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-abrasives e-silicon carbide, izinto zokusetshenziswa ze-fuel cell, izinto ezisetshenziswa uzibuthe unomphela, okokunamathela, izimonyo, irabha, izinsimbi ezihlukahlukene ze-alloy, ama-laser 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 kwangu-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 obalulekile 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.
