Cerium isimbi yepasi isingawanzozivikanwi nekukwanisa kwayo kubatidza yega mumhepo, pamwe nekushandiswa kwayo mukugadzirwa kwecerium oxide, iyo inoshandiswa sechinhu chinopenya. Isimbi yakapfava, chena-chena iyo inowanzogadzirwa nenzira yeingots kana upfu.
Cubes yecerium metal inogona kugadzirwa nenzira dzakasiyana siyana, sekukanda kana kucheka kubva kune yakakura ingots. Cerium simbi yakapfava uye inogona kugadzirwa nyore nyore, saka inogona kuumbwa kuita akasiyana siyana kuburikidza nemaitiro akadai sekugaya, kutendeuka, kana kukuya.
Cerium ine akati wandei anogona kunyorera nekuda kweiyo yakasarudzika zvivakwa. Inowanzoshandiswa sechinhu chinokonzera mukugadzirwa kwepeturu uye mamwe mafuta, uye inoshandiswawo mukugadzirwa kwekeramics, girazi, nezvimwe zvinhu. Inoshandiswawo mukugadzira alloys, sezvo inogona kuvandudza kusimba kwekuora uye kusimba kwemamwe masimbi.
Nekuda kwekuita zvakare neokisijeni, cerium simbi inowanzochengetwa mumhepo inert kana pasi pemafuta kudzivirira oxidation.

Application

Catalysts mumotokari emission control: Cerium inoshandiswa zvakanyanya mumotokari catalytic converters. Inoshanda sechinhu chinokurudzira kusvibiswa kwekabhoni monoxide uye hydrocarbons, pamwe nekuderedza nitrogen oxides (NOx) mumagasi ekupedza. Kuwedzerwa kwecerium kunovandudza kushanda kwevashanduri ava, zvichibatsira kusangana nemitemo yakaoma yezvakatipoteredza uye kuderedza kusvibiswa kunokuvadza kubva kumotokari.
Girazi uye ceramic kugadzirwa: Cerium oxide inotorwa kubva ku pure cerium uye inoshandiswa seye polishing agent mugirazi uye ceramic maindasitiri. Zvimedu zvaro zvakanaka zvinogona kukwenenzvera pamusoro pegirazi, zvichipa kupedzisa kwemhando yepamusoro. Uye zvakare, cerium makomisheni anoshandiswa kuvandudza optical zvimiro zvegirazi, senge UV kunyudzwa uye kuwedzera kwemavara, zvichiita kuti ive yakakosha mukugadzirwa kweakakosha magirazi zvigadzirwa.
Alloying agent: Pure cerium inoshandiswa sechinhu chinosanganisa simbi dzakasiyana-siyana, kunyanya mukugadzirwa kwerare earth metal mischmetal. Iyi alloying inonatsiridza ma mechanic properties uye nekupokana nekuora kwesimbi, ichiita kuti ive yakakodzera kushandiswa mune aerospace, mota uye mamwe maindasitiri epamusoro-soro. Kuwedzerwa kwecerium kunowedzera simba uye kusimba kweaya alloys.
Kuchengetedza Kwesimba uye Shanduko: Cerium iri kuongororwa kuti ishandiswe mumasisitimu ekuchengetedza simba, kunyanya redox kuyerera mabhatiri. Kugona kweCerium kuita zvese oxidation uye kudzikisira kuita kunoita kuti ive mumiriri wekuvandudza kugona uye kugona kweaya masisitimu ekuchengetedza simba. Ichi chishandiso chakakosha kufambisira mberi matekinoroji esimba rinogoneka uye kuwedzera simba rekutonga mhinduro.
