Cerium, lebitso le tsoa lebitsong la Senyesemane la asteroid Ceres. Likahare tsa cerium karolong e ka holimo ea lefatše li ka ba 0.0046%, e leng mefuta e mengata ka ho fetisisa har'a likarolo tse sa tloaelehang tsa lefatše. Cerium e fumaneha haholo monazite le bastnaesite, empa hape le lihlahisoa tsa fission tsa uranium, thorium le plutonium. Ke e 'ngoe ea libaka tsa lipatlisiso ho fisiks le mahlale a thepa.
Ho latela tlhaiso-leseling e fumanehang, cerium ha e arohane hoo e batlang e le libakeng tsohle tse sa tloaelehang tsa ts'ebeliso ea lefats'e. E ka hlalosoa e le "e ruileng le e ntle" ea likarolo tse sa tloaelehang tsa lefats'e le "ngaka ea cerium" e pota-potileng ka kopo.
Cerium oxide e ka sebelisoa ka ho toba e le phofo e benyang, motsoako oa mafura, motlakase oa peterole, motlakase oa ho hloekisa khase, joalo-joalo E ka boela ea sebelisoa e le karolo ea lisebelisoa tsa polokelo ea haedrojene, lisebelisoa tsa thermoelectric, li-electrode tsa cerium tungsten, li-ceramic capacitors, li-ceramics tsa piezoelectric, cerium. li-abrasives tsa silicon carbide, lisebelisoa tse tala tsa lisele tsa mafura, lisebelisoa tsa makenete tse sa feleng, likoaelo, litlolo, rabara, litšepe tse fapaneng tsa alloy, lasers le litšepe tse se nang ferrous, jj.
Lilemong tsa morao tjena, lihlahisoa tse phahameng tsa cerium oxide li 'nile tsa sebelisoa ho roala li-chips le ho belisoa ha li-wafers, lisebelisoa tsa semiconductor, joalo-joalo; high-purity cerium oxide e sebelisoa ho li-additives tse ncha tse tšesaane tsa filimi ea metsi a kristale (LFT-LED), lisebelisoa tsa polishing, le li-corrosives tsa potoloho; bohloeki bo phahameng ba Cerium carbonate e sebelisetsoa ho hlahisa phofo e phahameng ea ho bentša e hloekileng bakeng sa lipotoloho tsa ho bentša, 'me cerium ammonium nitrate e hloekileng haholo e sebelisoa e le ntho e senyang bakeng sa liboto tsa potoloho le ho thibela likokoana-hloko le ho boloka lino tse tahang.
Cerium sulfide e ka nka sebaka sa loto, cadmium le litšepe tse ling tse kotsi tikolohong le bathong mme li ka sebelisoa ho etsa mebala. E ka ’na ea etsa lipolasetiki ka mebala ’me e ka boela ea sebelisoa indastering ea ho penta, enke le ea pampiri.
Sistimi ea laser ea Ce:LiSAF ke laser e tiileng ea naha e ntlafalitsoeng ke United States. E ka sebelisoa ho bona libetsa tsa likokoana-hloko ka ho beha leihlo boemo ba tryptophan, hape e ka sebelisoa le meriana.
Tšebeliso ea cerium ho khalase e fapane ebile e na le mefuta e mengata.
Cerium oxide e eketsoa ka likhalase tsa letsatsi le letsatsi, tse kang khalase ea meralo le ea likoloi, khalase ea kristale, e ka fokotsang phetiso ea mahlaseli a ultraviolet, 'me e sebelisitsoe haholo Japane le United States.
Cerium oxide le neodymium oxide li sebelisoa bakeng sa decolorization ea khalase, ho nkela sebaka sa setso sa khale sa arsenic decolorizing, se sa ntlafatse ts'ebetso feela, empa hape se qoba tšilafalo ea arsenic e tšoeu.
Cerium oxide hape ke moemeli ea khabane oa mebala ea khalase. Ha khalase e bonaletsang e nang le 'mala o sa tloaelehang oa lefatše e monya leseli le bonahalang ka bolelele ba li-nanometer tse 400 ho isa ho tse 700, e hlahisa' mala o motle. Likhalase tsena tse mebala-bala li ka sebelisoa ho etsa mabone a lifofane, ho tsamaea ka sekepe, likoloi tse fapa-fapaneng, le mekhabiso e fapaneng ea maemo a holimo. Motsoako oa cerium oxide le titanium dioxide o ka etsa hore khalase e bonahale e le mosehla.
Cerium oxide e nkela sebaka sa khale sa arsenic oxide e le sesebelisoa sa ho hloekisa likhalase, se ka tlosang lipululana le ho sala morao likarolo tse mebala. E na le phello e kholo ho lokiseng libotlolo tsa khalase tse se nang mebala. Sehlahisoa se phethiloeng se na le bosoeu bo khanyang, pepeneneng e ntle, matla a khalase a ntlafetseng le ho hanyetsa mocheso, 'me ka nako e ts'oanang ho felisa Tšilafalo ea arsenic ho tikoloho le khalase.
Ho feta moo, ho nka metsotso e 30-60 ho bentša lense ka phofo e benyang ea cerium oxide ka motsotso o le mong. Haeba u sebelisa tšepe ea oxide polishing powder, ho nka metsotso e 30-60. Cerium oxide polishing powder e na le melemo ea litekanyetso tse nyane, lebelo la ho bentša ka potlako le bokhoni bo phahameng ba ho bentša, 'me e ka fetola boleng ba ho bentša le tikoloho ea ts'ebetso. E sebelisoa haholo ho bentša lik'hamera, lilense tsa khamera, li-tubes tsa litšoantšo tsa TV, lilense tsa mahlo, joalo-joalo.
