cov alloys uas muaj ntau tshaj 14 feem pua rau 99 feem pua silicon, nrog rau qhov seem yog impurities lossis lwm yam (lossis ob) cov ntsiab lus tseem ceeb, feem ntau hu ua silicon cov khoom los ntawm smelting. Feem ntau suav nrog kev lag luam silicon (silicon hlau), ferrosilicon, barium silicate, silicon carbide, calcium silicate, thiab lwm yam. Feem ntau siv yog industrial silicon (silicon hlau) thiab ferrosilicon.
Ob yam hauv qab no yuav tsum tau ua kom tiav rau smelting silicon khoom:
① Ib qho chaw uas muaj peev xwm los ntxuav nws tus kheej ib puag ncig (ib qho chaw uas tseem tso cai rau cov khoom me me ntawm cov pa phem);
② muaj ntau yam khoom siv hluav taws xob tsawg.
Vim muaj kuab paug hnyav, lub zog siv hluav taws xob siv hluav taws xob siv hluav taws xob siv hluav taws xob tsuas tuaj yeem muab faib rau hauv thaj chaw deb, hydropower-nplua nuj (tus kheej thermal power-nplua nuj) thaj chaw, thiab raug txwv tsis pub siv hluav taws xob, nyob rau lub caij qhuav, feem ntau vim muaj kev txwv fais fab thiab kev txiav ntau lawm. los yog kaw.
