Isicelo:
I-Lanthanum Nitrate isetyenziswa kakhulu kwiglasi ekhethekileyo, unyango lwamanzi kunye ne-catalyst. Iikhompawundi ezahlukeneyo zeLanthanum kunye nezinye izinto ezinqabileyo zomhlaba (i-Oxides, i-Chlorides, njl.) zizinto ze-catalysis ezahlukeneyo, ezifana ne-petroleum cracking catalysts. Izixa ezincinci zeLanthanum ezongeziweyo kwintsimbi ziphucula ukonakala kwayo, ukuchasana nempembelelo, kunye ne-ductility, kanti ukongezwa kweLanthanum kwiMolybdenum kunciphisa ubunzima bayo kunye novelwano kwiinguqu zobushushu. Amanani amancinci eLanthanum akhoyo kwiimveliso ezininzi zamachibi ukususa iPhosphates ezondla i-algae.I-Nitrate yeLanthanum isetyenziselwa ukuveliswa kwe-ternary catalysts, i-tungsten molybdenum electrodes, i-glass optical, i-phosphor, i-ceramic capacitor additives, izixhobo zamagnetic, i-chemical reagents kunye namanye amashishini.

Phawula:Ukuveliswa kwemveliso kunye nokupakishwa kunokwenziwa ngokweenkcukacha zomsebenzisi.
I-Lanthanum nitrate ilula kwaye ineempawu ze-oxidizing. Izinto ezinobungozi zeMichiza. Ukuphefumla i-lanthanum kunye neekhompawundi zayo kumsi kunye nothuli kunokubangela iimpawu ezinjengeentloko kunye nesicaphucaphu, kwaye kwiimeko ezinzima, kunokukhokelela ekufeni. Ngenxa yokuba i-lanthanum nitrate inokutsha, ihlelwa njengento eqhumayo.
Iimpawu ezibonakalayo kunye neekhemikhali ze-lanthanum nitrate
Ikristale yetriclinic engenambala. Indawo yokunyibilika ngama-40 ℃. Inyibilika ngokulula emanzini nakwi-ethanol, inyibilika kwi-acetone. Ukufudumala ukuya kwi-126 ℃ ukubola, kuqala ukwenza ityuwa yealkaline, kwaye wenze i-oxide. Xa ishushu kwi 800 ℃, ibola ibe yilanthanum oxide. Kulula ukwenza i-crystalline i-salts eziyinkimbinkimbi ezifana neCu [La (NO3) 5] okanye i-Mg [La (NO3) 5] nge-nitrate yobhedu okanye i-nitrate ye-magnesium. Emva kokuxuba kunye ne-evaporating isisombululo se-ammonium nitrate, i-crystal enkulu engenambala i-hydrated ityuwa ephindwe kabini (NH4) 2 [La (NO3) 5] • I-4H2O yenziwe, kwaye le yokugqibela inokulahlekelwa ngamanzi e-crystallization xa ishushu kwi-100 ℃. Xa idibana ne-hydrogen peroxide, i-lanthanum peroxide (La2O5) ipowder yenziwe [1.2].
