Cerium, aha ahụ sitere n'aha Bekee nke asteroid Ceres. Ọdịnaya nke cerium n'ime eriri ụwa dị ihe dịka 0.0046%, nke bụ ụdị kachasị ukwuu n'etiti ihe ndị dị ụkọ n'ụwa. Cerium dị na monazite na bastnaesite, kamakwa na ngwaahịa fission nke uranium, thorium, na plutonium. Ọ bụ otu n'ime ebe nyocha na physics na sayensị ihe.
Dịka ozi dị, cerium enweghị ike kewaa n'ihe fọrọ nke nta ka ọ bụrụ mpaghara ngwa ụwa niile na-adịghị ahụkebe. Enwere ike ịkọwa ya dị ka "ọgaranya ma maa mma" nke ihe ndị dị n'ụwa na-adịghị ahụkebe yana " dọkịta cerium" gburugburu na ngwa.
Enwere ike iji cerium oxide mee ihe ozugbo dị ka ntụ ntụ na-egbuke egbuke, ihe mgbakwunye mmanụ, mmanụ ụgbọala, onye na-akwalite ikuku gas, wdg. silicon carbide abrasives, mmanụ ụgbọala cell akụrụngwa, ihe ndọta na-adịgide adịgide, mkpuchi, ihe ịchọ mma, roba, dị iche iche alloy steels, lasers na Ọla na-abụghị igwe, wdg.
N'ime afọ ndị na-adịbeghị anya, a na-etinye ngwaahịa cerium oxide dị ọcha na mkpuchi nke ibe na polishing nke wafers, ihe semiconductor, wdg; A na-eji cerium oxide dị elu na-adị ọcha na ihe ngosi kristal mmiri dị mkpa (LFT-LED) ọhụrụ, ihe na-egbuke egbuke, na corrosives sekit; A na-eji cerium carbonate dị ọcha na-emepụta ntụ ntụ na-egbuke egbuke dị elu maka sekit polishing, na cerium ammonium nitrate dị elu dị ka ihe na-emebi emebi maka mbadamba sekit na sterilization na nchekwa maka ihe ọṅụṅụ.
Cerium sulfide nwere ike dochie ndu, cadmium na ọla ndị ọzọ na-emerụ ahụ gburugburu na ụmụ mmadụ ma jiri ya mee ihe na pigmenti. Ọ nwere ike ịcha rọba, a pụkwara iji ya mee ihe na agba, ink, na ụlọ ọrụ akwụkwọ.
Sistemụ laser Ce:LiSAF bụ laser steeti siri ike nke United States mepụtara. Enwere ike iji ya chọpụta ngwa agha ndị na-akpata ọrịa site na nyochaa mkpokọta tryptophan, a pụkwara iji ya na ọgwụ.
Ngwa nke cerium na iko dị iche iche ma dị iche iche.
A na-agbakwunye cerium oxide na iko kwa ụbọchị, dị ka ihe owuwu ụlọ na iko ụgbọ ala, iko kristal, nke nwere ike ibelata nnyefe nke ụzarị ultraviolet, ma ejiri ya mee ihe na Japan na United States.
A na-eji cerium oxide na neodymium oxide mee ihe maka imepụta iko, na-edochi onye na-eme ihe na-acha ọcha arsenic nke omenala, nke ọ bụghị nanị na-eme ka arụmọrụ dịkwuo mma, kamakwa na-ezere mmetọ nke arsenic ọcha.
Cerium oxide bụkwa ezigbo ihe eji agba agba agba. Mgbe iko a na-ahụ anya nke nwere ihe na-acha agba agba ụwa na-adịghị ahụkebe na-amịkọrọ ìhè a na-ahụ anya nke nwere ogologo 400 ruo 700 nanometer, ọ na-enye agba mara mma. Enwere ike iji iko ndị a nwere agba mee ọkụ maka ụgbọ elu, ịnya ụgbọ ala, ụgbọ ala dị iche iche, na ihe ịchọ mma dị elu dị iche iche. Nchikota cerium oxide na titanium dioxide nwere ike ime ka iko ahụ yie odo odo.
Cerium oxide na-edochi arsenic oxide ọdịnala dị ka ihe na-eme ka iko dị mma, nke nwere ike wepu afụ wee chọpụta ihe ndị nwere agba. Ọ nwere mmetụta dị ịrịba ama na nkwadebe nke karama iko na-enweghị agba. Ngwaahịa a gwụchara nwere ọcha na-egbuke egbuke, nghọta dị mma, ike iko dị mma na nguzogide okpomọkụ, ma n'otu oge ahụ na-ewepụ mmetọ nke arsenic na gburugburu ebe obibi na iko.
Na mgbakwunye, ọ na-ewe nkeji 30-60 iji kpochaa oghere na cerium oxide polishing powder n'ime otu nkeji. Ọ bụrụ na-eji ígwè oxide polishing ntụ ntụ, ọ na-ewe 30-60 nkeji. Cerium oxide polishing ntụ ntụ nwere uru nke obere usoro onunu ogwu, ngwa ngwa polishing ọsọ na elu polishing arụmọrụ, na nwere ike ịgbanwe polishing àgwà na arụ ọrụ gburugburu ebe obibi. A na-eji ya eme ihe n'ọtụtụ ebe na polishing nke igwefoto, oghere igwefoto, tubes foto TV, anya anya ihe nkiri, wdg.
