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:《无机化合物制备手册》. 朱文祥 主编. 化学工业出版社. 【III-119】氢氧化钕（neodymium hydroxide） 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 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.刘治平, 王晓铁. 氢氧化镧和氢氧化钕微粉的制备[J]. 《稀土》. Vol.25 No.3 Jun.2004

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
