Ferro Silicon waa nooc ka mid ah alloys ferro kaas oo la isku daray silikoon iyo birta. Saamiga labada walxood ee kiimikaad ayaa la isku daray oo kala duwan, iyadoo saamiga silikoonku u dhexeeyo meel kasta inta u dhaxaysa 15% iyo 90%. Ferro Silicon 65 waxay isticmaashaa kookaha, jajabyada birta iyo quartz (ama silica) sida alaabta ceeriin, ka dib marka la yareeyo heerkulka sare ee 1500-1800, silikoonku wuxuu ku dhalaali karaa birta dhalaalaysa si uu u sameeyo silikoon ferro.
Ferro Silicon ee warshadda ferroalloy ee Zhenan waa daawaha ferrosilicon oo ka kooban silikon iyo bir qayb ahaan waxaana inta badan loo isticmaalaa dhalaalinta birta iyo dhalaalinta magnesium-ka birta.
