Ntchito:
Lanthanum nitrate amagwiritsidwa ntchito makamaka mu galasi lapadera, chithandizo chamadzi ndi chothandizira. Mitundu yosiyanasiyana ya Lanthanum ndi zinthu zina zapadziko lapansi (Oxides, Chlorides, etc.) ndi zigawo za catalysis zosiyanasiyana, monga zopangira mafuta opangira mafuta. Zochepa za Lanthanum zomwe zimawonjezeredwa kuzitsulo zimathandizira kusungunuka kwake, kukana kukhudzidwa, ndi ductility, pamene kuwonjezera kwa Lanthanum ku Molybdenum kumachepetsa kuuma kwake ndi kukhudzidwa kwa kusiyana kwa kutentha. Zochepa za Lanthanum zilipo muzinthu zambiri zamadzimadzi kuti zichotse Phosphates zomwe zimadyetsa algae.Lanthanum Nitrate imagwiritsidwa ntchito popanga ternary catalysts, tungsten molybdenum electrodes, optical glass, phosphor, ceramic capacitor additives, magnetic materials, reagents mankhwala ndi mafakitale ena.

Zindikirani:Kupanga kwazinthu ndi kulongedza kutha kuchitidwa molingana ndi zomwe ogwiritsa ntchito.
Lanthanum nitrate ndi yosavuta kusungunuka ndipo imakhala ndi oxidizing. Zinthu Zowopsa za Chemical. Kukoka lanthanum ndi mankhwala ake mu utsi ndi fumbi kungayambitse zizindikiro monga mutu ndi nseru, ndipo zikavuta kwambiri, zimatha kupha. Chifukwa lanthanum nitrate imatha kuyaka, imayikidwa ngati chinthu chophulika.
Thupi ndi mankhwala katundu lanthanum nitrate
Mtundu wopanda mtundu wa kristalo wa triclinic. Malo osungunuka 40 ℃. Imasungunuka mosavuta m'madzi ndi ethanol, imasungunuka mu acetone. Kutenthetsa mpaka 126 ℃ kuti kuwola, choyamba kupanga mchere wamchere, kenako kupanga okusayidi. Ikatenthedwa mpaka 800 ℃, imawola kukhala lanthanum oxide. N'zosavuta kupanga mchere wambiri wa crystalline monga Cu [La (NO3) 5] kapena Mg [La (NO3) 5] ndi copper nitrate kapena magnesium nitrate. Pambuyo kusakaniza ndi evaporating ndi ammonium nitrate njira, lalikulu colorless galasi hydrated mchere awiri (NH4) 2 [La (NO3) 5] • 4H2O aumbike, ndipo yotsirizira akhoza kutaya madzi crystallization pamene kutentha pa 100 ℃. Ikalumikizana ndi hydrogen peroxide, ufa wa lanthanum peroxide (La2O5) umapangidwa [1.2].
