UmrintshiInsimbi engwevu nenempilo enobude be-6.9G / CM3 (Crystal Crystal), i-6.7G / CM3 (i-hexagonal crystal), iphuzu elincibilikayo le-7 943 ℃, ne-dectice. Yinsimbi ye-lanthanide yemvelo ngokwemvelo ngokwemvelo. Imichilo ye-carium ebekiwe ivame ukunqwabelana.
UmrintshiI-oxid kalula emazingeni okushisa asekamelweni bese ilahlekelwa yi-luster yayo emoyeni. Ingashiswa emoyeni ngokusola ngommese (cerium omsulwa akuthambekele ekujuleni kokuziqhenya, kepha kuthambekele kakhulu ekushayweni kokuzenzakalelayo lapho i-oxidized kancane noma igcotshwe ngensimbi). Lapho kufuthelwa, kuvutha emoyeni ukukhiqiza uCheria. Ungasabela ngamanzi abilayo ukukhiqiza i-cellium hydroxide, incibilika ku-acid kepha insoluble e-Alkali.
1, imfihlakalo yento ye-cerium
Isisiko,ngenombolo ye-athomu engu-58, ingeyeizinto zomhlaba ezingavamileFuthi yinto ye-lanthanide eqenjini leQembu lesithupha. Uphawu lwayo lokuqalaCe, futhi kuyinsimbi yesiliva elisebenzayo. I-powder yayo ithambekele ekujuleni kokuziqhenya emoyeni futhi incibilika kalula kuma-acid kanye nama-ejenti. Igama elithi Cresium livela eqinisweni lokuthi okuqukethwe kwe-certium ekuqothulweni komhlaba kucishe kube ngu-0,0046%, okwenza kube yinto ebanzi kakhulu yomhlaba engavamile
Emhlabeni onqabile womndeni, ngokungangabazeki u-ORTION ngokungangabazeki "umfowethu omkhulu". Okokuqala, ubuningi bomhlaba ongandile ekuqothulweni komhlaba bungu-238 ppm, nge-accounting ye-cerium engu-68 ppm, okungu-28% wokusatshalaliswa komhlaba okuphelele komhlaba kanye nezindawo zokuqala; Okwesibili, i-cereyusi kwakuyinto yesibili emhlaba wonke ethola iminyaka eyisishiyagalolunye ngemuva kokutholwa kweytttriumngo-1794. Njengamanje, imininingwane efanelekile ibuyekeziwe, ungabheka iwebhusayithi yolwaziIzindaba zebhizinisi.
2, ukusetshenziswa okuyinhloko kwe-cerium
1. Izinto ezinobungane bemvelo, ngohlelo lokusebenza olumele kakhulu ukuba yi-catalysts yokuhlanza izimoto ezihlanjululweni. Ukungezwa kwe-certium ku-catalysts evame ukusetshenziswa kwezinsimbi eziyigugu njengeplatinamu, i-rhodium, i-palladium, njll. Kungathuthukisa ukusebenza kwe-catalyst futhi kunciphise inani lezinsimbi eziyigugu ezisetshenzisiwe. Ukungcola okuyinhloko kumagesi okuphelelwa yi-carbon monoxide, ama-hydrocarbons, kanye ne-ammonia oxides, okungathinta i-hematopogeic system, futhi kukhiqize ama-carcinogens, akhiqize ama-carcinogen, adale ukulimala kwabantu, izilwane nezitshalo. Ubuchwepheshe be-tererrary hlazo bungakwazi ngokuphelele i-hydrocarbons ne-carbon monoxide ukukhiqiza ikhabhoni namanzi, futhi babola oxides e-ammonia nomoya-mpilo (yingakho igama elithi ternary catalysis).
2. Ukufakwa kwezinsimbi ezilimazayo Ingasetshenziswa futhi ezimbonini ezinjengezimbali, inks, nephepha. Ama-Organic ahlanganisiwe anjengeCerium Rich Light Rate Rre Endrh emhlabeni usawoti we-cyclic acid usawoti futhi asetshenziswa njengama-ejenti wokupenda, ama-pvc plastice stivilizer, kanye ne-MC Nylon Modifiers. Bangathatha indawo yezinto ezinobuthi ezifana nosawoti wokuhola futhi banciphise izinto ezibizayo ezifana nosawoti wokumba. 3 Isetshenziswa njengesengezo sokuphakelayo, ingakhuphula izinga lokukhiqizwa kwamaqanda lezinkukhu kanye nezinga lokusinda kwezinhlanzi kanye nokulima kwe-shrimp, futhi kuthuthukisa nekhwalithi yoboya yezimvu ezinde ezinezinwele.
3, amakhompiyutha ajwayelekile we-certium
1.I-Cerrium Oxide- into engaphansi kwefomula yamakhemikhaliI-CEO2, i-powder ekhanyayo ekhanyayo noma ephuzi. I-Density 7.13G / CM3, I-Seling Point 2397 ℃, insoluble emanzini nase-Alkali, incane kancane ku-acid. Ukusebenza kwayo kufaka phakathi izinto zokupholisa, ama-catalysts, abathwali be-catalyst (izengezo), ama-ultraviolet atholakalayo, ama-electrotive cell electroly, ama-ceramics aphethwe yi-elektroniki, njll.
2 Ungowomabala wokuhlanza ama-inorganic, unamandla okufaka imibala, umbala okhanyayo, ukumelana nokushisa okuhle, ukumelana nokukhanya, ukumelana okuhle, futhi kuyinto ebambekayo yokungenisa, futhi ikhona indawo enhle yokungenisa imibala ethe xaxa ye-cadmium ebomvu.
3. Cerium chloride- Yaziwa nangokuthi i-CERTIUM Trichloride, iyi-anhydrouscerium chlorideNoma i-complect ye-cerdrate of cerrium chloride ecasulayo amehlo, uhlelo lokuphefumula kanye nesikhumba. Isetshenziswa ezimbonini ezinjenge-petroleum catalysts, ama-catalysts ezithuthi izimoto, amakhompiyutha aphakathi nendawo, futhi nasekukhiqizweni kweI-Cerium Metal.
