Ƙarfe na siliki, wanda kuma aka sani da silicon masana'antu ko silicon silicon, yawanci ana samarwa ta hanyar rage carbon dioxide a cikin tanda na lantarki. Babban amfani da shi azaman ƙari ne don abubuwan da ba na ƙarfe ba kuma azaman kayan farawa don samar da silicon semiconductor da organosilicon.
A kasar Sin, ana rarraba karfen silicon bisa ga abin da ke cikin manyan datti guda uku da ke dauke da su: iron, aluminum da calcium. Dangane da adadin baƙin ƙarfe, aluminum da alli a cikin silicon karfe, ana iya raba silicon karfe zuwa 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101 da sauran maki daban-daban. Lambobin farko da na biyu an ƙididdige su don adadin adadin baƙin ƙarfe da aluminum, kuma lambobi na uku da na huɗu suna wakiltar abun ciki na calcium. Alal misali, 553 yana nufin cewa abun ciki na baƙin ƙarfe, aluminum da calcium shine 5%, 5%, 3%; 3303 yana nufin cewa abun ciki na baƙin ƙarfe, aluminum da calcium shine 3%, 3%, 0.3%).
Samar da ƙarfe na siliki an yi shi ta hanyar hanyar carbothermal, wanda ke nufin cewa siliki da wakili na rage carbonaceous suna narke a cikin tanderun tama. Tsaftar siliki da aka samar ta wannan hanyar shine 97% zuwa 98%, kuma ana iya amfani da irin wannan silicon gabaɗaya a cikin dalilai na ƙarfe. Idan kana so ka sami mafi girman darajar siliki, kana buƙatar tace shi don cire ƙazanta, kuma samun tsarki na 99.7% zuwa 99.8% na silicon karfe.
Ƙarfan siliki mai narkewa tare da yashi ma'adini azaman albarkatun ƙasa ya haɗa da matakai da yawa na yin shingen yashi ma'adini, shirye-shiryen caji da narkar da tanderu.
Gabaɗaya, za a yi amfani da yashi mai inganci kai tsaye wajen samar da samfuran gilashin quartz masu daraja, har ma a sarrafa su zuwa darajar gem kamar crystal, tourmaline da sauran kayayyaki. Matsayin ya ɗan fi muni, amma ajiyar ya fi girma, yanayin hakar ma'adinai ya ɗan fi kyau, kuma wutar lantarki da ke kewaye ya fi rahusa, wanda ya dace da samar da ƙarfe na silicon.
A halin yanzu, Sin ta samar da silicon karfe carbon thermal samar da tsari: da general amfani da silica matsayin albarkatun kasa, man fetur coke, gawayi, itace guntu, low ash kwal da sauran rage jamiái, a cikin tama thermal makera high zafin jiki smelting, rage silicon karfe. daga silica, wanda shi ne slag free submerged baka high zafin jiki narkewa tsari.
Saboda haka, ko da yake ana fitar da ƙarfe na siliki daga siliki, ba duk silica ba ne ya dace da yin karfen siliki. Yashi na yau da kullun da muke gani ba shine ainihin ɗanyen ƙarfe na silicon ba, amma yashin ma'adini da ake amfani da shi wajen samar da masana'antu da aka ambata a sama, kuma ya ɗauki mataki da yawa don kammala rarrabuwa daga yashi zuwa ƙarfe na silicon.
