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 isetshenziselwa ukwakhiwa kwama-ternary catalysts, ama-electrodes e-tungsten molybdenum, ingilazi yokukhanya, i-phosphor, izithasiselo ze-ceramic capacitor, izinto kazibuthe, ama-chemical reagents nezinye izimboni.

Ukupakishwa:Iphakethe le-vacuum 1, 2, 5, 25, 50 kg/piece, iphakethe lebhakede lekhadibhodi 25, 50 kg / ucezu, olulukiweisikhwama ukupakisha 25, 50, 500, 1000 kg/piece.

Qaphela:Ukukhiqizwa komkhiqizo kanye nokupakishwa kungenziwa ngokuya ngokucaciswa komsebenzisi.

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].
