Daim ntawv thov:
Lanthanum nitrateyog tsuas yog siv rau hauv cov iav tshwj xeeb, dej kho thiab catalyst. Ntau lub tebchaw ntawm Lanthanum thiab lwm yam tsis tshua muaj hauv ntiaj teb (Oxides, Chlorides, thiab lwm yam) yog cov khoom ntawm ntau yam catalysis, xws li roj av cracking catalysts. Cov nyiaj me me ntawm Lanthanum ntxiv rau cov hlau txhim kho nws txoj kev ua tau zoo, tiv thaiv kev cuam tshuam, thiab ductility, qhov ntxiv ntawm Lanthanum rau Molybdenum txo nws qhov nyuaj thiab rhiab heev rau qhov kub thiab txias. Cov khoom me me ntawm Lanthanum muaj nyob rau hauv ntau lub pas dej ua ke kom tshem tawm cov Phosphates uas pub algae.Lanthanum Nitrate yog siv rau hauv kev tsim cov ternary catalysts, tungsten molybdenum electrodes, optical iav, phosphor, ceramic capacitor additives, magnetic cov ntaub ntawv, tshuaj reagents thiab lwm yam lag luam.

Nco tseg:Kev tsim khoom thiab ntim khoom tuaj yeem ua raws li cov neeg siv khoom tshwj xeeb.
Lanthanum nitrate yog yooj yim deliquescent thiab muaj oxidizing zog. Tshuaj lom neeg. Kev nqus cov lanthanum thiab nws cov ntsiab lus hauv cov pa luam yeeb thiab plua plav tuaj yeem ua rau cov tsos mob xws li mob taub hau thiab xeev siab, thiab thaum mob hnyav, nws tuaj yeem ua rau tuag taus. Vim hais tias lanthanum nitrate muaj combustibility, nws raug cais raws li cov khoom tawg.
Lub cev thiab tshuaj muaj zog ntawm lanthanum nitrate
Xim tsis muaj xim triclinic siv lead ua. Melting point 40 ℃. Yooj yim soluble hauv dej thiab ethanol, soluble hauv acetone. Thaum tshav kub kub rau 126 ℃ rau decomposition, ua ntej tsim ib qho alkaline ntsev, thiab tom qab ntawd los ua ib qho oxide. Thaum rhuab mus rau 800 ℃, nws decomposes rau hauv lanthanum oxide. Nws yog ib qho yooj yim los tsim crystalline complex ntsev xws li Cu [La (NO3) 5] los yog Mg [La (NO3) 5] nrog tooj liab nitrate los yog magnesium nitrate. Tom qab sib tov thiab evaporating nrog ammonium nitrate tov, loj tsis muaj kob crystal hydrated ob ntsev (NH4) 2 [La (NO3) 5] • 4H2O yog tsim, thiab lub tom kawg yuav poob dej crystallization thaum rhuab ntawm 100 ℃. Thaum nws cuam tshuam nrog hydrogen peroxide, lanthanum peroxide (La2O5) hmoov yog tsim [1.2].
