Isicelo:
I-Lanthanum Nitrate isetshenziswa ikakhulukazi engilazini ekhethekile, ukwelashwa kwamanzi kanye ne-catalyst. Izinhlanganisela ezihlukahlukene ze-Lanthanum nezinye izakhi zomhlaba ezingavamile (ama-Oxides, ama-Chlorides, njll.) ziyizingxenye ze-catalysis ehlukahlukene, njengama-catalysts e-petroleum cracking. Inani elincane le-Lanthanum elingezwe ensimbi lithuthukisa ukusebenziseka kwayo kalula, ukumelana nomthelela, kanye ne-ductility, kuyilapho ukungezwa kwe-Lanthanum ku-Molybdenum kunciphisa ubulukhuni bayo nokuzwela ekuhlukeni kwezinga lokushisa. Amanani amancane e-Lanthanum akhona emikhiqizweni eminingi yamachibi ukuze asuse amaPhosphates ondla ulwelwe.I-Lanthanum Nitrate isetshenziswa ekwenzeni ama-ternary catalysts, ama-electrodes e-tungsten molybdenum, ingilazi yokukhanya, i-phosphor, izithasiselo ze-ceramic capacitor, izinto zikamagnetic, ama-chemical reagents nezinye izimboni.

I-Lanthanum nitrate iyancipha kalula futhi inezinto ezikhipha i-oxidizing. Izinto Zamakhemikhali Eziyingozi. Ukuhogela i-lanthanum nezinhlanganisela zayo entuthwini nasothulini kungabangela izimpawu ezinjengokukhanda ikhanda nokucanuzela kwenhliziyo, futhi ezimweni ezimbi kakhulu, kungaholela ekufeni. Ngenxa yokuthi i-lanthanum nitrate inokuvutha, ihlukaniswa njengento eqhumayo.
Izinto ezibonakalayo namakhemikhali e-lanthanum nitrate
Ikristalu ye-triclinic engenambala. Iphuzu lokuncibilika lingu-40 ℃. Incibilika kalula emanzini ne-ethanol, inyibilika ku-acetone. Shisisa ufike ku-126 ℃ ukuze ubole, kuqala wenze usawoti we-alkaline, bese wenza i-oxide. Uma ishisa kufika ku-800 ℃, ibola ibe yi-lanthanum oxide. Kulula ukwakha usawoti oyinkimbinkimbi we-crystalline njenge-Cu [La (NO3) 5] noma i-Mg [La (NO3) 5] nge-nitrate yethusi noma i-magnesium nitrate. Ngemva kokuxuba nokuhwamuka ngesisombululo se-ammonium nitrate, i-crystal enkulu engenambala i-hydrated usawoti ophindwe kabili (NH4) 2 [La (NO3) 5] • I-4H2O iyakhiwa, futhi lokhu okulandelayo kungalahlekelwa amanzi e-crystallization lapho kushisa ku-100 ℃. Uma ihlangana ne-hydrogen peroxide, i-lanthanum peroxide (La2O5) i-powder ikhiqizwa [1.2].
