Cerium, dzina limachokera ku dzina la Chingerezi la asteroid Ceres. Zomwe zili mu cerium mu kutumphuka kwa dziko lapansi ndi pafupifupi 0.0046%, yomwe ndi mitundu yochuluka kwambiri pakati pa zinthu zapadziko lapansi. Cerium imapezeka makamaka mu monazite ndi bastnaesite, komanso muzinthu za fission za uranium, thorium, ndi plutonium. Ndi imodzi mwamalo opezeka kwambiri pa kafukufuku wa sayansi ya zinthu ndi zinthu.
Malinga ndi zomwe zilipo, cerium ndi yosasiyanitsidwa pafupifupi pafupifupi magawo onse osowa padziko lapansi. Itha kufotokozedwa kuti ndi "wolemera komanso wokongola" wazinthu zosawerengeka padziko lapansi komanso "dotolo wa cerium" wozungulira.
Cerium okusayidi angagwiritsidwe ntchito mwachindunji monga kupukuta ufa, zowonjezera mafuta, chothandizira mafuta, utsi mpweya purifier wolimbikitsa, etc. Angagwiritsidwenso ntchito ngati chigawo chimodzi mu zinthu zosungira wa haidrojeni, zipangizo thermoelectric, cerium tungsten maelekitirodi, ceramic capacitors, piezoelectric ceramics, cerium. silicon carbide abrasives, mafuta cell zopangira, okhazikika maginito zipangizo, zokutira, zodzoladzola, mphira, zitsulo zosiyanasiyana aloyi, lasers ndi Non-ferrous zitsulo, etc.
M'zaka zaposachedwa, mankhwala oyeretsedwa kwambiri a cerium oxide akhala akugwiritsidwa ntchito pa zokutira za tchipisi ndi kupukuta kwazitsulo, zipangizo za semiconductor, ndi zina zotero; high-purity cerium oxide imagwiritsidwa ntchito muzowonjezera zatsopano za film liquid crystal display (LFT-LED), ma polishing agents, ndi corrosives circuit; high chiyero Cerium carbonate ntchito kupanga mkulu-chiyero kupukuta ufa kwa mabwalo kupukuta, ndi mkulu-chiyero cerium ammonium nitrate ntchito ngati wothandizira dzimbiri matabwa dera ndi yotsekereza ndi zosungira zakumwa.
Cerium sulfide imatha kulowa m'malo mwa lead, cadmium ndi zitsulo zina zomwe zimawononga chilengedwe komanso anthu ndipo zimagwiritsidwa ntchito popanga utoto. Imatha kukongoletsa mapulasitiki ndi utoto ndipo ingagwiritsidwenso ntchito popanga utoto, inki, ndi mafakitale a mapepala.
Ce:LiSAF laser system ndi laser yokhazikika yopangidwa ndi United States. Itha kugwiritsidwa ntchito pozindikira zida zamankhwala poyang'anira kuchuluka kwa tryptophan, ndipo itha kugwiritsidwanso ntchito ngati mankhwala.
Kugwiritsa ntchito cerium pagalasi ndi kosiyanasiyana komanso kosiyanasiyana.
Cerium oxide imawonjezeredwa ku galasi la tsiku ndi tsiku, monga galasi la zomangamanga ndi magalimoto, galasi la crystal, lomwe lingathe kuchepetsa kufalikira kwa kuwala kwa ultraviolet, ndipo lakhala likugwiritsidwa ntchito kwambiri ku Japan ndi United States.
Cerium oxide ndi neodymium oxide amagwiritsidwa ntchito pochotsa magalasi, m'malo mwachikhalidwe choyera cha arsenic decolorizing, chomwe sichimangowonjezera mphamvu, komanso chimapewa kuipitsidwa kwa arsenic oyera.
Cerium oxide ndi yabwino kwambiri yopangira utoto wagalasi. Galasi yowoneka bwino yokhala ndi utoto wosowa padziko lapansi imatenga kuwala kowoneka bwino ndi kutalika kwa ma nanometer 400 mpaka 700, imakhala ndi mtundu wokongola. Magalasi achikudawa atha kugwiritsidwa ntchito kupanga magetsi oyendetsa ndege, kuyenda, magalimoto osiyanasiyana, komanso zokongoletsera zaluso zapamwamba. Kuphatikiza kwa cerium oxide ndi titanium dioxide kungapangitse galasi kuwoneka lachikasu.
Cerium oxide imalowa m'malo mwa arsenic oxide ngati chopangira magalasi, chomwe chimatha kuchotsa thovu ndi kufufuza zinthu zamitundu. Zimakhudza kwambiri pokonzekera mabotolo agalasi opanda mtundu. Chotsirizidwacho chimakhala ndi zoyera zoyera, zowonekera bwino, zowonjezera mphamvu za galasi ndi kukana kutentha, ndipo nthawi yomweyo zimachotsa Kuwonongeka kwa arsenic ku chilengedwe ndi galasi.
Kuphatikiza apo, zimatengera mphindi 30-60 kupukuta mandala ndi cerium oxide kupukuta ufa mu mphindi imodzi. Ngati mukugwiritsa ntchito iron oxide polishing powder, zimatenga mphindi 30-60. Cerium oxide kupukuta ufa ali ndi ubwino wa mlingo waung'ono, mofulumira kupukuta liwiro ndi mkulu kupukuta bwino, ndipo akhoza kusintha kupukuta khalidwe ndi malo ntchito. Amagwiritsidwa ntchito kwambiri pakupukuta makamera, magalasi a kamera, machubu azithunzi za TV, magalasi owonera, ndi zina zambiri.
