Product Description of Lanthanum Nitrate Hexahydrate CAS#10277-43-7
Lanthanum nitrate hexahydrate is a colorless crystalline material with a typical nitrate odor. It is stable under normal room temperature conditions but decomposes when heated, emitting toxic nitrogen oxide gases. It is highly soluble in water and hygroscopic, absorbing moisture from the air.
