Lub ntsiab'cerium' tau tshawb pom thiab muaj npe nyob rau hauv 1803 los ntawm German Klaus, Swedes Usbzil, thiab Hessenger, nyob rau hauv lub cim xeeb ntawm lub asteroid Ceres nrhiav tau nyob rau hauv 1801.
Kev siv ceriumtuaj yeem sau tau ntau yam hauv qab no.
(1) Cerium, raws li cov iav ntxiv, tuaj yeem nqus tau ultraviolet thiab infrared rays thiab tau siv dav hauv iav tsheb. Tsis tsuas yog nws tuaj yeem tiv thaiv hluav taws xob ultraviolet, tab sis nws tuaj yeem txo qhov kub hauv lub tsheb, yog li txuag hluav taws xob rau cua txias. Txij li xyoo 1997, cerium oxide tau ntxiv rau txhua lub iav tsheb hauv Nyiv. Xyoo 1996, tsawg kawg yog 2000 tons ntawm cerium oxide tau siv rau hauv iav tsheb, thaum nyob hauv Tebchaws Meskas, muaj txog 1000 tons ntxiv.
(2) Cerium tam sim no tau siv rau hauv tsheb purification catalysts, uas tuaj yeem tiv thaiv kom tsis txhob muaj cov pa roj ntau ntawm cov pa tawm mus rau hauv huab cua. Tebchaws Asmeskas suav rau ntau dua ib feem peb ntawm tag nrho cov khoom siv tsis tshua muaj hauv cheeb tsam no.
(3) Cerium sulfide tuaj yeem hloov cov hlau xws li txhuas thiab cadmium uas ua rau muaj kev phom sij rau ib puag ncig thiab tib neeg hauv cov xim, xim yas, thiab tuaj yeem siv rau hauv kev lag luam xws li coatings, number case, thiab ntawv. Tam sim no, lub tuam txhab ua lag luam yog Fabkis lub tuam txhab Rhone Planck.
(4) Lub Ce: Li SAF laser system yog lub zog-xeev laser tsim nyob rau hauv Tebchaws Meskas, uas tuaj yeem siv los kuaj cov riam phom lom thiab tshuaj los ntawm kev saib xyuas cov concentration ntawm tryptophan.
Cerium muaj ntau yam kev siv, nrog yuav luag txhua daim ntawv thov hauv ntiaj teb uas tsis tshua muaj muaj cerium. Xws li polishing hmoov, hydrogen cia cov ntaub ntawv, thermoelectric cov ntaub ntawv, cerium tungsten electrodes, ceramic capacitors, piezoelectric ceramics, cerium silicon carbide abrasives, roj cell raw cov ntaub ntawv, roj av catalysts, tej yam ruaj khov hlau nplaum cov ntaub ntawv, ntau yam alloy steels thiab non-ferrous hlau, thiab lwm yam .
