I-Cerium iyinsimbi engavamile yomhlaba eyaziwa ngokukwazi ukuvutha ngokuzenzekelayo emoyeni, kanye nokusetshenziswa kwayo ekukhiqizeni i-cerium oxide, esetshenziswa njengenhlanganisela yokupholisha. Kuyinsimbi ethambile, esiliva-emhlophe evame ukukhiqizwa ngendlela yama-ingots noma impushana.
Amakhiyubhu ensimbi ye-cerium angakhiqizwa ngezindlela ezihlukahlukene, njengokuphonsa noma ukusika kusuka kuma-ingots amakhulu. I-cerium metal ithambile futhi ingenziwa kalula ngomshini, ngakho-ke ingabunjwa ibe yizinhlobo ezahlukahlukene ngezinqubo ezinjengokugaya, ukujika, noma ukugaya.
I-Cerium inenani lezicelo ezingase zibe khona ngenxa yezakhiwo zayo eziyingqayizivele. Ivame ukusetshenziswa njenge-catalyst ekukhiqizeni uphethiloli nezinye izinto zokubasa, futhi isetshenziselwa ukukhiqizwa kwezitsha zobumba, ingilazi, nezinye izinto. Ibuye isetshenziswe ekukhiqizeni ama-alloys, njengoba ingathuthukisa ukumelana nokugqwala namandla kwezinye izinsimbi.
Ngenxa yokuphinda isebenze komoya-mpilo, insimbi ye-cerium ivamise ukugcinwa endaweni engasebenzi noma ngaphansi kukawoyela ukuze kuvinjelwe i-oxidation.

Isicelo

Ama-Catalysts ekulawuleni ukungcola kwezimoto: I-Cerium isetshenziswa kabanzi kuma-catalytic converters ezimoto. Isebenza njenge-catalyst ukukhuthaza i-oxidation ye-carbon monoxide nama-hydrocarbons, kanye nokunciphisa i-nitrogen oxides (NOx) kumagesi okukhipha umoya. Ukwengezwa kwe-cerium kuthuthukisa ukusebenza kahle kwalezi ziguquli, kusiza ukuhlangabezana nemithetho eqinile yezemvelo kanye nokunciphisa ukungcola okuyingozi okuvela ezimotweni.
Ukukhiqizwa kwengilazi kanye ne-ceramic: I-Cerium oxide isuselwa ku-cerium emsulwa futhi isetshenziswa njenge-ejenti yokupholisha ezimbonini zengilazi neze-ceramic. Izinhlayiya zayo ezinhle zingapholisha kahle ingaphezulu lengilazi, zinikeze isiphetho sekhwalithi ephezulu. Ngaphezu kwalokho, ama-cerium compounds asetshenziselwa ukuthuthukisa izakhiwo ze-optical zengilazi, njengokumuncwa kwe-UV nokuthuthukisa umbala, okwenza kube yigugu ekukhiqizeni imikhiqizo yengilazi ekhethekile.
I-ejenti ye-alloying: I-cerium ehlanzekile isetshenziswa njenge-alloying ejenti yezinsimbi ezihlukahlukene, ikakhulukazi ekukhiqizeni i-mischmetal yensimbi engavamile yomhlaba. Le ngxubevange ithuthukisa izakhiwo zemishini kanye nokumelana nokugqwala kwensimbi, ikwenze ifanelekele ukusetshenziswa endaweni yezindiza, ezezimoto kanye nezinye izimboni ezisebenza kahle kakhulu. Ukwengezwa kwe-cerium kwandisa amandla nokuqina kwalawa ma-alloys.
Isitoreji Amandla Nokuguqulwa: I-Cerium iyahlolwa ukuze isetshenziswe ezinhlelweni zokugcina amandla, ikakhulukazi amabhethri agelezayo e-redox. Ikhono le-Cerium lokuthola kokubili ukusabela kwe-oxidation kanye nokunciphisa kuyenza ibe yikhandidethi elinamandla lokuthuthukisa ukusebenza kahle namandla alezi zinhlelo zokugcina amandla. Lolu hlelo lokusebenza lubalulekile ekuthuthukiseni ubuchwepheshe bamandla avuselelekayo kanye nokuthuthukisa izixazululo zokuphatha amandla.
