Qhov muaj pes tsawg leeg ntawm Lanthhanum Carbonate
Lanthhanum carbonateyog ib qho kev ua yeeb yam tseem ceeb tsim ntawmlus qhia, carbon, thiab cov pa oxygen. Nws cov mis mis yog LA2 (CO3) 3, uas yog La sawv cev rau Lanthhanum caij thiab CO3 sawv cev cov tshuaj carbonate ion.Lanthhanum carbonateYog ib qho dawb crystalline khoom nrog zoo thermal thiab tshuaj ruaj khov.
Muaj ntau txoj hauv kev rau kev npaj cov avthanum carbonate.Cov txheej txheem sib xws yog los uaLANTHAN HLAUnrog Dilute Nitrice acid kom tau cov lus qhia tsis zoo, uas yog tom qab ntawd reacted nrog sodium carbonate los uaLanthhanum Carbonatenag lossis daus. Ntxiv rau,Lanthhanum CarbonateKuj tseem tuaj yeem tau txais los ntawm reacting sodium carbonate nrog cov tshuaj chloride.
Lanthhanum carbonate muaj ntau cov kev thov tseem ceeb.Firstly,Lanthhanum CarbonateYuav siv tau ua ib qho tseem ceeb raw rau cov hlau.Lus qhiayog aTsis tshua muaj ntiaj teb hlauNrog tseem ceeb sib nqus, kho qhov muag, thiab electrochemical cov khoom, siv dav hauv cov liaj teb xws li cov khoom siv hluav taws xob xws li, ntsuas hluav taws xob, thiab metallurgy.Lanthhanum carbonate, raws li ib tug tseem ceeb ua ntej ntawm Lanthanide cov hlau, tuaj yeem muab cov khoom siv tseem ceeb rau cov ntawv thov hauv cov teb no.
Lanthhanum carbonateKuj tseem siv tau los npaj lwm cov chaw sib txuas. Piv txwv li, rov qabLanthhanum CarbonateNrog sulfuric acid los tsim cov lus qhia sulfate tuaj yeem siv los npaj cov catalysts, roj teeb, thiab lwm yam. Cov tshuaj tiv thaiv ntawmLanthhanum Carbonatenrog ammonium nitrate ua ammonium nitrate ntawmlus qhia, uas tuaj yeem siv los npaj cov hlau hlau oxides,Lanthhanum oxide, thiab lwm yam.
Lanthhanum carbonateKuj tseem muaj qee yam tshuaj ntsuab tus nqi. Kev tshawb fawb tau pom tiasLanthhanum Carbonatetuaj yeem siv los kho hyperphosphatemia. Hyperphosphatemia yog ib qho kab mob raum, feem ntau nrog kev nce hauv phosphorus qib hauv cov ntshav.Lanthhanum carbonatetuaj yeem sib txuas nrog phosphorus nyob rau hauv cov zaub mov ua cov tshuaj insoluble, yog txo qhov nqus ntawm phosphorus hauv cov ntshav, ua si lub luag haujlwm ntawm kev kho mob.
Lanthhanum carbonateKuj tseem siv tau los npaj cov ntaub ntawv ceramic. Vim nws zoo heev thermal thiab tshuaj ruaj khov,Lanthhanum Carbonatetuaj yeem txhim kho lub zog, hardness, thiab hnav tsis kam ntawm cov khoom sib xyaw. Yog li ntawd, hauv kev lag luam ceramic,Lanthhanum CarbonateFeem ntau siv los npaj cov ntaub ntawv xws li cov khoom siv kub siab, hluav taws xob ceramics, kho qhov muag tshiab, thiab lwm yam.
Lanthhanum carbonateKuj tseem siv tau rau kev tiv thaiv ib puag ncig. Vim nws cov kev kawm muaj peev xwm thiab kev ua haujlwm catalytic,Lanthhanum CarbonateYuav siv tau rau hauv ib puag ncig kev kho technologies xws li kev kho dej khib nyiab thiab tso pa ua kom huv. Piv txwv li, los ntawm reactingLanthhanum CarbonateNrog cov hlau hnyav rau hauv dej kom ua tiav los ua insoluble precoipitates, lub hom phiaj ntawm kev tshem cov hlau hnyav tau ua tiav.
Lanthhanum carbonateyog ib qho khoom siv tsis tseem ceeb nrog cov ntawv thov txuas ntxiv. It is not only an important raw material for lanthanide metals, but can also be used in the preparation of other compounds, treatment of hyperphosphatemia, preparation of ceramic materials, and environmental protection. Nrog kev txhim kho kev txhim kho ntawm kev tshawb fawb thiab thev naus laus zis, daim ntawv thov kev cia siab ntawmLanthhanum Carbonateyuav muaj dav dav.
