Cerium yog lub ntiaj teb tsis tshua muaj neeg hlau uas paub txog nws lub peev xwm los zes rau hauv cerium oxide, uas yog siv ua polishing sib dhos. Nws yog qhov muag muag, silvery-dawb hlau uas feem ntau tsim nyob rau hauv daim ntawv ntawm ingots lossis hmoov.
Cubes ntawm cerium hlau tuaj yeem tsim los ntawm ntau txoj kev, xws li kev ua yeeb yam lossis txiav ntawm kev cuam loj dua. Cerium hlau yog mos thiab tuaj yeem yooj yim machined tau yooj yim machined los ntawm ntau cov ntaub ntawv los ntawm kev ua, tig, tig mus, lossis sib tsoo.
Cerium muaj ntau tus neeg siv cov ntawv thov tau vim nws cov khoom tshwj xeeb. Nws yog feem ntau siv los ua catalyst ntau zus tau tej cov roj thiab lwm cov roj, thiab tseem siv nyob rau hauv cov ceramics, iav, thiab lwm yam ntaub ntawv. Nws kuj yog siv rau hauv kev tsim cov alloys, raws li nws tuaj yeem txhim kho cov corrosion tsis kam thiab lub zog ntawm lwm cov hlau.
Vim nws cov kev cuam tshuam nrog cov pa, cerium hlau feem ntau khaws cia hauv cov khoom hauv inert lossis hauv qab cov roj kom tiv thaiv oxidation.

Daim ntawv thov

Catalysts ntawm kev tswj hwm kev tswj hwm kev tswj hwm: Ceetry tau dav siv nyob rau hauv Automotive catalytic converse. Nws ua raws li catalyst los txhawb cov oxidation ntawm carbon monoxide thiab hydrocarbons, raws li tau txo cov pa nitrogen oxides (NOX) hauv cov roj cua. Qhov sib ntxiv ntawm cerium txhim kho cov kev ua tau zoo ntawm cov confersers no, pab kom tau raws li kev cai nruj ib puag ncig thiab txo cov pa hluav taws xob ib puag ncig ntawm cov tsheb.
Iav thiab Ceramic Ntau Lawm: Cerium oxide yog muab tau los ntawm cerium ntshiab thiab yog siv los ua polishing tus neeg sawv cev hauv lub khob thiab kev lag luam Ceramic. Nws cov khoom zoo tuaj yeem ua kom zoo polish nto rau saum npoo ntawm iav, muab qhov zoo-zoo nto tas. Ib qho ntxiv, cerium teb sib txuas yog siv los txhim kho kho qhov muag ntawm cov iav, xws li UV nqus thiab xim ua haujlwm, ua rau nws muaj txiaj ntsig hauv kev tsim cov khoom lag luam iav tshwj xeeb.
Alloying Tus Neeg Sawv Cev: Cov cerium ntshiab yog siv los ua ib qho kev ua kom zoo rau ntau yam ntawm cov hlau, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov hauv ntiaj teb tsis tshua muaj cov hlau ua tsis ncaj. Qhov no tso ua ke txhim kho cov khoom siv tshuab thiab corrosion tsis kam ntawm cov hlau, ua rau nws haum rau siv hauv aerospace, tsheb thiab lwm yam kev lag luam hauv kev lag luam. Qhov sib ntxiv ntawm cerium nce lub zog thiab kav ntev ntawm cov alloys.
Lub zog cia khoom thiab hloov dua siab tshiab: Cerium tau tshawb pom rau siv hauv cov khoom siv hluav taws xob, tshwj xeeb redox ntws roj teeb. Cerium lub peev xwm los yauv kis las ob zaug thiab txo cov tshuaj tiv thaiv ua rau nws muaj peev xwm sib tw rau kev txhim kho cov khoom siv hluav taws xob kom zoo. Daim ntawv thov no yog qhov tseem ceeb rau kev nce qib dua tshiab thev naus laus zis thiab txhim kho kev daws teeb meem hluav taws xob kev daws teeb meem.
