Codsiga:
Lanthanum Nitratewaxaa inta badan lagu dabaqaa galaas khaas ah, daaweynta biyaha iyo kicinta. Iskudhisyo kala duwan oo Lanthanum ah iyo walxaha kale ee dhifka ah ee dhulka (Oxides, Chlorides, iwm.) waa qaybo ka mid ah kicinta kala duwan, sida kicinta batroolka. Qadar yar oo Lanthanum ah oo lagu daray birta waxay wanaajisaa awood-xumada, caabbinta saamaynta, iyo ductility, halka ku-darka Lanthanum ee Molybdenum ay hoos u dhigto adayga iyo dareenka kala duwanaanshaha heerkulka. Qadar yar oo Lanthanum ah ayaa ku jira badeecooyin badan oo barkad ah si looga saaro Fosfat-yada quudiya algae.

Nitrate-ka Lanthanum si sahal ah ayuu u dami wuxuuna leeyahay sifooyin oksaydheyn ah. Walxaha Kiimikada halista ah. Neefsashada lanthanum iyo xeryahooda ee qiiqa iyo boodhka waxay keeni kartaa calaamado ay ka mid yihiin madax-xanuun iyo lallabo, xaaladaha daranna waxay keeni kartaa dhimasho. Sababtoo ah amooniyam lanthanum wuxuu leeyahay gubasho, waxaa loo kala saaraa walxo qarxa.
Astaamaha jireed iyo kiimikaad ee lanthanum nitrate
crystal triclin aan midab lahayn. Barta dhalaalka 40 ℃. Si fudud ugu milmay biyaha iyo ethanol, ku milmay acetone. Kuleyl ilaa 126 ℃ si aad u burburto, marka hore si aad u sameyso milix alkaline ah, ka dibna si aad u sameysid oxide. Marka la kululeeyo ilaa 800 ℃, waxay u kala baxdaa lanthanum oxide. Way fududahay in la sameeyo cusbada isku dhafan ee crystalline sida Cu [La (NO3) 5] ama Mg [La (NO3) 5] oo leh nitrate copper ama magnesium nitrate. Ka dib marka la isku daro oo la uumibaxo xal ammonium nitrate, cusbo laba jibbaaran oo leh crystall aan midab lahayn (NH4) 2 [La (NO3) 5] • 4H2O ayaa la sameeyay, kan dambena wuxuu lumin karaa biyaha crystallization marka lagu kululeeyo 100 ℃. Marka ay la falgasho hydrogen peroxide, lanthanum peroxide (La2O5) budada ayaa la soo saaraa [1.2].
