Product Description
Neodymium(III) nitrate hexahydrate (CAS 16454-60-7, Nd(NO₃)₃·6H₂O) is a purple to violet crystalline rare-earth salt, soluble in water and polar solvents. It is the standard water-soluble neodymium source used as a precursor for neodymium oxide, neodymium-doped optical materials, catalysts and advanced ceramic components.
Key features:
Purple/violet crystals with high purity (99.9% – 99.99% rare-earth basis).
Highly soluble in water, easy to dose and formulate.
Clean precursor — decomposes on heating to Nd₂O₃ with little residue.
Widely used in neodymium-doped glass and phosphors.
Good starting material for sol-gel, CVD and wet-chemical synthesis.
Tight control of other rare-earth impurities (La, Ce, Pr, Sm).

Product Application
Neodymium(III) nitrate hexahydrate is a versatile rare-earth feedstock whose demand comes mainly from advanced materials, optical glass, catalysts and electronic ceramics.
In neodymium oxide and magnet production, it is the preferred precursor for calcination to Nd₂O₃, which is further used in NdFeB permanent magnets, neodymium-iron-boron alloys and glass polishing compounds.
In optical glass and phosphors, it is used to produce neodymium-doped glass for welding goggles, lasers (Nd:glass) and color-filter glass, where the sharp absorption bands of Nd³⁺ give distinctive violet-to-red shades and spectral filtering.
In catalysis and organic synthesis, Nd(NO₃)₃ serves as a Lewis acid catalyst or catalyst precursor for Friedlander-type quinoline synthesis, C–C coupling and other fine-chemical reactions.
In electronic and functional materials, it is used in perovskite-type solid oxide fuel cells, Nd-doped vanadium oxide nanomaterials for supercapacitors, ceramic capacitors, and as a dopant in thin-film and sol-gel coatings.
