Cerium, element 58 ye tafura yemapato.
Ceriumndiyo yakanyanya kuwanda pasimbi yepasi, uye pamwe chete neiyo yakambowanikwa yeYttrium element, inovhura musuwo wekuwanikwa kweimwerare pasizvinhu.
Muna 1803, musayendisiti wechiGerman Panguva imwecheteyo, vechiSweden kuti Bizilaus uye anperter akawanawo nzombe yechinhu chakafanana mu ore. Kusvika 1875, vanhu vakawana simbi yesimbi kubva yakanyungudika cerium carides neyemagetsi.
Simbi yesimbiinoshanda kwazvo uye inogona kupisa kuti igadzire iyo poda the cerium oxide. Cerium Iron Alloy yakasanganiswa nezvimwe zvinhu zvisingawanzogona kuburitsa tsvina yakanaka kana ichipokana nezvinhu zvakaoma, nekukasira kutenderedza, uye zvinhu zvakakosha mumidziyo ine magetsi uye spark plugs. Zvichazvipisawo, unoperekedzwa neyekunyepedzera spark, simbi yakawedzerwa uye imwe lanthanide, kungoisimudzira mhedzisiro yeaya matsva. A mesh yakagadzirwa necerium kana kusungwa nemaronda anokwanisa kuwedzera kugona kwehunhu hwemafuta uye uve wakanaka kwazvo wekuzivisa rubatsiro, izvo zvinogona kuchengetedza mafuta. Cerium iri zvakare yakanaka girazi inowedzera, iyo inogona kutora ultraviolet uye infrared marangi, uye inoshandiswa zvakanyanya mugirazi remotokari. Izvo hazvingangodaro uchingotidzivirira ultraviolet riys, asi zvakare kuderedza tembiricha mumotokari, kuchengetedza magetsi emhepo.
Zvizhinji zvekushandisa zvechibvumirano zvakavakirwa pakutendeuka pakati peiyo trival cerium uye tetravallent carium, iyo ine yakasarudzika nzvimbo mune zvisingawanzo nyika simbi. Iyi ficha inobvumira cerium yekuchengeta zvinobudirira uye inoburitsa oksijeni, iyo inogona kushandiswa mumhando yakasimba oxide colecer celle detex, nokudaro kuwana iyo nzira yekufambisa yemagetsi kuti iite zvazvino. Zeolies isingabvumirwe ne cerium uye lanthanum inogona kushandira secaltsts ye petroleum kupaza panguva yekunatsa. Iko kushandiswa kweCerium oxide uye simbi dzinokosha mu autootive ternary Catalytic Converters cancers Nekuda kwekugona kwayo kutora okisijeni, vanhu vari kuongororawo maitiro ekushandisa cerium oxide naneoxidant kurapwa. Iyo yakasimba nyika Laser system yakagadzirwa neUnited States ine cerium, iyo inogona kushandiswa kuona zvombo zvebhaibheri nekutarisa kusunganidzwa kweTryptophan, uye inogona zvakare kushandiswa pakuonekwa kwekurapa.
Nekuda kweiyo yakasarudzika mafoto ephirafiti, cerium iri zvakare yakanyanya kukosha yetailst, iyo inoita yakachipaCerium (iv) oxideinofarirwa nemasayendisiti mumunda weCatalySts. Musi waChikunguru 27, 2018, Science Magazini yakaburitsa chikamu chikuru chesainzi yekutsvaga neZuwe Ziwedi kubva pachikoro cheSainzi Science Science uye tekinoroji yeShanghaitech University - inosimudzira kutendeuka kwenyunivhesiti. Iyo kiyi iri muchirongwa chekushandura ndechekutsvaga yakachipa uye inoshanda synerylsis system yeCeil Serveni, inopa basa rekutendeuka kweMethene mune yakakwirira kukosha-yakawedzerwa zvigadzirwa, senge rocket propelant mafuta.
