Isici iCerium (Ce)

I-element ethi “cerium” yatholakala futhi yaqanjwa ngo-1803 ngusosayensi waseJalimane uMartin Heinrich Klaproth kanye nosokhemisi baseSweden uJöns Jakob Berzelius noWilhelm Hisinger, behlonipha i-asteroid Ceres, eyatholakala ngo-1801.

I-Cerium inezinhlobo eziningi zezicelo:
(1) Njengesengezo engilazini,i-ceriumingamunca imisebe ye-ultraviolet kanye ne-infrared, okwenza isetshenziswe kakhulu engilazini yezimoto. Lokhu akuvikeli nje kuphela emisebeni ye-ultraviolet kodwa futhi kunciphisa izinga lokushisa langaphakathi lezimoto, ngaleyo ndlela kulondolozwe amandla asetshenziselwa ukupholisa umoya. Kusukela ngo-1997, zonke izingilazi zezimoto eJapane ziye zafaka i-cerium oxide, kwathi ngo-1996, i-United States yasebenzisa amathani angaphezu kwe-1,000 e-i-cerium oxideyengilazi yezimoto.

(2)I-Ceriumokwamanje isetshenziswa kuma-catalyst okuhlanza igesi yokukhipha ugesi ezimotweni, okuvimbela ngempumelelo ukukhishwa okukhulu kwamagesi okukhipha ugesi ezimotweni emoyeni. E-United States, ukusetshenziswa kwe-cerium ngale njongo kwakha ingxenye yesithathu yokusetshenziswa komhlaba ongavamile.

(3) I-Cerium sulfide ingathatha indawo yezinsimbi eziyingozi zemvelo ezifana ne-lead kanye ne-cadmium kuma-pigment, afanelekela ukufaka imibala epulasitiki, kanye nasezimbonini zopende, uyinki kanye nephepha.

(4) Uhlelo lwe-laser lwe-Ce: LiSAF, i-laser yesimo esiqinile eyasungulwa e-United States, ingaqapha amazinga e-tryptophan ukuthola izikhali zebhayoloji futhi inezinhlelo zokusebenza zezokwelapha.

Ukuguquguquka kwe-cerium kubonakala emikhakheni eminingi, kufaka phakathi izimpushana zokupholisha, izinto zokugcina i-hydrogen, izinto ze-thermoelectric, ama-electrode e-cerium tungsten, ama-capacitor e-ceramic, ama-ceramic e-piezoelectric, ama-abrasives e-cerium silicon carbide, izinto ze-fuel cell, ama-catalyst kaphethiloli, izinto ezithile ezihlala njalo ze-magnet, izinsimbi ze-alloy ezahlukahlukene, kanye nezinsimbi ezinemibala.
