Ekwenziweni kwezinto zikagesi, i-iron oxide isetshenziswa kakhulu njengengxenye eyinhloko kumadivayisi we-semiconductor, imidiya yokugcina kazibuthe, namadivayisi wokubonisa kagesi.
Amadivayisi we-semiconductor: I-iron oxide ingasebenza njenge-dopant noma ungqimba oluvikelayo kumadivayisi we-semiconductor, okuthinta ukusebenza kanye nezakhiwo zikagesi zezinto.
I-Magnetic storage medium: Iron trioxide (Fe3O4) isetshenziswa kakhulu kuma-hard disk drives nakwamanye amadivaysi okugcina kazibuthe ngenxa yezakhiwo zayo kazibuthe. Njengengxenye ye-magnetic medium, isetshenziselwa ukufundwa kwedatha, ukubhala, nokugcinwa.
Amadivayisi okubonisa ama-elekthronikhi: I-iron oxide isetshenziswa njenge-polarizer pigment kumadivayisi e-liquid display crystal, engalawula isiqondiso sokusakazeka kokukhanya futhi ithuthukise ukusebenza kwesibonisi.
Ukubaluleka kwe-iron oxide ekwenzeni izinto kazibuthe kubonakala kulezi zici ezilandelayo:
Izembatho zikaZibuthe noyinki: Izimibala ze-iron oxide zisetshenziselwa ukwakha izigqoko zikazibuthe noyinki, ongasetshenziselwa ukugcinwa kolwazi, amalebula amelene nokukhwabanisa, kanye nokuvikela izingxenye ze-elekthronikhi.
Izinto eziyinhlanganisela kazibuthe: Izinhlanganisela ze-iron oxide nezinye izinto (njengama-polymers) ukuze zakhe izinto eziyinhlanganisela kazibuthe, ezisetshenziswa kakhulu ekufakweni kwe-elekthronikhi, ukuvikela i-electromagnetic interference (EMI), kanye nezinto zokumunca ama-microwave.
Ama-nanoparticles azibuthe: Ama-nanoparticles e-iron oxide anamandla okusebenza emikhakheni ye-biomedical (njengama-ejenti wokuqhathanisa we-magnetic resonance imaging (MRI)) kanye nobuchwepheshe bokugcinwa kwedatha ngenxa ye-superparamagnetism kanye nokuhambelana kwe-biocompatibility.
I-iron oxide ikakhulukazi ithatha amafomu alandelayo:
I-Ferrous oxide (FeO): ivamise ukubonakala njengento emnyama eqinile, engazinzile, futhi ejwayele ukuqhubekela phambili ne-oxidation ibe ezinye izinhlobo ze-iron oxide emoyeni.
I-Fe2O3: evame ukubizwa ngokuthi i-iron red, iyimpushana enombala onsundu ngokubomvu evame ukusetshenziswa njengesithako sombala, ikakhulukazi kumapendi namapende.
I-Fe3O4, eyaziwa nangokuthi i-magnetite noma i-iron oxide emnyama, iyikristalu emnyama enozibuthe.
Isimo somzimba se-iron oxide singaba yimpushana, izinhlayiya, ibhulokhi noma ikristalu, kuye ngendlela yayo yokuhlanganisa kanye nezidingo zohlelo lokusebenza.
Izakhiwo kazibuthe ze-iron oxide ziyahlukahluka kuye ngokwakhiwa kwamakhemikhali athile:
I-Fe3O4: Okubalulekile kwe-ferromagnetic okunozibuthe oqinile, okuvamise ukusetshenziswa embotsheni kazibuthe, odonsa, namadivayisi wokugcina idatha.
I-iron trioxide (Fe2O3): Ngezinhlobo ezithile (ezifana ne-γ- Fe2O3 ingabonisa uzibuthe obuthaka.
Izakhiwo ze-elekthronikhi ze-iron oxide zibonakala ikakhulukazi emandleni ayo njengempahla ye-semiconductor, ikakhulukazi emkhakheni we-optoelectronics nokugcinwa kwamandla:
Izici ze-Semiconductor: Amanye ama-iron oxides (afana ne-Fe2O3) angasetshenziswa njengama-semiconductors ohlobo lwe-n noma uhlobo lwe-p ngaphansi kwezimo ezithile, ekwenzeni amaseli elanga nezinto ze-photocatalytic.
Ukudluliswa kwenkokhiso: Izici zokudlulisa ukushaja kwe-iron oxide ziyenza isebenze kumadivayisi kagesi, njengama-transistors anemiphumela yenkundla nezinzwa.
I-Magnetic ferrite iyinto ebalulekile kazibuthe, ikakhulukazi eyakhiwe ngama-iron oxides (afana ne-Fe3O4 ne-Fe2O3) namanye ama-oxide ensimbi (afana ne-MnO2, NiO, ZnO, njll.). Lezi zinto zilungiswa ngezinqubo ze-ceramic, okuhlanganisa ukuxuba, ukugaya, ukwakha, ukucwilisa, kanye ne-magnetization.
Ukuxuba: Okokuqala, hlanganisa i-iron oxides namanye ama-oxide ensimbi ngesilinganiso esithile, engeza inani elifanele lokunamathelisa kanye ne-solvent, bese wenza udaka.
Ukubumba: I-slurry yakheka ibe yisimo esifiswayo se-billet ngokucindezela, ukukhipha, noma izindlela zokubumba umjovo.
I-Sintering: I-Sintering umzimba owenziwe ezingeni lokushisa eliphezulu ukuze wenze isakhiwo sekristalu kazibuthe ye-ferrite.
I-Magnetization: I-ferrite ene-sintered ivamise ukudinga ukudonswa uzibuthe ngendawo yangaphandle kazibuthe ukuze ithuthukise izici zayo kazibuthe.
Izinto zikazibuthe ezithambile nezinto zikazibuthe eziqinile yizigaba ezimbili ezinkulu zezinto zikazibuthe, ezidlala izindima ezihlukene ezinhlelweni zikagesi nezikagesi.
Izinto ezithambile zikazibuthe: Lezi zinsiza zinokuphoqelela okuphansi kanye nokufinyeleleka okuphezulu kazibuthe, okuzenza kube lula ukudonsa uzibuthe kanye nokukhipha uzibuthe. Izinto ezithambile zikazibuthe zisetshenziswa kakhulu kuma-transformer, ama-inductors, ukuvikela kazibuthe, namavalvu e-solenoid. Ngokuvamile zakhiwe ngensimbi, i-silicon, kanye nenani elincane lezinye izinsimbi (njenge-cobalt) futhi zingakhiqizwa nge-powder metallurgy noma izinqubo zokwelashwa kokushisa.
Izinto zikazibuthe eziqinile: Izinto eziqinile kazibuthe zinokuphoqelela okuphezulu kanye ne-residual magnetization ephezulu, engagcina uzibuthe isikhathi eside. Lolu hlobo lwento lusetshenziswa kakhulu ukwenza omagnethi abangapheli, njengamamotho, izipikha, ama-hard drive, kanye namadivayisi ahlukahlukene okulungisa kazibuthe. Ukukhiqizwa kwezinto ezinozibuthe eziqinile kuhilela izinqubo eziyinkimbinkimbi, okuhlanganisa ukulungiswa kwempushana enhle, ukwakheka kwengcindezi ephezulu, kanye nokushisa okuphezulu kwe-sintering.
Inzwa kazibuthe: Izinzwa kazibuthe zisebenzisa izinguquko kazibuthe ezintweni kazibuthe ukuze zithole indawo, isivinini, noma isiqondiso sento. Isibonelo, izinzwa ze-Hall effect zisebenzisa izinto kazibuthe ezifana ne-iron oxide ukuthola ubukhona nezinguquko zezinkambu kazibuthe, futhi zisetshenziswa kakhulu ezimotweni, ezishintshayo zezimboni, naku-electronics abathengi.
Amadivayisi esitoreji: Kuma-hard drive nakwamanye amathuluzi okugcina kazibuthe, i-iron oxide (ikakhulukazi i-Fe3O4) isebenza njengendawo kazibuthe yokugcina idatha. Lawa madivaysi afunda futhi abhale ulwazi ngokushintsha isimo sokuzibuthe sezinto ezisebenza kazibuthe.
I-Electromagnetic Compatibility (EMC): Izinto ezisetshenziswa kazibuthe ze-iron oxide zingasetshenziselwa ukuvikela ukuphazamiseka kwe-electromagnetic (EMI), ukuvikela amadivaysi e-electronic ekuphazamisekeni kogesi wangaphandle, futhi kuvimbele ukuphazamiseka okukhiqizwa yidivayisi ngokwayo ekuthinteni amanye amadivaysi. Lezi zinto ngokuvamile zenziwa amakhava okuvikela noma ama-coatings, amboze izingxenye ze-elekthronikhi ezibucayi noma yonke idivayisi.
