The element'cerium' yakawanikwa uye yakatumidzwa muna 1803 naGerman Klaus, Swedes Usbzil, uye Hessenger, mukurangarira asteroid Ceres yakawanikwa muna 1801.
Kushandiswa kweceriuminogona kunyanya kupfupikiswa muzvikamu zvinotevera.
(1) Cerium, sekuwedzera kwegirazi, inogona kutora ultraviolet uye infrared mwaranzi uye yakashandiswa zvakanyanya mumotokari girazi. Haisi chete inogona kudzivirira ultraviolet mwaranzi, asi inogona zvakare kuderedza tembiricha mukati memotokari, nekudaro kuchengetedza magetsi emhepo yekufemesa. Kubva 1997, cerium oxide yakawedzerwa kune ese emota girazi muJapan. Muna 1996, anenge matani 2000 ecerium oxide akashandiswa mugirazi remotokari, nepo muUnited States, anenge matani 1000 akawedzerwa.
(2) Cerium parizvino iri kushandiswa kumotokari exhaust purification catalysts, iyo inogona kudzivirira zvinobudirira huwandu hukuru hwemotokari yekuburitsa gasi kubva pakuburitswa mumhepo. IUnited States inotora chikamu chinopfuura chikamu chimwe muzvitatu chekudyiwa kwepasi risingawanzoitiki munzvimbo iyi.
(3) Cerium sulfide inogona kutsiva simbi dzakadai somutobvu uye cadmium zvinokuvadza nharaunda uye vanhu mu pigment, mapurasitiki eruvara, uye anogonawo kushandiswa mumaindasitiri akaita semapeji, inki, uye mapepa. Parizvino, kambani inotungamira ikambani yeFrance Rhone Planck.
(4) Iyo Ce: Li SAF laser system ndeye yakasimba-state laser yakagadzirwa muUnited States, inogona kushandiswa kuona zvombo zvebhaibheri uye mushonga nekutarisa kuunganidzwa kwe tryptophan.
Cerium ine huwandu hwakawanda hwemashandisirwo, ine dzinenge dzese dzisingawanzo pasi maapplication ane cerium. Zvakadai sehupfu hwekupukuta, hydrogen yekuchengetera zvinhu, thermoelectric zvinhu, cerium tungsten electrodes, ceramic capacitors, piezoelectric ceramics, cerium silicon carbide abrasives, mafuta cell raw materials, peturu catalysts, zvimwe zvisingaperi magineti zvinhu, akasiyana alloy simbi uye asiri-ferrous simbi, nezvimwe, nezvimwe. .
