Cerium oxide, tseem hu ua ceria, yog cov khoom siv ntau yam thiab siv dav nrog ntau yam kev siv thoob plaws ntau yam lag luam. Cov tshuaj no, uas muaj cerium thiab oxygen, muaj cov khoom tshwj xeeb uas ua rau nws muaj txiaj ntsig rau ntau lub hom phiaj.
Kev faib tawm ntawm cerium oxide:
Cerium oxide yog cais raws li lub ntiaj teb tsis tshua muaj hlau oxide, teej tug mus rau lanthanide series ntawm cov ntsiab lus. Nws yog lub teeb daj rau cov hmoov dawb nrog cov thermal stability thiab zoo heev catalytic zog. Cerium oxide feem ntau pom muaj nyob rau hauv ob hom: cerium (III) oxide thiab cerium (IV) oxide. Cerium (III) oxide yog siv los ua ib qho catalyst thiab hauv kev tsim cov iav, thaum cerium (IV) oxide yog siv nyob rau hauv kev tsim cov polishing tebchaw thiab ua catalyst nyob rau hauv ntau yam tshuaj.
Kev siv cerium oxide:
Cerium oxide muaj ntau yam kev siv vim nws cov khoom tshwj xeeb. Ib qho kev siv ntau tshaj plaws ntawm cerium oxide yog nyob rau hauv kev tsim cov catalytic converters rau tsheb. Nws yuav pab txo qis cov pa phem los ntawm kev hloov cov pa phem rau hauv cov khoom tsis zoo. Tsis tas li ntawd, cerium oxide yog siv rau hauv kev tsim cov iav, vim nws tuaj yeem txhim kho cov khoom siv kho qhov muag thiab ua rau muaj zog tiv thaiv UV hluav taws xob. Nws kuj yog siv los ua polishing tus neeg sawv cev rau iav, ceramics, thiab hlau, muab ib tug du thiab reflective nto.
Tsis tas li ntawd, cerium oxide yog siv nyob rau hauv kev tsim cov roj hlwb, qhov uas nws ua raws li ib tug electrolyte los pab txhawb kev hloov ntawm tshuaj zog rau hauv hluav taws xob lub zog. Hauv kev lag luam tshuaj, cerium oxide nanoparticles tau pom tias muaj peev xwm siv tau rau hauv kev siv tshuaj biomedical, xws li kev xa tshuaj thiab kev siv tshuaj. Tsis tas li ntawd, cerium oxide yog siv nyob rau hauv zus tau tej cov phosphors rau fluorescent teeb pom kev zoo thiab nyob rau hauv lub synthesis ntawm ntau yam organic tebchaw.
Hauv kev xaus, cerium oxide yog cov khoom tseem ceeb nrog ntau yam kev siv thoob plaws ntau qhov kev lag luam. Nws cov khoom tshwj xeeb, suav nrog catalytic, kho qhov muag, thiab cov yam ntxwv hluav taws xob, ua rau nws yog ib qho tseem ceeb hauv kev tsim khoom ntawm ntau yam khoom thiab thev naus laus zis. Raws li kev tshawb fawb thiab kev loj hlob hauv nanotechnology thiab cov ntaub ntawv kev tshawb fawb txuas ntxiv mus, cov peev txheej siv cerium oxide zoo li yuav nthuav dav, ntxiv qhov tseem ceeb ntawm kev lag luam niaj hnub no.
