Neodymium Nitrate Hexahydrate (Nd(NO₃)₃·6H₂O; MW 438.35 g/mol) is a rare earth nitrate salt presenting as purple, water-soluble crystals with a melting point of 69–71 °C and a density of 2.26 g/cm³. It is also soluble in alcohol. Commercially available material is quoted at TREO ≥ 37–38 % with Nd₂O₃/TREO reaching 99 %–99.9 %, spanning 2N to 4N grades; related forms include the anhydrous salt (CAS 10045-95-1) and 30–50 % aqueous solution.
The compound serves as a primary neodymium source across catalyst impregnation, specialty glass, advanced ceramics, and precursor chemistry. Its high solubility and controlled nitrate decomposition profile make it well suited to solution-phase processing routes where precise Nd loading and uniform distribution are required.
