Chinthu cha Cerium (Ce)

Chinthu chotchedwa "cerium" chinapezeka ndipo chinatchedwa dzina mu 1803 ndi wasayansi waku Germany Martin Heinrich Klaproth ndi akatswiri a zamankhwala aku Sweden Jöns Jakob Berzelius ndi Wilhelm Hisinger, polemekeza asteroid Ceres, yomwe inapezeka mu 1801.

Cerium ili ndi ntchito zosiyanasiyana:
(1) Monga chowonjezera mu galasi,ceriumimatha kuyamwa kuwala kwa ultraviolet ndi infrared, zomwe zimapangitsa kuti igwiritsidwe ntchito kwambiri mugalasi yamagalimoto. Izi sizimangoteteza ku kuwala kwa ultraviolet komanso zimachepetsa kutentha kwamkati mwa magalimoto, motero zimasunga mphamvu zomwe zimagwiritsidwa ntchito pokonza mpweya wabwino. Kuyambira mu 1997, magalasi onse amagalimoto ku Japan akhala akugwiritsa ntchito cerium oxide, ndipo mu 1996, United States idagwiritsa ntchito matani opitilira 1,000 acerium oxidemagalasi a magalimoto.

(2)Ceriumpakadali pano imagwiritsidwa ntchito mu zotsukira mpweya wotulutsa utsi wa magalimoto, zomwe zimathandiza kupewa kutulutsa mpweya wotulutsa utsi wa magalimoto mumlengalenga. Ku United States, kugwiritsa ntchito cerium pachifukwa ichi ndi gawo limodzi mwa magawo atatu a zinthu zonse zomwe zimagwiritsidwa ntchito ndi rare earth.

(3) Cerium sulfide ikhoza kulowa m'malo mwa zitsulo zoopsa zachilengedwe monga lead ndi cadmium mu utoto, zoyenera utoto wa pulasitiki, komanso m'mafakitale opaka utoto, inki, ndi mapepala.

(4) Dongosolo la laser la Ce: LiSAF, laser yolimba yomwe idapangidwa ku United States, imatha kuyang'anira kuchuluka kwa tryptophan kuti izindikire zida zamoyo ndipo imagwira ntchito zachipatala.

Kusinthasintha kwa cerium kumawonekera m'magawo ambiri, kuphatikizapo ufa wopukuta, zinthu zosungiramo haidrojeni, zinthu zotenthetsera, ma electrode a cerium tungsten, ma capacitor a ceramic, ma piezoelectric ceramics, ma abrasives a cerium silicon carbide, zinthu zama cell amafuta, ma catalyst a petrol, zinthu zapadera zamaginito okhazikika, zitsulo zosiyanasiyana za alloy, ndi zitsulo zamitundu.
