Ferrosilicon bụ ferroalloy nke mejupụtara ígwè na silicon.Ferrosilicon bụ ígwè-silicon alloy mere site na agbaze coke, nchara nchara, na quartz (ma ọ bụ silica) n'ime ọkụ ọkụ eletrik.Ebe ọ bụ na a na-ejikọta silicon na oxygen n'ụzọ dị mfe n'ime silicon dioxide, a na-ejikarị ferrosilicon mee ihe dị ka deoxidizer na ígwè.N'otu oge ahụ, n'ihi na SiO2 na-emepụta ọtụtụ okpomọkụ, ọ bụkwa uru na-eme ka okpomọkụ nke ígwè gbazere n'oge deoxidation dịkwuo elu.N'otu oge ahụ, ferrosilicon nwekwara ike iji dị ka ihe mgbakwunye alloying element, ma na-ejikarị na ala alloy structural steel, spring steel, bearing steel, heat-resistant steel and electric silicon steel.A na-ejikarị Ferrosilicon dị ka onye na-ebelata mmepụta ferroalloy na ụlọ ọrụ kemịkalụ.
Ferroalloy nke nwere ígwè na silicon (na-eji silica, ígwè, na coke eme ihe dị ka ihe eji eme ihe, silicon nke e belatara na okpomọkụ dị elu nke 1500-1800 degrees na-agbaze na ígwè a wụrụ awụ iji mee ka ọkpụkpụ ferrosilicon).Ọ bụ ihe dị mkpa alloy dị iche iche na ụlọ ọrụ na-agbaze.
