Isitena esichasayo sisixhobo se-ceramic esihlala sisetyenziswa kwiindawo eziphakamileyo zokushisa ngenxa yokungabi nokutsha kwaye ngenxa yokuba sisikhuselo esifanelekileyo esinciphisa ukulahlekelwa kwamandla. Izitena eziphikisayo ngokuqhelekileyo zenziwe nge-aluminium oxide kunye ne-silicon dioxide. Ikwabizwa ngokuba "yisitena somlilo."

Ukuphoswa kwesinyithi bubuchule bakudala obubalulekile kwimpucuko yabantu kangangeenkulungwane. Ukusuka ekudaleni imifanekiso eqingqiweyo entsonkothileyo ukuya kwimveliso entsonkothileyo ye-indus

I-Ferrosilicon yi-ferroalloy ebalulekileyo esetyenziswa ngokubanzi kwi-metallurgy yentsimbi kunye ne-Foundry industry. Eli nqaku liza kwazisa ngokubanzi inkqubo yokuvelisa i-ferrosilicon, kubandakanywa nokukhethwa kwezinto eziluhlaza, iindlela zokuvelisa, ukuhamba kwenkqubo, ukulawula umgangatho kunye nefuthe lokusingqongileyo.

I-alloy ngumxube okanye isisombululo esiqinileyo esiquka isinyithi. Ngokufanayo, i-ferroalloy ngumxube we-aluminiyam exutywe nezinye izinto ezifana ne-manganese, i-alum.

I-silicon yentsimbi yomgubo yinxalenye ebalulekileyo kwishishini lokwenza intsimbi. Isetyenziswa ngokubanzi njenge-agent alloying ekuveliseni iintlobo ezahlukeneyo zetsimbi. Ngeempawu zayo ezizodwa kunye neenzuzo, i-silicon powder powder idlala indima ebalulekileyo ekuphuculeni umgangatho kunye nokusebenza kweemveliso zetsimbi. Eli nqaku lijolise ekunikeni uphando olunzulu lwe-silicon powder yensimbi yokwenza i-steelmaking, igxininisa iimpawu zayo, izicelo, kunye neenzuzo ezinikezelayo kwishishini lensimbi.
