Cerium ndi chitsulo chosowa padziko lapansi chomwe chimadziwika kuti chimatha kuyaka mwadzidzidzi mumlengalenga, komanso kugwiritsa ntchito popanga cerium oxide, yomwe imagwiritsidwa ntchito ngati kupukuta. Ndizitsulo zofewa, zoyera zasiliva zomwe nthawi zambiri zimapangidwa ngati ingots kapena ufa.
Ma cubes a zitsulo za cerium amatha kupangidwa kudzera m'njira zosiyanasiyana, monga kuponyera kapena kudula kuchokera ku ingots zazikulu. Chitsulo cha Cerium ndi chofewa ndipo chimatha kupangidwa mosavuta, kotero chimatha kupangidwa m'njira zosiyanasiyana pogwiritsa ntchito njira monga mphero, kutembenuza, kapena kugaya.
Cerium ili ndi zingapo zomwe zingagwiritsidwe ntchito chifukwa cha mawonekedwe ake apadera. Nthawi zambiri amagwiritsidwa ntchito ngati chothandizira popanga mafuta a petulo ndi mafuta ena, komanso amagwiritsidwa ntchito popanga zoumba, magalasi, ndi zinthu zina. Amagwiritsidwanso ntchito popanga ma alloys, chifukwa amatha kusintha kukana kwa dzimbiri ndi mphamvu zazitsulo zina.
Chifukwa chakuchitanso bwino ndi okosijeni, chitsulo cha cerium nthawi zambiri chimasungidwa mumlengalenga kapena pansi pa mafuta kuti chipewe okosijeni.

Kugwiritsa ntchito

Zothandizira pakuwongolera magalimoto: Cerium amagwiritsidwa ntchito kwambiri mu otembenuza magalimoto othandizira. Zimakhala ngati chothandizira kulimbikitsa makutidwe ndi okosijeni wa carbon monoxide ndi ma hydrocarbons, komanso kuchepetsa ma nitrogen oxides (NOx) mu mpweya wotulutsa mpweya. Kuwonjezera kwa cerium kumapangitsa kuti ma converterswa azigwira bwino ntchito, kuthandizira kukwaniritsa malamulo okhwima a chilengedwe komanso kuchepetsa mpweya woipa wa magalimoto.
Kupanga magalasi ndi ceramic: Cerium oxide imachokera ku cerium yoyera ndipo imagwiritsidwa ntchito ngati chopukutira pamagalasi ndi mafakitale a ceramic. Tinthu tating'onoting'ono tating'onoting'ono timatha kupukuta pamwamba pa galasi, ndikupereka mawonekedwe apamwamba kwambiri. Kuphatikiza apo, mankhwala a cerium amagwiritsidwa ntchito kukonza mawonekedwe agalasi, monga kuyamwa kwa UV ndi kukulitsa mtundu, zomwe zimapangitsa kuti zikhale zofunikira pakupanga zinthu zapadera zamagalasi.
Alloying wothandizira: Pure cerium imagwiritsidwa ntchito ngati alloying alloying zitsulo zosiyanasiyana, makamaka popanga mischmetal yamitundu yosowa padziko lapansi. Kuphatikizika kumeneku kumapangitsa kuti zitsulo zisamawonongeke komanso kukana dzimbiri, zomwe zimapangitsa kuti zigwiritsidwe ntchito muzamlengalenga, zamagalimoto ndi mafakitale ena apamwamba kwambiri. Kuphatikiza kwa cerium kumawonjezera mphamvu ndi kulimba kwa ma alloys awa.
Kusungirako Mphamvu ndi Kutembenuka: Cerium ikufufuzidwa kuti igwiritsidwe ntchito m'makina osungira mphamvu, makamaka mabatire a redox. Kuthekera kwa Cerium kukumana ndi ma oxidation ndi kuchepetsa zomwe zimachitika kumapangitsa kuti akhale munthu wokhoza kuwongolera magwiridwe antchito komanso mphamvu zamakina osungira magetsiwa. Ntchitoyi ndiyofunikira kupititsa patsogolo matekinoloje amagetsi ongowonjezwdwanso komanso kupititsa patsogolo njira zowongolera mphamvu.
