Cerium yog ib hom hlau uas tsis tshua muaj hauv ntiaj teb uas paub txog nws lub peev xwm los ua kom muaj kev kub ntxhov hauv huab cua, nrog rau kev siv hauv kev tsim cov cerium oxide, uas yog siv los ua polishing compound. Nws yog ib tug mos, silvery-dawb hlau uas feem ntau ua nyob rau hauv daim ntawv ntawm ingots los yog hmoov.
Cubes ntawm cerium hlau tuaj yeem tsim los ntawm ntau txoj hauv kev, xws li casting lossis txiav los ntawm cov khoom loj. Cerium hlau yog cov mos mos thiab tuaj yeem ua tau yooj yim, yog li nws tuaj yeem ua rau ntau hom ntawv los ntawm cov txheej txheem xws li milling, tig, lossis sib tsoo.
Cerium muaj ntau yam kev siv tau vim nws cov khoom tshwj xeeb. Nws feem ntau yog siv los ua cov khoom siv hluav taws xob hauv kev tsim cov roj av thiab lwm yam roj, thiab tseem siv rau hauv kev tsim cov ceramics, iav, thiab lwm yam ntaub ntawv. Nws kuj tseem siv rau hauv kev tsim cov alloys, vim nws tuaj yeem txhim kho corrosion kuj thiab lub zog ntawm lwm yam hlau.
Vim nws reactivity nrog oxygen, cerium hlau feem ntau khaws cia rau hauv ib qho chaw inert los yog hauv qab roj los tiv thaiv oxidation.

Daim ntawv thov

Catalysts nyob rau hauv automotive emission tswj: Cerium yog dav siv nyob rau hauv automotive catalytic converters. Nws ua raws li cov catalyst los txhawb cov oxidation ntawm carbon monoxide thiab hydrocarbons, nrog rau txo nitrogen oxides (NOx) hauv cov pa pa. Qhov sib ntxiv ntawm cerium txhim kho qhov ua tau zoo ntawm cov hloov pauv no, pab kom ua tau raws li cov kev cai ib puag ncig nruj thiab txo cov pa phem los ntawm tsheb.
iav thiab ceramic ntau lawm: Cerium oxide yog muab los ntawm cov ntshiab cerium thiab yog siv los ua polishing tus neeg sawv cev hauv iav thiab ceramic industries. Nws cov khoom zoo tuaj yeem ua tau zoo polished nto ntawm iav, muab qhov zoo tshaj plaws nto tiav. Tsis tas li ntawd, cerium tebchaw yog siv los txhim kho cov khoom siv kho qhov muag ntawm iav, xws li UV nqus thiab txhim kho xim, ua rau nws muaj txiaj ntsig hauv kev tsim cov khoom tshwj xeeb iav.
Alloying tus neeg sawv cev: Pure cerium yog siv los ua tus neeg sawv cev alloying rau ntau yam hlau, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov hlau tsis tshua muaj hauv ntiaj teb mischmetal. Qhov no alloying txhim kho cov khoom siv kho tshuab thiab corrosion kuj ntawm cov hlau, ua rau nws haum rau siv hauv aerospace, automotive thiab lwm yam kev lag luam siab. Qhov sib ntxiv ntawm cerium nce lub zog thiab kav ntev ntawm cov alloys.
Zog Cia thiab Hloov: Cerium tab tom tshawb nrhiav siv rau hauv lub zog cia, tshwj xeeb tshaj yog redox flow batteries. Cerium lub peev xwm los mus rau ob qho tib si oxidation thiab txo cov tshuaj tiv thaiv ua rau nws muaj peev xwm sib tw rau kev txhim kho kev ua tau zoo thiab muaj peev xwm ntawm cov khoom siv hluav taws xob no. Daim ntawv thov no yog qhov tseem ceeb rau kev txhawb nqa cov thev naus laus zis thev naus laus zis tshiab thiab txhim kho kev tswj hwm kev daws teeb meem.
