Daim Ntawv Thov:
Lanthhanum nitrateyog tsuas yog thov hauv cov iav tshwj xeeb, kev kho dej thiab catalyst. Ntau yam sib xyaw ntawm cov lus Lanthhan thiab lwm yam tsawg-lub ntiaj teb-lub ntiaj teb cov ntsiab lus (Oxides, Chocoralides ntawm ntau yam catroleum cracking catalysts. Me me ntawm Lanthhanum ntxiv rau cov hlau txhim kho nws cov tsis tau zoo ntawm cov lus qhia, thiab kev cuam tshuam rau cov lus qhia thiab kev sib txawv thiab qhov kub thiab txias variations. Cov khoom lag luam me me hauv cov khoom lag luam uas tau siv rau cov phosphor, cov khoom siv kho qhov muag, ceramic), cov khoom siv sib nqus, cov tshuaj sib sib sib nqus thiab lwm yam khoom siv

Lanthhant nitrate yog yooj yim Deliquescent thiab muaj oxidizing cov khoom. Tshuaj lom neeg tsis zoo. Nqus tau cov lus qhia thiab nws cov pa taws thiab cov hmoov av tuaj yeem ua rau cov tsos mob xws li mob taub hau thiab xeev siab, nws tuaj yeem ua rau tuag taus. Vim tias cov lus piv txwv yog nitrate tau ua tiav, nws tau faib ua cov khoom tawg.
Lub cev thiab tshuaj lom neeg ntawm lanthhanum nitrate
Tsis muaj kob triclinic crystal. Melting taw tes 40 ℃. Yooj yim soluble hauv dej thiab ethanol, soluble hauv acetone. Thaum tshav kub kub rau 126 ℃ rau kev txiav txim siab, ua ntej los ua cov ntsev alkaline, thiab tom qab ntawd los tsim oxide. Thaum rhuab rau 800 ℃, nws decomposes rau hauv cov lus hauv lanthhanb. Nws yog ib qho yooj yim rau daim ntawv crystalline complex salts xws li cu [La (No3) 5] lossis mg [LA (NO3) 5] nrog tooj liab nitrate lossis magnesium nitrate. Tom qab sib tov thiab evaporating nrog ammonium nitrate cov tshuaj, loj muaj xim crystal hydrated ob hlis ntuj, thiab tom kawg tuaj yeem poob dej ntawm crystallization thaum rhawv ntawm 100 ℃. Thaum nws cuam tshuam nrog hydrogen peroxide, lanthhanum peroxide (LA2O5) HMOOV yog tsim [1.2].
