Kev Piav Qhia & Nta

Piav Qhia: WNX siv cov thev naus laus zis tsim khoom tsis siv neeg thiab siv cov khoom siv raw zoo los tsim cov khoom zooCerium Oxide.

Cov Nta Tseem Ceeb:

Kev Ntshiab Siab:Cerium Oxide tsis muaj cov khoom tsis huv los ntawm cov khoom tsis tshua muaj (xws li hlau, calcium, sodium), thiab cov ntsiab lus tsis huv yog tsawg.

Kev yaj zoo:Cerium Oxide tuaj yeem yaj sai sai hauv dej thiab cov kua qaub muaj zog.

Kev sib xws: Kev tswj hwm cov khoom nruj hauv kev tsim khoomCerium Oxide ua kom ruaj khov zoo rau kev lag luam loj.

Kev txhuam kom raug: Cerium oxide yog cov khoom siv txhuam iav zoo tshaj plaws, siv dav hauv kev ua cov iav koob yees duab, iav tsom iav, cov cuab yeej kho qhov muag, cov ntawv ci semiconductor (kev txhuam tshuaj lom neeg CMP), thiab lwm yam. Nws tuaj yeem ua tiav qhov chaw du thiab du los ntawm kev ua tshuaj lom neeg thiab kev kho tshuab.

Kev Ua Kom Ib Puag Ncig Zoo: Hauv kev ntxuav cov pa tawm ntawm lub tsheb (peb txoj kev catalytic converter), cerium oxide ua haujlwm ua ib qho tseem ceeb, khaws cia thiab tso tawm cov pa oxygen, pab txhawb kev hloov pauv ntawm carbon monoxide (CO), hydrocarbons (HC), thiab nitrogen oxides (NOx) mus rau hauv cov pa roj carbon dioxide, nitrogen, thiab dej uas tsis muaj teeb meem. Nws kuj tseem siv rau hauv kev kho cov pa tawm hauv kev lag luam thiab kev hloov pauv dej-roj, thiab lwm yam.

Kev Lag Luam Iav: Hauv cov txheej txheem tsim iav, cerium oxide ua ntau lub luag haujlwm: (1) Tus neeg sawv cev dawb: Nws oxidizes cov hlau divalent ntsuab hauv iav mus rau hauv cov hlau trivalent sib dua, ua rau iav pob tshab dua; (2) Tus neeg sawv cev kom pom tseeb: Nws tshem tawm cov npuas ntawm cov iav yaj; (3) Tus neeg nqus UV: Nws nqus cov duab ultraviolet thiab siv los ua iav tiv thaiv hnub thiab qhov rai aerospace. Nws kuj tseem tuaj yeem sib xyaw nrog titanium dioxide los ua kom xim iav.

Zog thiab Khoom Siv Hluav Taws Xob: Vim nws cov ionic conductivity thiab stability, cerium oxide yog ib qho khoom siv electrolyte tseem ceeb rau cov roj cell solid oxide (SOFCs). Hauv kev lag luam hluav taws xob, nws yog siv los tsim cov khoom siv hluav taws xob ceramic xws li capacitors thiab piezoelectric ceramics.
