White powder,insoluble in water,soluble in acids.As it is highly hygroscopic and picks up the moisture and carbon dioxide from air rapidly,it should be kept in sealed containers.

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.
