Lus qhia, Cuaj xyoo 57 ntawm lub rooj ntu.
Txhawm rau ua kom cov lus txheej txheem ntawm cov ntsiab lus zoo nkauj heev, cov neeg tau coj tawm 15 yam ntawm LanThant, uas nws Atomic lej nce ntxiv, thiab muab tso rau lawv cais nyob rau hauv lub rooj ntu. Lawv cov tshuaj lom neeg zoo sib xws. Lawv faib rau lub chaw siab thib peb nyob rau hauv kab lus thib rau, uas yog sib sau ua ke rau raws li "lus qhia" thiab lub ntiaj teb tsawg ". Raws li lub npe qhia, cov ntsiab lus ntawm Lanthhanum hauv lub ntiaj teb crust yog tsawg heev, thib ob tsuas yog rau cerium.
Thaum kawg ntawm 1838, Swedish Chemist Mossander tau hais txog tus oxide tshiab raws li lub ntiaj teb thiab lub caij ua kab. Txawm hais tias qhov xaus tau pom tau los ntawm ntau tus kws tshawb fawb, Mossander tseem muaj kev ua xyem xyav vim nws pom xim liab, qee zaum hauv paj yeeb dawb, thiab qee zaum hauv liab dawb li ib qho thib peb. Cov xwm txheej no ua rau nws ntseeg tias Lanthant yuav muaj qhov sib xyaw zoo li Ceeline.
LANTHAN HLAUyog nyiaj dawb mos hlau uas tuaj yeem raug forged, ncab, maj mam corrodes hauv dej txias, thiab tuaj yeem emit hydrogen roj. Nws tuaj yeem ncaj qha kev hnov qab nrog ntau tus tsis yog xim hlau xws li carbon, nitrogen, boron, selenium, thiab lwm yam.
Ib qho dawb amorphous hmoov thiab nonmagneticLanthhanum oxideyog siv dav hauv kev lag luam ntau lawm. Cov neeg siv cov lus Lanthhanum es tsis txhob sodium thiab calcium ua kom hloov Bentonite, tseem hu ua Phosphorus tus neeg sawv cev.
Lub Eutrophoricital ntawm lub cev dej yog feem ntau vim yog lub cev muaj roj ntau dhau, uas tau haus cov pa dej xiav thiab noj nyob rau hauv cov ntses tuag. Yog tias tsis tau kho nyob rau hauv lub sijhawm, dej yuav tsw tsw phem thiab dej ua haujlwm zoo yuav dhau los. Kev tso tawm cov dej txuas ntxiv ntawm cov dej hauv tsev thiab siv ntau dhau ntawm phosphorus muaj cov chiv ntawm phosphorus hauv dej. Hloov kho Bentonite muaj cov lus qhia ntxiv rau cov dej thiab adsorb zoo tshaj thosphorus hauv dej raws li nws cog rau hauv qab. Thaum nws nce mus rau hauv qab, nws kuj tseem tuaj yeem passivate phosphorus cov ntsiab lus hauv cov dej phosphorus nyob hauv daim ntawv ntawm cov tshuaj phosphorus nyob hauv cov dej phosphorus nyob hauv cov dej phosphorus hauv cov dej phosphorus hauv dej, yog li inhibiting txoj kev loj hlob, yog li inhibiting txoj kev loj hlob, yog li inhibiting txoj kev loj hlob, yog li inhibiting txoj kev loj hlob, yog li inhibiting txoj kev loj hlob, yog li inhibiting txoj kev loj hlob, yog li inhibiting txoj kev loj hlob, yog li inhibiting txoj kev loj hlob, yog li inhibiting txoj kev loj hlob hauv Luam tawm ntawm cov algae ntsuab-ntsuab, thiab kev daws tau zoo ntawm phosphorus tshwm sim los ntawm phosphorus hauv cov dej sib txawv xws li pas dej, cov dej thiab dej ntws.
Siab huvLanthhanum oxideKuj tseem siv tau los tsim cov ntsiab muag precision thiab siab refactical optactical fiber ntau. Lanthhant tseem tuaj yeem siv los ua cov ntaus tsaus ntuj, yog li cov tub rog tuaj yeem ua tiav cov kev sib ntaus ua haujlwm thaum hmo ntuj. Lanthhanb oxide tseem tuaj yeem siv los tsim cov ceramic capacitor, piezoelectric ceramics thiab duab xoo hluav taws xob.
Thaum tshawb nrhiav cov pob txha roj av, cov neeg tau tsom mus rau cov khoom siv kom huv, thiab cov khoom siv hydrogen cia yog tus yuam sij rau daim ntawv thov ntawm hydrogen. Vim yog cov nplaim taws thiab tawg ntawm hydrogen, hydrogen cia thooj voos kheej kheej tuaj yeem tshwm sim clumsy. Los ntawm kev tshawb nrhiav nruam nruam, cov tib neeg pom tias Lanthanum-Nickel Alloy, cov khoom siv hlau hlau, muaj lub peev xwm hlau muaj zog los ntes cov hydrogen. Nws tuaj yeem ntes cov tshuaj hydrogen molecules thiab decompose lawv mus rau hydrogen atoms, thiab tom qab ntawd khaws cov hydrogen atoms hauv cov hlau ntxaij ntxig los ua cov hlau hydride. Thaum cov quav tshuaj hlau no yog rhaub, lawv yuav rho tawm thiab tso tawm hydrogen nkaus, yog li lawv tuaj yeem siv los khaws cov roj ntsha li ntawm cov roj teeb thiab hybrid hluav taws xob tsheb.
