I-Cerium, igama livela kwigama lesiNgesi le-asteroid Ceres. Umxholo we-cerium kuqweqwe lomhlaba umalunga ne-0.0046%, eyona ntlobo ininzi kakhulu phakathi kwezinto ezinqabileyo zomhlaba. I-Cerium ikhona ikakhulu kwi-monazite kunye ne-bastnaesite, kodwa nakwimveliso ye-fission ye-uranium, i-thorium kunye ne-plutonium. Yenye yeendawo eziphambili zophando kwifiziksi nakwizinto zenzululwazi.
Ngokolwazi olukhoyo, i-cerium ayinakwahlulwa phantse kuzo zonke iindawo zesicelo somhlaba ezinqabileyo. Inokuchazwa "njengesityebi kunye nesihle" sezinto ezinqabileyo zomhlaba kunye ne "cerium doctor" ejikelezayo kwisicelo.
I-cerium oxide ingasetyenziswa ngokuthe ngqo njengomgubo wokupolisha, i-fuel additive, i-petroli catalyst, i-gas purifier ephumayo, njl njl. I-silicon carbide abrasives, iiseli zamafutha ekrwada, izixhobo zemagnethi ezisisigxina, iingubo, izinto zokuthambisa, irabha, iintsimbi ezahlukeneyo zealloy, iilaser kunye neentsimbi ezingezizo i-ferrous, njl.
Kwiminyaka yakutshanje, iimveliso ezicocekileyo ze-cerium oxide zisetyenzisiwe kwi-coating of chips kunye nokupholiswa kwee-wafers, izinto ze-semiconductor, njl.; i-high-purity cerium oxide isetyenziswe kwifilimu entsha encinci ye-crystal display (LFT-LED) izongezo, ii-agent zokupholisha, kunye ne-corrosives yesiphaluka; ubunyulu obuphezulu I-Cerium carbonate isetyenziselwa ukuvelisa umgubo ococekileyo wokupolisha kwiisekethe zokupholisha, kunye ne-high-purity cerium ammonium nitrate isetyenziswa njenge-ejenti ephazamisayo kwiibhodi zeesekethe kunye ne-sterilization kunye nokugcinwa kweziselo.
I-Cerium sulfide ingathatha indawo yelothe, i-cadmium kunye nezinye iintsimbi ezinobungozi kwindalo kunye nabantu kwaye zisetyenziswe kwi-pigments. Iyakwazi ukufaka imibala kwiiplastiki ize isetyenziswe nakwimizi-mveliso yepeyinti, i-inki nephepha.
Inkqubo yelaser ye-Ce:LiSAF yilaser yelizwe elomeleleyo ephuhliswe yiMelika. Ingasetyenziselwa ukubona izixhobo zebhayoloji ngokubeka iliso kuxinzelelo lwe-tryptophan, kwaye inokusetyenziswa namayeza.
Ukusetyenziswa kwe-cerium kwiglasi kuyahlukahluka kwaye kuninzi.
I-cerium oxide yongezwa kwiglasi yemihla ngemihla, njengeglasi yezakhiwo kunye nemoto, iglasi ye-crystal, enokunciphisa ukuhanjiswa kwemisebe ye-ultraviolet, kwaye isetyenziswe ngokubanzi eJapan nase-United States.
I-Cerium oxide kunye ne-neodymium oxide zisetyenziselwa ukuchithwa kweglasi, ithatha indawo ye-agent emhlophe ye-arsenic decolorizing, engaphuculi nje ukusebenza kakuhle, kodwa inqanda ukungcoliswa kwe-arsenic emhlophe.
I-Cerium oxide ikwayeyona arhente ibalaseleyo yombala weglasi. Xa iglasi ekhanyayo ene-arhente enemibala enqabileyo yomhlaba ifunxa ukukhanya okubonakalayo kunye nobude obungamaza angama-400 ukuya kuma-700 e-nanometers, ibonisa umbala omhle. Ezi glasi zinemibala zingasetyenziselwa ukwenza izibane zokuqhuba inqwelomoya, ukuhamba ngenqwelomoya, ukuhamba ngeenqwelomoya, iimoto ezahlukeneyo, kunye nemihombiso eyahlukeneyo yobugcisa obuphezulu. Indibaniselwano ye-cerium oxide kunye ne-titanium dioxide inokwenza iglasi ibonakale ityheli.
I-Cerium oxide ithatha indawo ye-arsenic oxide yendabuko njenge-agent ye-fining yeglasi, enokususa amaqamza kwaye ilandele izinto ezinemibala. Inempembelelo ebalulekileyo ekulungiseleleni iibhotile zeglasi ezingenambala. Imveliso egqityiweyo inomhlophe oqaqambileyo, obala kakuhle, ukuphuculwa kwamandla eglasi kunye nokumelana nokushisa, kwaye ngexesha elifanayo liphelisa ukungcoliswa kwe-arsenic kwindalo kunye neglasi.
Ukongeza, kuthatha imizuzu engama-30 ukuya kwengama-60 ukupolisha i-lens ngepolishi ye-cerium oxide ngomzuzu omnye. Ukuba usebenzisa i-iron oxide polishing powder, kuthatha imizuzu engama-30-60. I-Cerium oxide ipolishi yokupholisha ineenzuzo zedosi encinci, isantya sokupolisha ngokukhawuleza kunye nokusebenza kakuhle kokupholisha, kwaye inokutshintsha umgangatho wokupolisha kunye nokusingqongileyo okusebenzayo. Isetyenziswa kakhulu ekupholiseni iikhamera, iilensi zekhamera, iityhubhu zemifanekiso yeTV, iilensi zokubukela, njl.
