Ukulungiswa kwempahla eluhlaza: Izinto zokusetshenziswa eziyinhloko ze-silicon dioxide i-silicon dioxide (SiO2) kanye nama-ejenti anciphisa ukuncibilikisa, njenge-petroleum coke namalahle. Izinto ezingavuthiwe zidinga ukuchotshozwa, phansi nokunye ukucutshungulwa, ukuze kuthuthukiswe isivinini sokusabela kanye nomphumela wokunciphisa.
Ukuncishiswa kokuncibilika: Ngemva kokuxuba izinto zokusetshenziswa, kufakwa esithandweni sikagesi esishisa kakhulu ukuze kuncishiswe ukuncibilika. Emazingeni okushisa aphezulu, i-ejenti enciphisayo ihlangana ne-silica ukukhiqiza insimbi ye-silicon neminye imikhiqizo etholakalayo, njenge-carbon monoxide. Inqubo yokuncibilika idinga ukulawula izinga lokushisa, umkhathi kanye nesikhathi sokusabela ukuze kuqinisekiswe ukusabela okuphelele.
Ukuhlukaniswa nokuhlanzwa: Ngemva kokupholisa, umkhiqizo oncibilikisiwe uyahlukaniswa futhi uhlanzwe. Izindlela ezibonakalayo, njengokuhlukaniswa kwamandla adonsela phansi kanye nokuhlukaniswa kazibuthe, ngokuvamile zisetshenziselwa ukuhlukanisa insimbi ye-silicon emikhiqizweni. Khona-ke izindlela zamakhemikhali, ezifana nokugeza nokuchithwa kwe-asidi, zisetshenziselwa ukususa ukungcola nokuthuthukisa ukuhlanzeka kwensimbi ye-silicon.
Ukwelashwa kokucwenga: Ukuze kuthuthukiswe ubumsulwa kanye nekhwalithi yensimbi ye-silicon, ukwelashwa kokucwenga kuyadingeka. Izindlela zokucwenga ezivame ukusetshenziswa zifaka indlela ye-redox, indlela ye-electrolysis nokunye. Ngalezi zindlela, ukungcola kwensimbi ye-silicon kungasuswa, futhi ubumsulwa bayo kanye nesakhiwo se-crystal singathuthukiswa.
Ngemuva kwalezi zinyathelo ezingenhla, insimbi ye-silicon etholakalayo ingaphinde icutshungulwe ibe yimikhiqizo yomumo nokucaciswa okuhlukene. Imikhiqizo ejwayelekile ihlanganisa ama-silicon wafers, ama-silicon rods, i-silicon powder, njll., asetshenziswa ku-electronics, photovoltaics, amandla elanga neminye imikhakha. Kodwa-ke, kufanele kuqashelwe ukuthi inqubo yokukhiqiza yensimbi ye-silicon ingahluka ngokuya ngabakhiqizi abahlukene kanye nezidingo zomkhiqizo, futhi izinyathelo ezingenhla ziyisingeniso esifushane senqubo evamile.
