Kev Piav Qhia & Nta

Piav Qhia: WNX siv cov thev naus laus zis tsim khoom tsis siv neeg thiab siv cov khoom siv raw zoo los tsim cov khoom zooCerium Carbonate Muaj Peev Xwm Siab.

Cov Nta Tseem Ceeb:

Kev Ntshiab Siab:Cerium Carbonate Muaj Peev Xwm Siab

tsis muaj cov khoom tsis huv los ntawm cov khoom tsis tshua muaj (xws li hlau, calcium, sodium), thiab cov ntsiab lus tsis huv yog tsawg.

Kev yaj zoo:Cerium Carbonate Muaj Peev Xwm Siab

tuaj yeem yaj sai sai hauv dej thiab cov kua qaub muaj zog.

Kev sib xws: Kev tswj hwm cov khoom nruj hauv kev tsim khoomCerium Carbonate Muaj Peev Xwm Siab

ua kom ruaj khov zoo rau kev lag luam loj.

Cov tshuaj catalyst rau kev lag luam tshuaj lom neeg: cerium carbonate uas muaj cov khoom siv siab heev yog cov khoom siv tseem ceeb rau kev tsim cov tshuaj catalysts rau kev ntxuav cov pa tawm hauv tsheb. Nws tuaj yeem txhawb kev hloov pauv catalytic ntawm cov pa roj carbon monoxide, hydrocarbons, thiab nitrogen oxides, ua raws li kev hloov pauv thoob ntiaj teb ntawm kev txo qis pa phem. Nws kuj tseem siv rau hauv cov txheej txheem roj av catalytic cracking (FCC) los txhim kho kev tsim roj.

Cov tshuaj tshem tawm phosphorus rau cov pas dej: Raws li nws cov khoom siv tshuaj lom neeg, cerium carbonate tuaj yeem tshem tawm cov phosphate ntawm cov dej los ntawm kev nag lossis daus, uas yog qhov pab tau rau kev daws teeb meem ntawm cov dej hauv lub cev eutrophication.

Cov roj teeb thiab cov khoom siv zog: Cov cerium carbonate uas muaj cov khoom huv si siab siv rau hauv cov roj teeb oxide khov kho (SOFC) thiab cov thev naus laus zis khaws cia zog, ua kom cov ion conductivity thiab cov khoom ruaj khov dua los txhim kho kev ua haujlwm ntawm lub roj teeb. Nws kuj yog cov khoom siv tseem ceeb rau kev npaj cov khoom siv tseem ceeb hauv cov khoom siv khaws cia zog xws li cov roj teeb nickel-hlau hydride.

Cov tshuaj lom neeg nruab nrab: Ua ib qho tseem ceeb ua ntej, cerium carbonate uas muaj cov khoom siv siab yog siv los ua lwm cov tshuaj cerium, xws li cerium oxide thiab cerium chloride. Tsis tas li ntawd, nws ua haujlwm ua cov khoom siv raw nruab nrab rau kev tsim cov khoom siv luminescent tsis tshua muaj (siv rau hauv LEDs, cov zaub) thiab cov hmoov txhuam kom meej.
