Yiziphi izinto zokusetshenziswa zokukhiqiza i-polysilicon?

Izinto zokusetshenziswa zokukhiqiza i-polysilicon ikakhulukazi zifaka i-silicon ore, i-hydrochloric acid, i-silicon yezimboni ye-metallurgical grade, i-hydrogen, i-hydrogen chloride, i-silicon powder yezimboni, i-carbon ne-quartz ore..

.I-silicon ore.: ikakhulukazi i-silicon dioxide (SiO2), engakhishwa ku-silicon ores njenge-quartz, isihlabathi se-quartz, ne-wollastonite..I-Hydrochloric acid.(noma i-chlorine ne-hydrogen): isetshenziselwa ukusabela nge-silicon yezimboni yezinga le-metallurgical ukukhiqiza i-trichlorosilane..I-silicon yezimboni ze-Metallurgical grade.: njengenye yezinto zokusetshenziswa, ihlangana ne-hydrochloric acid ezingeni lokushisa eliphezulu ukuze ikhiqize i-trichlorosilane..I-hydrogen.: isetshenziselwa ukunciphisa i-trichlorosilane ukukhiqiza izinduku ze-polysilicon ezihlanzekile kakhulu..I-Hydrogen chloride.: isabela ngempushana ye-silicon yezimboni esithandweni sokuhlanganiswa ukuze ikhiqize i-trichlorosilane..I-silicon powder yezimboni.: i-quartz ore ne-carbon kuyancishiswa ukuze kukhiqizwe amabhulokhi e-silicon yezimboni ngaphansi kwamandla, agaywe abe yimpushana ye-silicon yezimboni..Lezi zinto zokusetshenziswa zibhekana nochungechunge lokusabela kwamakhemikhali kanye nezinqubo zokuhlanza ukuze ekugcineni zithole izinto ezihlanzekile ze-polysilicon. I-Polysilicon iyisisetshenziswa esiyisisekelo sokukhiqiza ama-crystal silicon wafers futhi isetshenziswa kabanzi embonini ye-semiconductor, amaseli elanga neminye imikhakha.

i-polysilicon iyimpahla eluhlaza eqondile yokukhiqiza i-silicon eyodwa yekristalu. Kuyinto eyisisekelo yolwazi lwe-elekthronikhi yamadivayisi e-semiconductor afana nobuhlakani bokwenziwa besimanje, ukulawula okuzenzakalelayo, ukucutshungulwa kolwazi, nokuguqulwa kukagesi wesithombe. Ibizwa ngokuthi "itshe lekhona lesakhiwo se-microelectronics."

Abakhiqizi abakhulu be-polysilicon i-Hemlock Semiconductor, i-Wacker Chemie, i-REC, i-TOKUYAMA, i-MEMC, i-Mitsubishi, i-Sumitomo-Titanium, nabanye abakhiqizi abancane e-China. Izinkampani eziyisikhombisa eziphambili zakhiqiza ngaphezu kwama-75% okukhiqizwa kwe-polysilicon emhlabeni wonke ngo-2006.
