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 zoo Cerium Carbonate.

Cov Nta Tseem Ceeb:

Kev Ntshiab Siab:Cerium Carbonate 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 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 ua kom ruaj khov zoo rau kev lag luam loj.

Cov tshuaj catalysts hauv kev lag luam tshuaj lom neeg: Cerium carbonate yog ib qho tseem ceeb rau cov tshuaj catalysts uas siv rau hauv cov roj av, ua kom muaj kev hloov pauv ntawm cov roj hydrocarbon thiab tiv taus cov tshuaj sulfur. Nws kuj yog ib qho tseem ceeb ntawm cov tshuaj catalysts uas ntxuav cov pa tawm hauv tsheb, txo cov nitrogen oxides (NOx) thiab cov roj hydrocarbons los ntawm kev ua kom cov khoom khaws cia oxygen ruaj khov.

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: Cerium carbonate, ua ib qho tseem ceeb ntawm cov khoom siv tsis tshua muaj av, ua lub luag haujlwm hauv cov khoom siv cathode ntawm cov roj teeb nickel-hlau hydride (NiMH), muab kev ruaj khov zoo heev. Nws kuj yog ib qho ntawm cov khoom siv raw tseem ceeb rau kev npaj cov roj teeb oxide khov kho (SOFC) thiab cov roj teeb khaws cia zog.

Cov tshuaj synthesis intermediates: Cerium carbonate yog ib qho khoom siv tseem ceeb rau kev tsim lwm cov cerium compounds (xws li cerium chloride, cerium oxide) thiab cov khoom siv luminescent tsis tshua muaj.
