Neodymium(III) hydroxide

Neodymium(III) hydroxide is an insoluble inorganic compound with the chemical formula Nd(OH)₃.

Preparation

Neodymium(III) nitrate and ammonia water will react to produce neodymium(III) hydroxide:

If the amount of Nd(NO₃)₃ is 40g/L, the amount of ammonia water needed is 0.50 mol/L. The ammonia water is mixed into the Nd(NO₃)₃ solution at the speed of 1.5mL/min, and polyethylene glycol is used to control pH. The process will produce neodymium(III) hydroxide powder with grain size ≤1μm.

Chemical properties

Neodymium(III) hydroxide can react with acid and produce neodymium salts:

For example, to create neodymium acetate with neodymium(III) hydroxide:
