Igice cya Cerium (Ce)

Ikinyabutabire "cerium" cyavumbuwe cyitirirwa mu 1803 n'umuhanga mu bya siyansi w'Umudage Martin Heinrich Klaproth n'abahanga mu bya shimi bo muri Suwede Jöns Jakob Berzelius na Wilhelm Hisinger, mu rwego rwo guha icyubahiro Ceres y'ikirere, yavumbuwe mu 1801.

Cerium ifite uburyo bwinshi bwo kuyikoresha:
(1) Nk'inyongera mu kirahure,seriyamuishobora gukurura imirasire ya ultraviolet na infrared, bigatuma ikoreshwa cyane mu kirahuri cy’imodoka. Ibi ntibirinda gusa imirasire ya ultraviolet ahubwo binagabanya ubushyuhe bw’imbere mu modoka, bityo bikarinda ingufu zikoreshwa mu gukonjesha. Kuva mu 1997, ibirahuri byose by’imodoka mu Buyapani byashyizemo cerium oxyde, kandi mu 1996, Leta Zunze Ubumwe za Amerika zakoresheje toni zirenga 1.000 zaokiside ya seriyumuku birahure by'imodoka.

(2)Ceriumubu ikoreshwa mu gukamura imyuka ihumanya ikirere, ikarinda imyuka ihumanya ikirere cyane. Muri Leta Zunze Ubumwe za Amerika, ikoreshwa rya cerium muri urwo rwego rigize kimwe cya gatatu cy'ikoreshwa ry'ubutaka budasanzwe.

(3) Sulfide ya Cerium ishobora gusimbura ibyuma byangiza ibidukikije nka lead na cadmium mu mabara, akwiriye gusimburwa na pulasitiki, ndetse no mu nganda zikora amarangi, wino n'impapuro.

(4) Sisitemu ya laser ya Ce: LiSAF, laser ya state solid-state yakozwe muri Leta Zunze Ubumwe za Amerika, ishobora kugenzura ingano ya tryptophan kugira ngo imenye intwaro za biyoloji kandi ifite akamaro mu buvuzi.

Uburyo Cerium ikora buri kugaragara mu nzego nyinshi, harimo ifu yo gusya, ibikoresho byo kubika hydrogen, ibikoresho bya thermoelectric, cerium tungsten electrodes, ceramic capacitors, piezoelectric ceramics, cerium silicon carbide abrasives, lisansi ya lisansi, catalysts za lisansi, ibikoresho byihariye bya magneti bihoraho, ibyuma bitandukanye bya alloy, n'ibyuma by'amabara.
