## Production

React neodymium(III) nitrate and ammonia water, to produce neodymium(III) hydroxide[2]

Nd(NO3)3 \+ 3 NH3·H2O → Nd(OH)3↓ + 3 NH4NO3

If the amount of Nd(NO3)3 is 40g/L，the amount of ammonia water is 0.50 mol/L; put ammonia water into Nd(NO3)3 solution at the speed of 1.5mL/min, and control pH at 7.35，use polyethylene glycol as scatterer, it will produce neodymium(III) hydroxide powder with grain size ≤1μm。[3]

## Chemical properties

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

Nd(OH)3 \+ 3 H+ → Nd3+ \+ 3 H2O

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

Nd(OH)3 \+ 3CH3COOH → Nd(CH3COO)3 \+ 3H2O
