Usage

Physical Properties

White crystalline solid; hygroscopic; decomposes around 40°C; very soluble in water and alcohol.

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.

Chemical Properties

white crystals

Uses

Different sources of media describe the Uses of 10277-43-7 differently. You can refer to the following data:
1. Starting material for the electrochemical synthesis of a LaMnO3 thin film coating on stainless steel substrates. A novel solvothermal process for formation of doped lanthanide oxysulfide, La2O2S, was developed in order to advance possible applications of this material in phosphors, fluorescent display tubes or heat transfer measurement. Lanthanum Nitrate is mainly applied in specialty glass, water treatment and catalyst. Various compounds of Lanthanum and other rare-earth elements (Oxides, Chlorides, etc.) are components of various catalysis, such as petroleum cracking catalysts. Small amounts of Lanthanum added to steel improves its malleability, resistance to impact, and ductility, whereas addition of Lanthanum to Molybdenum decreases its hardness and sensitivity to temperature variations. Small amounts of Lanthanum are present in many pool products to remove the Phosphates that feed algae.
2. Starting material for the electrochemical synthesis of a LaMnO3 thin film coating on stainless steel substrates. A novel solvothermal process for formation of doped lanthanide oxysulfide, La2O2S, was developed in order to advance possible applications of this material in phosphors, fluorescent display tubes or heat transfer measurement.
