Lanthanum hydroxide is La(OH)₃, an hydroxide of rare earth element lanthanum.

Properties

Production

Lanthanum hydroxide can be obtained by adding an alkali such as ammonia to aqueous solutions of lanthanum salts such as lanthanum nitrate. This produces a gel-like precipitate which can then be dried in air.

Alternatively, it can be produced by the action of water at 90°C on metallic lanthanum.
