Qhov sib xyaw ntawm lanthanum carbonate
Lanthanum carbonateyog ib qho tseem ceeb tshuaj lom neeg muaj pes tsawg leeglanthanum, carbon, thiab oxygen.Nws cov qauv tshuaj yog La2 (CO3) 3, qhov twg La sawv cev rau lanthanum keeb thiab CO3 sawv cev rau carbonate ion.Lanthanum carbonateyog dawb crystalline khoom nrog zoo thermal thiab tshuaj stability.
Muaj ntau txoj hauv kev los npaj lanthanum carbonate.Txoj hauv kev zoo tshaj plaws yog los teblanthanum hlaunrog dilute nitric acid kom tau lanthanum nitrate, uas yog ces reacted nrog sodium carbonate rau daim ntawv.lanthanum carbonatenag xob nag cua.Ntxiv rau,lanthanum carbonatetuaj yeem tau txais los ntawm kev ua haujlwm sodium carbonate nrog lanthanum chloride.
Lanthanum carbonate muaj ntau yam kev siv tseem ceeb.Ua ntej,lanthanum carbonatetuaj yeem siv los ua cov khoom siv tseem ceeb rau cov hlau lanthanide.Lanthanumyog arare ntiaj teb hlaunrog cov khoom siv hlau nplaum tseem ceeb, kho qhov muag, thiab electrochemical, dav siv hauv kev lag luam xws li electronics, optoelectronics, catalysis, thiab metallurgy.Lanthanum carbonate, ua ib qho tseem ceeb ua ntej ntawm cov hlau lanthanide, tuaj yeem muab cov khoom siv tseem ceeb rau kev siv hauv cov teb no.
Lanthanum carbonatekuj siv tau los npaj lwm cov tebchaw.Piv txwv li, reactinglanthanum carbonatenrog sulfuric acid los tsim lanthanum sulfate tuaj yeem siv los npaj cov catalysts, cov khoom siv roj teeb, thiab lwm yam.lanthanum carbonatenrog ammonium nitrate tsim ammonium nitrate ntawmlanthanum, uas tuaj yeem siv los npaj lanthanide hlau oxides,lanthanum oxide, lwm.
Lanthanum carbonatekuj muaj qee yam kev siv tshuaj muaj nqis.Kev tshawb fawb tau qhia tiaslanthanum carbonatetuaj yeem siv los kho hyperphosphatemia.Hyperphosphatemia yog ib hom kab mob raum, feem ntau nrog los ntawm kev nce qib ntawm phosphorus hauv cov ntshav.Lanthanum carbonatetuaj yeem ua ke nrog phosphorus hauv cov zaub mov los tsim cov tshuaj insoluble, yog li txo qhov nqus ntawm phosphorus thiab cov concentration ntawm phosphorus hauv cov ntshav, ua si lub luag haujlwm kho mob.
Lanthanum carbonatetuaj yeem siv los npaj cov ntaub ntawv ceramic.Vim nws zoo heev thermal thiab tshuaj stability,lanthanum carbonatetuaj yeem txhim kho lub zog, hardness, thiab hnav tsis kam ntawm cov ntaub ntawv ceramic.Yog li ntawd, hauv kev lag luam ceramic,lanthanum carbonatefeem ntau yog siv los npaj cov ntaub ntawv xws li kub-kub ceramics, hluav taws xob ceramics, optical ceramics, thiab lwm yam.
Lanthanum carbonatekuj tseem siv tau rau kev tiv thaiv ib puag ncig.Vim nws lub peev xwm adsorption thiab kev ua haujlwm catalytic,lanthanum carbonatetuaj yeem siv nyob rau hauv ib puag ncig kev kho thev naus laus zis xws li kev kho cov dej khib nyiab thiab cov pa roj purification.Piv txwv li, los ntawm reactinglanthanum carbonatenrog hnyav hlau ions nyob rau hauv cov dej khib nyiab los tsim insoluble precipitates, lub hom phiaj ntawm kev tshem tawm cov hlau hnyav yog tiav.
Lanthanum carbonateyog ib qho tseem ceeb ntawm cov khoom siv tshuaj lom neeg nrog cov nqi siv dav.Nws tsis yog tsuas yog ib qho tseem ceeb raw khoom rau lanthanide hlau, tab sis kuj siv tau nyob rau hauv kev npaj ntawm lwm cov tebchaw, kev kho mob ntawm hyperphosphatemia, kev npaj cov ntaub ntawv ceramic, thiab kev tiv thaiv ib puag ncig.Nrog rau kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis, daim ntawv thov kev cia siab ntawmlanthanum carbonateyuav dav dua.
