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 Oxide.

Cov Nta Tseem Ceeb:

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

Cov iav kho qhov muag thiab cov khoom siv ua los ntawm av nplaum: Lanthanum oxide yog cov khoom siv tseem ceeb rau kev tsim cov iav kho qhov muag thiab cov fibers kho qhov muag, ua rau cov ntsuas refractive thiab cov khoom tawg ntawm cov iav zoo dua. Nws yog siv dav hauv kev tsim cov iav kho qhov muag siab heev rau cov koob yees duab thiab cov tshuab microscopes. Hauv kev lag luam ntawm cov khoom siv hluav taws xob, nws yog siv los ua cov khoom ntxiv los tsim cov capacitors ceramic thiab piezoelectric ceramics los txhim kho cov khoom hluav taws xob thiab qhov kub thiab txias ntawm cov ntaub ntawv.

Catalyst: Hauv kev lag luam petrochemical, lanthanum oxide yog siv ua ib qho tseem ceeb ntawm catalytic cracking (FCC) catalysts, uas pab ua kom cov zis thiab qhov zoo ntawm roj av ntau ntxiv. Nws kuj tseem tuaj yeem ua haujlwm ua tus catalyst rau cov tshuaj tiv thaiv tshwj xeeb, xws li kev oxidation ntawm carbon monoxide thiab cov tshuaj tiv thaiv ntawm methane oxidation los tsim ethane thiab ethylene.

Cov ntaub ntawv ua haujlwm: Lanthanum oxide yog cov khoom siv raw rau kev npaj lanthanum boride (LaB2)₆), uas yog cov khoom siv cathode zoo heev rau kev tso tawm cov cua sov thermoelectronic. Lanthanum oxide kuj muaj cov ntawv thov tseem ceeb hauv cov teb xws li cov ntaub ntawv khaws cia hydrogen thiab cov roj cell. Piv txwv li, lanthanum-nickel alloys tuaj yeem siv rau kev khaws cia hydrogen.
