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 Fluoride.

Cov Nta Tseem Ceeb:

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

Cov tshuaj catalyst hauv kev lag luam tshuaj lom neeg: Cerium tetrafluoride (CeF)₄) yog ib tug neeg sawv cev oxidizing muaj zog thiab siv ua tus catalyst hauv ntau yam kev tshuaj tiv thaiv hauv cov organic synthesis, xws li kev xaiv oxidation ntawm cov cawv rau ketones thiab kev ncaj qha sulfonation ntawm methane nrog sulfur trioxide los tsim methanesulfonic acid. Nws cov khoom oxidizing yog qhov tseem ceeb tshwj xeeb hauv qab cov xwm txheej acidic thiab tuaj yeem siv ua ib qho kev ua haujlwm zoo ib leeg-electron oxidant. Cerium trifluoride (CeF₃) yog siv los ua cov khoom siv catalyst hauv roj av catalytic cracking (FCC) los txhim kho kev hloov pauv ntawm cov hydrocarbons.

Cov Iav Tshwj Xeeb thiab Cov Khoom Siv Kho Qhov Muag: Cerium trifluoride (CeF₃) yog cov khoom siv tseem ceeb rau kev tsim cov iav kho qhov muag precision, uas tuaj yeem txhim kho qhov kev ua tau zoo ntawm kev nqus ultraviolet ntawm cov iav thiab siv ua hmoov txhuam iav thiab desensitizer. Cerium tetrafluoride (CeF₄) siv rau hauv kev txheej txheem kho qhov muag, muab kev ua tau zoo tiv thaiv kev cuam tshuam rau cov iav thiab daim iav, txhim kho kev ruaj khov thiab kev ua tau zoo ntawm cov khoom siv kho qhov muag. Ob qho tib si yog siv ua cov ntaub ntawv scintillator hauv kev sim physics muaj zog siab thiab cov teb kuaj pom hluav taws xob.

Cov roj teeb thiab cov khoom siv zog: Cerium trifluoride (CeF₃) yog siv ua cov khoom siv sulfur hauv cov roj teeb lithium-sulfur. Nws cov qauv nanocage tshwj xeeb (h-CeF₃) tuaj yeem txhim kho kev ua haujlwm ntawm lub roj teeb los ntawm kev sib koom ua ke ntawm kev kaw lub cev thiab kev nqus tshuaj lom neeg. Tetrafluorocerium (CeF₄) yog ib yam khoom siv rau cov fluoride ion conductors thiab siv tau los tsim cov roj teeb fluoride ion solid-state, uas muaj peev xwm ua kom muaj zog ntau dua. Cerium trifluoride kuj tseem tab tom kawm ua cov khoom siv electrolyte rau cov roj teeb oxide solid (SOFC).

Cov tshuaj lom neeg nruab nrab: Cerium trifluoride thiab cerium tetrafluoride yog ob qho tseem ceeb precursors rau synthesizing lwm cov cerium compounds. Cerium trifluoride yog cov khoom siv raw rau kev npaj cov hlau cerium, thaum cerium tetrafluoride tuaj yeem tsim los ntawm kev txo qis los ntawm cerium trifluoride. Tsis tas li ntawd, cerium trifluoride tuaj yeem siv los ua cov khoom siv cerium-doped nano-luminescent (xws li CeF₃:Tb³⁺), uas tau siv rau hauv kev thaij duab txog tsiaj txhu thiab cov thev naus laus zis tso saib.
