Product Description
Lanthanum nitrate hexahydrate (CAS No. 10277-43-7) is a high-purity inorganic lanthanum compound typically present as colorless crystals with a characteristic nitrate odor. It exhibits excellent water solubility and can be easily incorporated into aqueous chemical systems.
Under normal storage conditions, lanthanum nitrate hexahydrate remains stable and maintains its chemical properties. When exposed to elevated temperatures, it undergoes decomposition and may release nitrogen oxide gases.
Due to its unique chemical characteristics, including high solubility, moisture absorption capability, and stable crystalline structure, lanthanum nitrate hexahydrate is widely used in chemical research, advanced material preparation, and industrial manufacturing processes requiring reliable lanthanum sources.
