I-Cerium yintsimbi enqabileyo yomhlaba eyaziwayo ngokukwazi ukuvutha ngokuzenzekelayo emoyeni, kunye nokusetyenziswa kwayo kwimveliso ye-cerium oxide, esetyenziswa njenge-polish compound. Yintsimbi ethambileyo, emhlophe-emhlophe ehlala iveliswa ngohlobo lweengots okanye umgubo.
Iityhubhu zetsimbi ye-cerium zinokuveliswa ngeendlela ezahlukeneyo, ezifana nokuphosa okanye ukusika kwiingots ezinkulu. Isinyithi seCerium sithambile kwaye sinomatshini ngokulula, ngoko sinokubunjwa kwiifom ezahlukeneyo ngokusebenzisa iinkqubo ezifana nokusila, ukujika, okanye ukugaya.
I-Cerium inenani lezicelo ezinokubakho ngenxa yeempawu zayo ezizodwa. Ihlala isetyenziswa njenge-catalyst kwimveliso yepetroli kunye namanye amafutha, kwaye isetyenziselwa ukuveliswa kweekeramics, iglasi kunye nezinye izinto. Ikwasetyenziselwa ukuveliswa kwee-alloys, njengoko inokuphucula ukuxhathisa i-corrosion kunye namandla kwezinye izinyithi.
Ngenxa yokuphinda isebenze ngeoksijini, isinyithi secerium sigcinwa kwindawo engasebenziyo okanye phantsi kweoyile ukunqanda i-oxidation.

Isicelo

IiCatalysts kulawulo lokukhutshwa kweemoto: I-Cerium isetyenziswa ngokubanzi kwii-automotive catalytic converters. Isebenza njenge-catalyst yokukhuthaza i-oxidation ye-carbon monoxide kunye ne-hydrocarbons, kunye nokunciphisa i-nitrogen oxides (NOx) kwiigesi zokukhupha. Ukongezwa kwe-cerium kuphucula ukusebenza kakuhle kwaba baguquli, kunceda ukuhlangabezana nemimiselo engqongqo yokusingqongileyo kunye nokunciphisa ukukhutshwa okuyingozi kwizithuthi.
Iglasi kunye nemveliso ye-ceramic: I-Cerium oxide ivela kwi-cerium ecocekileyo kwaye isetyenziswe njenge-ejenti yokupholisa kwiiglasi kunye namashishini e-ceramic. Iincinci zayo ezintle zinokuthi zifake ngokufanelekileyo ubuso beglasi, zibonelela ngokugqitywa komgangatho ophezulu. Ukongeza, iikhompawundi ze-cerium zisetyenziselwa ukuphucula iimpawu zeglasi, ezifana nokufunxa kwe-UV kunye nokuphucula umbala, okwenza kube luncedo ekuveliseni iimveliso zeglasi ezikhethekileyo.
I-arhente yokudibanisa: I-cerium ecocekileyo isetyenziswa njenge-agent alloying yeentsimbi ezahlukeneyo, ngakumbi kwimveliso ye-mischmetal yensimbi enqabileyo yomhlaba. Le ngxubevange iphucula iipropati zomatshini kunye nokuxhathisa ukubola kwesinyithi, okwenza kube yinto efanelekileyo yokusetyenziswa kwi-aerospace, i-automotive kunye namanye amashishini aphezulu. Ukongezwa kwe-cerium kwandisa amandla kunye nokuqina kwezi alloys.
Ukugcinwa kwamandla kunye nokuguqulwa: I-Cerium iphononongwa ukuze isetyenziswe kwiinkqubo zokugcina amandla, ngakumbi iibhetri zokuhamba kwe-redox. Ikhono le-Cerium lokufumana zombini i-oxidation kunye nokunciphisa ukuphendula kwenza ukuba ibe ngumgqatswa onokubakho wokuphucula ukusebenza kakuhle kunye nomthamo wezi nkqubo zokugcina amandla. Esi sicelo sibalulekile ekuqhubeleni phambili iteknoloji yamandla ahlaziyekayo kunye nokuphucula izisombululo zolawulo lwamandla.
