Birta Silicon, oo sidoo kale loo yaqaan silikoon warshadeed ama silikoon crystalline, waxaa badanaa lagu soo saaraa kaarboonka silikoon dioxide ee foornooyinka korontada. Isticmaalkeeda ugu weyni waa sida wax lagu daro oo loogu talagalay alloys-ka aan-ferrous-ka ahayn iyo sida alaab bilow ah oo loogu talagalay soo saarista silikon semiconductor iyo organosilicon.
Dalka Shiinaha, birta Silicon waxaa badanaa loo kala saaraa iyadoo loo eegayo waxa ay ka kooban tahay saddexda wasakh ee ugu waaweyn ee ay ka kooban tahay: birta, aluminium iyo calcium. Marka loo eego saamiga boqolkiiba ee birta, aluminium iyo kalsiyum ee silikoon birta ah, Silicon birta waxaa loo qaybin karaa 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101 iyo darajooyin kale oo kala duwan. Nambarada koowaad iyo labaad waxa loo calaamadeeyay boqolkiiba waxa ka kooban birta iyo aluminium, iyo tirooyinka saddexaad iyo afraad waxay matalaan waxa ku jira kaalshiyamka. Tusaale ahaan, 553 waxay ka dhigan tahay in maadada birta, aluminium iyo calcium ay tahay 5%, 5%, 3%; 3303 macneheedu waxa weeye waxa ku jira birta, aluminium iyo calcium waa 3%, 3%, 0.3%)
Soo saarista birta silikoon waxaa lagu sameeyaa habka karbothermal, taas oo macnaheedu yahay in silica iyo wakiilka yaraynta carbonaceous ay ku dhalaalaan foornada macdanta. Nadiifinta silikoon ee habkan loo soo saaray waa 97% ilaa 98%, silikoon noocan oo kale ah ayaa guud ahaan loo isticmaali karaa ujeedooyinka birta. Haddii aad rabto inaad hesho darajo sare oo Silicon ah, waxaad u baahan tahay inaad sifayso si aad wasakhda uga saarto, oo aad u hesho nadiif ah 99.7% ilaa 99.8% silikoon macdan ah.
Qurxinta birta silikoon ee leh ciid quartz sida alaabta ceeriin waxaa ku jira dhowr tillaabo oo ah samaynta block ciid quartz, diyaarinta kharashka iyo dhalaalinta foornada macdanta.
Guud ahaan, ciid quartz tayo sare leh ayaa si toos ah loogu isticmaali doonaa soo saarista alaabta quraaradaha quartz-sare, iyo xitaa laga baaraandegi doono darajada gem sida crystal, tourmaline iyo alaabta kale. Darajada wax yar ayaa ka sii dareysa, laakiin kaydka ayaa ka sii weyn, xaaladaha macdanta ayaa waxoogaa ka sii wanaagsan, korantada ku hareeraysan waa ka jaban tahay, taas oo ku habboon wax soo saarka birta silikoon.
Waqtigan xaadirka ah, wax soo saarka Shiinaha ee silikoon biraha carbon habka wax soo saarka kulaylka: isticmaalka guud ee silica sida alaabta ceeriin, petroleum coke, dhuxusha, chips alwaax, dhuxusha yar yar iyo wakiilada kale ee yaraynta, in foornada kulaylka macdan dhalaalaysa heerkulka sare, yaraynta biraha silicon Laga soo bilaabo silica, taas oo ah geeddi-socod dhalaalid heerkul sare ah oo bilaash ah.
Sidaa darteed, inkasta oo birta silikoon laga soo saaro silica, dhammaan silica kuma habboona samaynta birta silikoon. Ciidda caadiga ah ee aan aragno maalin kasta maaha alaabta ceeriin ee dhabta ah ee birta silikoon, laakiin ciidda quartz ee loo isticmaalo wax soo saarka warshadaha ee kor ku xusan, waxayna soo martay falcelin tallaabooyin badan si ay u dhamaystirto kala daadsanaanta ciidda ilaa birta silikoon.
