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

Cerium yog ib qho malleable, mos, ductile, hlau-grey hlau, me ntsis harder dua txhuas.Nws yog reactive heev: nws tarnishes yooj yim nyob rau hauv cov huab cua, nws oxidizes maj mam nyob rau hauv dej txias thiab sai sai nyob rau hauv dej kub.Nws dissolves nyob rau hauv acids.Nws tuaj yeem hlawv thaum kub lossis khawb nrog rab riam.

Cerium yog cov hlau tsis muaj zog uas yooj yim oxidizes hauv huab cua.Yog li ntawd nws yuav tsum tau muab cia rau hauv cov roj ntxhia los yog cov roj inert.
