Application:
Lanthanum Nitrate inonyanya kuiswa mune yakakosha girazi, kurapwa kwemvura uye catalyst. Mishonga yakasiyana-siyana yeLanthanum uye zvimwe zvisingawanzoitiki-pasi zvinhu (Oxides, Chlorides, nezvimwewo) zvikamu zvezvakasiyana-siyana zvinokonzera, zvakadai se petroleum cracking catalysts. Zvishoma zveLanthanum yakawedzerwa kune simbi inovandudza kusagadzika kwayo, kuramba kukanganiswa, uye ductility, nepo kuwedzera kweLanthanum kuMolybdenum kunoderedza kuomarara kwayo uye kunzwa kune tembiricha kusiyana. Zvishoma zvishoma zveLanthanum zviripo muzvigadzirwa zvemadziva akawanda kubvisa Phosphates inodyisa algae.Lanthanum Nitrate inoshandiswa mukugadzira ternary catalysts, tungsten molybdenum electrodes, optical glass, phosphor, ceramic capacitor additives, magnetic materials, chemical reagents uye mamwe maindasitiri.

Lanthanum nitrate iri nyore kuita deliquescent uye ine oxidizing properties. Hazardous Chemical Substances. Kufema lanthanum nemakomboni ayo muutsi neguruva kunogona kukonzera zviratidzo zvakaita sekutemwa nemusoro uye kusvotwa, uye muzviitiko zvakanyanya, zvinogona kutungamirira kurufu. Nokuti lanthanum nitrate ine moto, inorondedzerwa sechinhu chinoputika.
Zvenyama uye zvemakemikari zvimiro zve lanthanum nitrate
isina ruvara triclinic crystal. Kunyungudika 40 ℃. Zviri nyore kunyungudika mumvura uye ethanol, soluble muacetone. Kupisa kusvika 126 ℃ yekuora, kutanga kuumba alkaline munyu, uyezve kugadzira oxide. Kana yapisa kusvika 800 ℃, inoora kuita lanthanum oxide. Zviri nyore kuumba crystalline yakaoma munyu yakadai seCu [La (NO3) 5] kana Mg [La (NO3) 5] nemhangura nitrate kana magnesium nitrate. Mushure mokusanganiswa uye kubuda neammonium nitrate solution, yakakura isina mavara crystal hydrated kaviri munyu (NH4) 2 [La (NO3) 5] • 4H2O inoumbwa, uye iyo yekupedzisira inogona kurasikirwa nemvura yecrystallization kana inopisa pa100 ℃. Painopindirana nehydrogen peroxide, lanthanum peroxide (La2O5) powder inogadzirwa [1.2].
