Silicon metal, eo hape e tsejoang e le silicon ea indasteri kapa silicon ea crystalline, hangata e hlahisoa ke phokotso ea khabone ea silicon dioxide liboping tsa motlakase. Tšebeliso ea eona e ka sehloohong ke ho tlatsetsa bakeng sa li-alloys tse se nang ferrous hape e le ntho e qalang bakeng sa tlhahiso ea silicon ea semiconductor le organosilicon.
Chaena, tšepe ea silicon e atisa ho aroloa ho ea ka litaba tsa litšila tse tharo tse ka sehloohong: tšepe, aluminium le calcium. Ho ea ka karolo ea liperesente tsa tšepe, aluminium le k'halsiamo ka silicon ea tšepe, silicon ea tšepe e ka aroloa ka 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101 le limaraka tse ling tse fapaneng. Linomoro tsa pele le tsa bobeli li ngotsoe bakeng sa karolo ea peresente ea tšepe le aluminium, 'me palo ea boraro le ea bone e emela likahare tsa calcium. Ka mohlala, 553 e bolela hore litaba tsa tšepe, aluminium le calcium ke 5%, 5%, 3%; 3303 e bolela hore likahare tsa tšepe, aluminium le calcium ke 3%, 3%, 0.3%).
Tlhahiso ea tšepe ea silicon e entsoe ka mokhoa oa carbothermal, ho bolelang hore silica le carbonaceous re fokotsa agent li qhibilihisoa ka sebōping sa ore. Ho hloeka ha silicon e hlahisoang ka tsela ena ke 97% ho 98%, 'me silicon e joalo e ka sebelisoa ka kakaretso mererong ea metallurgical. Haeba u batla ho fumana boemo bo phahameng ba silicon, u lokela ho e hloekisa ho tlosa litšila, 'me u fumane bohloeki ba 99.7% ho 99,8% ea silicon ea tšepe.
Ho qhibilihisa tšepe ea silicon e nang le lehlabathe la quartz e le lisebelisoa tse tala ho kenyelletsa mehato e mengata ea ho etsa litene tsa lehlabathe la quartz, ho lokisa litefiso le ho qhibilihisa sebōpi sa ore.
Ka kakaretso, lehlabathe la boleng bo phahameng la quartz le tla sebelisoa ka ho toba ha ho etsoa lihlahisoa tsa likhalase tsa quartz tsa boemo bo phahameng, esita le ho sebetsoa hore e be li-gem grade tse kang kristale, tourmaline le lihlahisoa tse ling. Sehlopha se mpefala hanyenyane, empa mehloli e mengata e kholoanyane, maemo a merafo a batla a le betere, 'me motlakase o potolohileng o theko e tlaase, o loketseng tlhahiso ea tšepe ea silicon.
Hajoale, tlhahiso ea China ea silicon metal carbon thermal production process: tšebeliso e akaretsang ea silika e le lisebelisoa tse tala, coke ea petroleum, mashala, mashala a molora, mashala a molora le lisebelisoa tse ling tse fokotsang, ka seboping sa ore e chesang mocheso o phahameng o qhibilihisa, ho fokotsa tšepe ea silicon. ho tloha silica, e leng mokhoa oa ho qhibiliha oa mocheso o phahameng oa slag o sa keneleng metsi.
Ka hona, le hoja tšepe ea silicon e ntšoa ho silika, hase silika eohle e loketseng ho etsa tšepe ea silicon. Lehlabathe le tloaelehileng leo re le bonang letsatsi le leng le le leng ha se thepa ea sebele ea tšepe ea silicon, empa lehlabathe la quartz le sebelisitsoeng tlhahiso ea indasteri e boletsoeng ka holimo, 'me le bile le karabelo ea mehato e mengata ho phethahatsa ho arohana ho tloha lehlabatheng ho ea ho tšepe ea silicon.
