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 uas tsis muaj Chloride ntau.

Cov Nta Tseem Ceeb:

Kev Ntshiab Siab:Cerium Carbonate uas tsis muaj Chloride ntau 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 uas tsis muaj Chloride ntau 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 uas tsis muaj Chloride ntau ua kom ruaj khov zoo rau kev lag luam loj.

Cov Tshuaj thiab Cov Tshuaj Reagents: Cov ntsiab lus tsis huv ntawm cov cerium carbonate uas muaj cov tshuaj chlorine tsawg heev, thiab nws cov tshuaj ntshiab yog siab heev. Nws yog qhov tsim nyog heev rau kev siv ua cov tshuaj nruab nrab thiab cov tshuaj reagent ntshiab, tshwj xeeb tshaj yog hauv kev tshawb fawb biochemical thiab tshuaj uas xav tau cov khoom siv cerium ntshiab siab.

Kev tsim cov catalyst zoo tshaj plaws: Vim nws cov chloride ion tsawg heev, nws tuaj yeem tiv thaiv kev lom catalyst. Nws yog cov khoom siv zoo tshaj plaws rau kev tsim cov catalysts peb txoj kev ntxuav pa tawm hauv tsheb thiab cov catalysts fluid catalytic cracking (FCC) siv hauv petrochemicals.

Cov Khoom Siv Hluav Taws Xob thiab Cov Khoom Siv Ua Haujlwm: Cov khoom siv chlorine qis ntawm cov ntaub ntawv no ua rau lawv muaj txiaj ntsig zoo hauv kev tsim cov khoom siv hluav taws xob (xws li cov khoom siv ceramic capacitors MLCC), cov khoom siv luminescent tsis tshua muaj neeg pom, thiab cov khoom siv hlau nplaum nyuaj, ua rau kev ua haujlwm rwb thaiv tsev thiab kev ntseeg siab ntawm cov khoom kawg zoo dua.

Kev kho dej thiab kev tshem tawm phosphorus: Vim nws cov khoom siv tshuaj lom neeg, cerium carbonate tuaj yeem tshem tawm phosphate ntawm cov dej los ntawm kev nag. Cov mis tshuaj chlorine qis zam kev ua qias tuaj ntawm chloride thib ob thiab muab kev daws teeb meem zoo dua rau ib puag ncig rau qhov teeb meem ntawm dej eutrophication.
