Tsis tshua muaj ntiaj teb cerium hlau

Lub cim lub cim ntawm Cerium yog CE, nrog ib tus lej atomic naj npawb ntawm 58. Nws zwm rau hauv txoj kev lag luam hauv xovtooj thiab tseem muaj ib qho ntawm lub ntiaj teb tsawg. Cov ntsiab lus hauv lub ntiaj teb crust yog hais txog 0. 0046%, uas yog cov xim tsis muaj xws li cov hlau grey rau nyiaj thaum dawb huv. Nws yog cov nquag siv thiab yooj yim loses nws cov lus hauv huab cua. Nws cov hmoov yog yooj yim mus hlawv hauv huab cua thiab feem ntau khaws cia rau hauv lub tshuab nqus tsev lossis kua roj. Nws yog soluble hauv acid, insoluble hauv alkali, thiab tuaj yeem hnov ​​cov dej npau npau kom tsim cerium hydroxide. Cerium tshwm sim hauv ob lub peev xwm, CE (III) thiab CE (IV), thiab tetravalent oxident oxidation xeev yog ruaj khov.

Thoob ntiaj teb, lub teeb tsis tshua muaj cov hlau yog feem ntau npaj los ntawm molten ntsev electrolysis los ntawm cov av hauv ntiaj teb tsawg. Cov txheej txheem sib xyaw ua ke tau muab faib ua ob qho txheej txheem: chloride thiab oxide molten ntsev electrolysis. Chloride Molten ntsev electrolysis siv cecl₂ ua cov khoom siv raw, thiab KCl yog teeb tsa nrog Electrolyte hauv kev faib tawm. Nws tau melted thiab electrolyzed nyob rau hauv ib graphite crucite tank kom tau xim cerium, tab sis cov tshuaj chlorine, tab sis cov tshuaj chlorine tsim tawm thaum lub txheej txheem ntau lawm. Oxide Molten ntsev electrolysis siv kab hluav taws xob, thiab ua kom zoo nkauj rau hauv cov tshuaj eleveles, thiab melted thiab tank crucite Crucite Crucite Tank. Cov txheej txheem no muaj kev ua tau zoo tam sim no thiab tsis tsim cov roj roj roj lom. Nws yog cov qauv zoo tshaj plaws rau kev tsim lub teeb tsis tshua muaj hlau hauv ntiaj teb.

Catalyst teb:

Nws yog ib qho tseem ceeb ntawm cov tsheb ua kom zoo nkauj catalysts, thiab tuaj yeem txo cov pa roj carbon monome, thiab tuaj yeem txo cov pa roj carbon monides thiab hydrocarbons hauv kev tso pa tawm hauv tsheb. Nws kuj yog siv nyob rau hauv cov roj av me ntsis catalysts, xws li Zeolites impregnated nrog cerium impregnated nrog cerium thiab lanthhanum tuaj yeem siv ua roj av tawg hauv cov txheej txheem kho kom zoo nkauj.

Iav Kev Lag Luam:

Nws tuaj yeem nqus cov ultraviolet rays thiab yog siv los ua lag luam kho qhov muag iav, phosphlors rau TV thiab cov tsom iav, thiab iav kawg. Nws tuaj yeem ua kom lub durability thiab xim ua tau zoo ntawm iav thiab txhim kho cov ultraviolet tsis kam ntawm iav. Nws kuj tseem siv tau ua lub khob decolorizer, councant thiab meej li cine oxide thiab neodymium oxide rau iav decolorization. Creium oxide hloov cov tsoos oxide ua ib khob oxide uas yog lub khob pom meej kom tshem cov npuas thiab cov kab muaj xim zoo nkauj. Ntxiv rau, cerium oxide cov hmoov yog dav siv rau polishing cov koob yees duab thiab cov koob yees duab lub ntsej muag.

Kev Lag Luam Hluav Taws Xob:

Tsis tshua muaj ntiaj teb cov hlau sib txuas yog cov cuab yeej siv hluav taws xob, kev kho mob aleret (YAG)

Lwm yam:

Cerium sulfide tuaj yeem hloov cov hmoov txhuas zoo li cov hmoov txhuas thiab cadmium ua cov xim liab rau kev lag luam xws li cov tshuaj pleev xim, inks thiab ntawv. Lub ntiaj teb tsis tshua muaj cerium tuaj yeem txhim kho cov qoob loo zoo, nce qoob loo thiab txhim kho cov kev ntxhov siab tsis kam ua cov nroj tsuag kev loj hlob. Raws li pub noj ntxiv, nws tuaj yeem nce lub qe ntau lawm ntawm nqaij qaib thiab kev muaj sia nyob ntawm cov ntses thiab certiv.
