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 zooLanthanum Fluoride.

Cov Nta Tseem Ceeb:

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

Cov tshuaj catalysts hauv kev lag luam tshuaj lom neeg: Lithium fluoride siv tau ua catalyst lossis catalyst carrier hauv kev lag luam tshuaj lom neeg, thiab siv rau hauv qee yam kev sib xyaw ua ke. Qhov tseem ceeb tshaj, nws yog ib qho tseem ceeb hauv kev npaj cov roj av catalytic cracking (FCC) catalysts, uas tuaj yeem txhim kho kev hloov pauv ntawm cov hydrocarbons. Nws cov nanoparticles kuj tau kawm ua cov roj nplua nyeem ntxiv, qhia txog cov khoom zoo heev.

Tshuaj Tshem Tawm Phosphate Hauv Pas Dej: Vim nws cov khoom siv tshuaj lom neeg, lanthanum fluoride tuaj yeem tshem tawm cov phosphate ntawm cov dej los ntawm kev nag, uas pab daws qhov teeb meem ntawm cov dej eutrophication. Nws cov nanomaterials kuj qhia txog peev xwm rau kev siv hauv kev kho ib puag ncig rau kev tshem tawm cov hlau hnyav ions (xws li cov mercury ions).

Cov Roj Teeb thiab Cov Khoom Siv Hluav Taws Xob: Vim nws muaj cov ionic conductivity siab, lanthanum fluoride yog cov khoom siv tseem ceeb rau cov roj teeb oxide khov (SOFC) thiab cov electrolytes khov. Nws kuj yog cov khoom siv raw nruab nrab rau kev npaj cov hlau lanthanum, uas yog siv rau hauv cov khoom siv khaws cia hluav taws xob xws li cov roj teeb nickel-hlau hydride. Hauv cov reactors ntsev molten, nws kuj tuaj yeem ua haujlwm ua cov dej txias thiab cov kuab tshuaj.

Cov tshuaj synthesis intermediates: Raws li qhov tseem ceeb ntawm lanthanum, lanthanum fluoride yog qhov tseem ceeb precursor rau synthesizing lwm cov lanthanum compounds (xws li lanthanum oxide). Nws tus kheej kuj yog ib qho khoom siv raw rau kev npaj ZBLAN fluoride iav, cov khoom siv laser siv lead ua tsis tshua muaj (xws li erbium-doped thiab neodymium-doped laser crystals) thiab cov khoom siv scintillation (siv hauv kev kho mob PET / CT imaging).
