Used in Water Treatment:
Lanthanum(III) nitrate hexahydrate is used as a water treatment agent to remove phosphates that feed algae, helping to maintain clean and healthy water environments.
Used in Catalysts:
Lanthanum(III) nitrate hexahydrate is used as a component in various catalysts, such as petroleum cracking catalysts, due to its unique chemical properties.
Used in Stainless Steel Coating:
Lanthanum(III) nitrate hexahydrate is used as a starting material for the electrochemical synthesis of a LaMnO3 thin film coating on stainless steel substrates, enhancing the steel's properties.
Used in Phosphors and Fluorescent Display Tubes:
Lanthanum(III) nitrate hexahydrate is used as a starting material in a novel solvothermal process for the formation of doped lanthanide oxysulfide, La2O2S, which has potential applications in phosphors, fluorescent display tubes, and heat transfer measurement.

Preparation

The salt is prepared by dissolution of lanthanum oxide, hydroxide or carbonate in nitric acid, followed by crystallization, and obtained as a hexahydrate. The general reactions are as follows: La2O3 + 6HNO3 → 2La(NO3)3 + 3H2O La (OH)3 + 3HNO3 → La(NO3)3 + 3H2O La2 (CO3)3 + 6HNO3 → 2La(NO3)3 + 3CO2 + 3H2O

Reactions

Thermal dissociation yields lanthanum oxide, La2O3. Its reactions in aqueous solutions are those of La3+ ion. It forms double salts with magnesium, calcium and ammonium nitrates and many other salts when mixed in stoichiometic amounts. Such double salts are obtained from solution mixtures on crystallization and may vary in their compositions.

Air & Water Reactions

Deliquescent. Water soluble.

Reactivity Profile
