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
