Neodymium tungstate

Neodymium tungstate is an inorganic compound, a salt of neodymium and tungstic acid with the chemical formula Nd2(WO4)3. It forms hydrated light purple crystals that are slightly soluble in water.

Preparation

 * Reacting neodymium(III) oxide and tungsten(VI) oxide would produce anhydrous neodymium tungstate:


 * The nonahydrate could be produced by the reaction of sodium tungstate and neodymium(III) nitrate:

Properties
Neodymium tungstate forms the crystal of a monoclinic crystal system, with space group A 2/a, lattice constants a = 1.151 nm, b = 1.159 nm, c = 0.775 nm and β = 109.67 °. It is insoluble in ethanol and acetone and sparingly soluble in water. It forms the nonahydrate Nd2(WO4)3·9H2O.
