LANTHANUM HYDROXIDE Usage And Synthesis
UsesLanthanum Hydroxide, also called Lanthanum Hydrate, 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.
Chemical Propertieswhite, amorphous precipitate; absorbs CO2 [MER06]
Physical propertiesWhite amorphous solid; decomposes on heating; insoluble in water.
UsesLanthanum hydroxide is used to prepare other lanthanum salts.
UsesLanthanum(III) hydroxide is used in three way catalyst, glass, ceramic and electronic industry.
PreparationLanthanum hydroxide is precipitated by adding excess of caustic soda, caustic potash or ammonia to an aqueous solution of a La3+ salt, such as LaCl3, La(NO3)3 or La(SO4)3:
La3+ + 3OHˉ → La(OH)3
.

Flammability and ExplosibilityNonflammable
