I-Cerium, igama livela egameni lesiNgisi le-asteroid Ceres.Okuqukethwe yi-cerium oqweqweni lomhlaba cishe ku-0.0046%, okuwuhlobo oluningi kakhulu phakathi kwezakhi zomhlaba ezingavamile.I-Cerium ikakhulukazi ikhona e-monazite nase-bastnaesite, kodwa futhi emikhiqizweni ye-fission ye-uranium, i-thorium, ne-plutonium.Ingenye yezindawo ezishisayo zocwaningo ku-physics nesayensi yezinto zokwakha.
Ngokusho kolwazi olutholakalayo, i-cerium ayinakuhlukaniswa cishe kuzo zonke izinkambu zokufaka izicelo zomhlaba ezingavamile.Ingachazwa ngokuthi "icebile futhi inhle" yezakhi zomhlaba ezingavamile kanye "nodokotela we-cerium" osebenza nxazonke.
I-Cerium oxide ingasetshenziswa ngokuqondile njengempushana yokupholisha, isithasiselo sikaphethiloli, i-catalyst kaphethiloli, umgqugquzeli wokuhlanza igesi ephumayo, njll. Ingasetshenziswa futhi njengengxenye ezintweni zokugcina i-hydrogen, izinto ezisetshenziswayo ezishisayo, ama-electrode e-cerium tungsten, ama-ceramic capacitor, izitsha zobumba ze-piezoelectric, i-cerium. ama-silicon carbide abrasives, izinto zokusetshenziswa zamaseli kaphethiloli, izinto zikazibuthe ezihlala unomphela, okokunamathela, izimonyo, irabha, izinsimbi ezihlukahlukene zengxubevange, amalaser nezinsimbi ezingezona ayoni, njll.
Eminyakeni yamuva, imikhiqizo ye-cerium oxide ehlanzekile kakhulu isetshenziswe embotsheni yama-chips kanye nokupholishwa kwama-wafers, izinto ze-semiconductor, njll;i-high-purity cerium oxide isetshenziswa ezithasiselweni ezintsha zefilimu elincanyana le-liquid crystal display (LFT-LED), ama-ejenti wokupholisha, nezinto ezibolayo zesekethe;ukuhlanzeka okuphezulu I-Cerium carbonate isetshenziselwa ukukhiqiza impushana ecwebezelayo ecwebezelayo yeziyingi zokupholisha, futhi i-cerium ammonium nitrate ephezulu yokuhlanzeka isetshenziswa njenge-ejenti egqwalayo yamabhodi esekethe kanye nokuvala inzalo kanye nokulondolozwa kweziphuzo.
I-Cerium sulfide ingathatha indawo yomthofu, i-cadmium nezinye izinsimbi eziyingozi emvelweni nakubantu futhi zisetshenziswe ekwenzeni izingulube.Ingakwazi ukufaka imibala kumapulasitiki futhi ingasetshenziswa nasezimbonini zikapende, uyinki, namaphepha.
Uhlelo lwe-laser lwe-Ce:LiSAF luyi-laser yesifunda esiqinile eyakhiwe yi-United States.Ingasetshenziswa ukuthola izikhali zebhayoloji ngokuqapha ukugcwala kwe-tryptophan, futhi ingasetshenziswa nakwezokwelapha.
Ukusetshenziswa kwe-cerium engilazini kuhlukahlukene futhi kuguquguqukayo.
I-cerium oxide yengezwa engilazini yansuku zonke, njengengilazi yezakhiwo neyezimoto, ingilazi yekristalu, enganciphisa ukudluliswa kwemisebe ye-ultraviolet, futhi iye yasetshenziswa kabanzi eJapane nase-United States.
I-Cerium oxide ne-neodymium oxide isetshenziselwa ukuqeda umbala wengilazi, esikhundleni se-ejenti yendabuko emhlophe ye-arsenic, engathuthukisi ukusebenza kahle nje kuphela, kodwa futhi egwema ukungcoliswa kwe-arsenic emhlophe.
I-Cerium oxide nayo iyi-ejenti yombala yengilazi enhle kakhulu.Lapho ingilazi ebonisa ngale ene-ejenti yombala yomhlaba engavamile idonsa ukukhanya okubonakalayo okunobude obungamaza angama-400 kuya ku-700 nanometers, iveza umbala omuhle.Lezi zibuko ezinemibala zingasetshenziswa ukwenza izibani zokushayela zezindiza, ukuhamba, izimoto ezihlukahlukene, kanye nemihlobiso ehlukahlukene yobuciko bezinga eliphezulu.Inhlanganisela ye-cerium oxide ne-titanium dioxide ingenza ingilazi ibonakale iphuzi.
I-Cerium oxide ithatha indawo ye-arsenic oxide evamile njenge-ejenti yokucwenga ingilazi, engasusa amabhamuza futhi ilandele izakhi ezinemibala.Kunomthelela omkhulu ekulungiseleleni amabhodlela engilazi angenambala.Umkhiqizo oqediwe unomhlophe okhanyayo, obala kahle, amandla engilazi athuthukisiwe nokumelana nokushisa, futhi ngesikhathi esifanayo uqeda ukungcoliswa kwe-arsenic emvelweni nasengilazini.
Ngaphezu kwalokho, kuthatha imizuzu engu-30-60 ukupholisha ilensi nge-cerium oxide polishing powder ngomzuzu owodwa.Uma usebenzisa i-iron oxide polishing powder, kuthatha imizuzu engama-30-60.I-Cerium oxide polishing powder inezinzuzo zemithamo emincane, isivinini sokupholisha ngokushesha nokusebenza kahle kokupholisha, futhi ingashintsha ikhwalithi yokupholisha nendawo yokusebenza.Isetshenziswa kakhulu ekupholishweni kwamakhamera, amalensi ekhamera, amashubhu ezithombe zikamabonakude, amalensi ezibuko, njll.
