Cov lus qhia ntxaws ntxaws
CERINE DOOXIDE, tseem hu ua Ceria lossis Cee (IV) oxide, yog ib qho inorganic compound nrog cov tshuaj noj cov mis CEO2. Nov yog qee cov ntsiab lus tseem ceeb txog cerium dioxide:
Khoom:
Zog:Nws yog daj ntseg daj-dawb crystalline khoom.
Tus qauv:CERIT DOXEXIDE Admorite Crystal cov qauv siv lead ua, qhov twg txhua qhov ion yog ib puag ncig los ntawm yim oxygen ions, sib sau ua ke cubic lattice.
Siab melting taw tes: Nws muaj lub ntsiab lus melting ntawm ib ncig 2,550 degrees Celsius (4,622 degrees Fahrenheit).
Insolubility: Cerium dioxide yog insoluble hauv dej tab sis tuaj yeem hnov mob nrog cov acids muaj zog los tsim Cryfts.
Daim ntawv thov
Catalyst: Cerium Dioxide yog dav siv ua catalyst hauv ntau cov txheej txheem muaj. Nws ua rau cov khoom ua haujlwm redox thiab tuaj yeem koom nrog hauv kev siv oxidation thiab txo qis. Nws cov ntawv thov feem ntau yog ua rau catalyst rau cov pa hluav taws xob kev ua kom zoo xws li cov pa roj carbon monoxide thiab nitrogen oxides.
Tus neeg saib xyuas polishing:Vim nws lub siab tawv, cerium dioxide yog siv los ua polishing compound rau iav, hlau, thiab sicemonductor chaw. Nws yog lub npe hu rau nws muaj peev xwm tshem tawm cov khawb thiab muab qhov ua kom du, zoo ua tiav.
Cov roj oxide roj hluav taws xob:Cerium Dioxide tau koom rau hauv cov khoom siv oxide uas yog cov khoom siv hluav taws xob. Nws pab txhim kho kev ua tau zoo thiab kev ruaj khov ntawm cov roj roj.
UV AbsorBER:Cerium dioxide nanoparticles nanoparticles tsim los tiv thaiv cov tawv nqaij los ntawm kev phom sij ultraviolet (UV) hluav taws xob. Lawv ua raws li UV nqus, hloov pauv lub zog nqus kom muaj kev puas tsuaj.
Oxygen Cia:CERIT DOXEXIDE muaj peev xwm khaws thiab tso cov opygen nyob ntawm ib puag ncig ib puag ncig. Cov cuab yeej no ua rau nws muaj txiaj ntsig zoo xws li cov ntawv thov xws li cov lej oxygen, roj cells, thiab cov pa oxygen cia khoom.
Cerium dioxide feem ntau tau txiav txim siab muaj kev nyab xeeb thaum daws tau kom raug. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum tau ceev faj thaum ua haujlwm nrog cov khoom zoo los yog hmoov kom tsis txhob nqus tau lossis sib tw nrog tawv nqaij thiab qhov muag.
