Cerium isimbi isingawanzo kuve inozivikanwa nekugona kwayo kuti ishandise zvoga mumhepo, pamwe nekushandiswa kwayo mukugadzirwa kwe cerium oxide, iyo inoshandiswa seyakaiputika. Icho chakapfava, silvery-chena simbi inowanzogadzirwa muchimiro chengiroke kana poda.
Cebes of cerium simbi inogona kugadzirwa kuburikidza nenzira dzakasiyana siyana, dzakadai sekukanda kana kucheka kubva pamipiro yakakura. Masimbi majee akanyorova uye anogona kunyorwa nyore, saka zvinogona kuumbwa mumhando dzakasiyana siyana kuburikidza nemaitiro akadai sekugera, kutendeuka, kana kugeza.
Cerium ine nhamba yezvingaitika zvinokonzeresa nekuda kwezvivakwa zvaro zvakasarudzika. Zvinowanzoshandiswa sechairisa mukugadzirwa kwepeturu uye dzimwe mafuta, uye rinoshandiswawo mukugadzirwa kweCeramics, girazi, uye zvimwe zvinhu. Izvo zvinoshandiswawo mukugadzirwa kwemadhiri, sezvazvinogona kugadzirisa basa rekumanikidza uye simba redzimwe simbi.
Nekuda kwekugadzirisa kwayo neokisijeni, masimbi marara anowanzochengetwa mune inertemphere kana pasi peoiri kudzivirira oxidation.

Application

CATALYSTS mune automotive emission control: Cerium inoshandiswa zvakanyanya mune emagetsi emagetsi catalytic vashanduri. Inoita seyakaringana kusimudzira oxidation ye carbon monoxide uye hydrocarbons, pamwe nekuderedza nitrogen oildes (nox) mumagasi anopera simba. Kuwedzerwa kwechibvumirano kunokonzeresa kugona kwevatendeki ava, kubatsira kusangana nemitemo yakasarudzika yezvakatipoteredza uye kuderedza zvinokuvadza kubva mumotokari.
Girazi uye ceramic kugadzirwa. Zvimedu zvaro zvakanaka zvinogona kupukutisa pasi pegirazi, kupa yakakwirira-yemhando yepamusoro yekupera. Mukuwedzera, ma cerium comalogs anoshandiswa kuvandudza iyo Optical Properties yegirazi, yakadai seUV yekudzora uye kuvandudza kwemavara, kuchiita kuti ive yakakosha mukugadzirwa kwehurema hwegirazi.
Agent Agent. Uku kugoverwa kunovandudza midziyo yemakekisi uye kupokana kwesimbi, zvichiita kuti zviite kuti ishandiswe muEerospace, motokari uye mamwe maindasitiri akakwirira. Kuwedzerwa kweseka kunowedzera simba uye kujaira kweaya alloys.
Kuchengetedza simba uye kutendeuka: Cerium iri kuongororwa kuti ishandiswe mune simba rekuchengetedza masisitimu, kunyanya redox kuyerera mabhatiri. Kugona kwaChiwi Ichi chishandiso chakanyanya kutsoropodza kufambira mberi gadziriso yekuvandudza simba rezvematongerwo enyika uye kuwedzera simba manejimendi mhinduro.
