NEODYMIUM NITRATE HEXAHYDRATE is used for glass, crystal and capacitors. Colours glass delicate shades ranging from pure violet through wine-red and warm gray. Light transmitted through such glass shows unusually sharp absorption bands. It is useful in protective lenses for welding goggles. It is also used in CRT displays to enhance contrast between reds and greens. It is highly valued in glass manufacturing for its attractive purple coloring to glass.
Neodymium(III) nitrate hexahydrate is used to prepare nanoparticles of neodymium oxybromide and neodymium oxide. It is also used in coloring glasses and for doping some glass lasers.
It crystallises with 5 and 6 molecules of H2O from concentrated solutions in dilute HNO3 by slow evaporation; 1 part is soluble in 10 parts of H2O.
