Lanthanum Hydroxide

Short Description:

Lanthanum Hydroxide is a highly water insoluble crystalline Lanthanum source, which 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 that can then be dried in air. Lanthanum hydroxide does not react much with alkaline substances, however is slightly soluble in acidic solution. It is used compatibly with higher (basic) pH environments.

What is Lanthanum hydroxide hydrate used for?

Lanthanum Hydroxide, also called Lanthanum Hydrate, has diverse properties and uses, from base catalysis,glass,ceramic, electronic industry. to detection of carbon dioxide. It is also 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.
