Neodymium(III) hydroxide is an insolubleinorganic compound with thechemical formula Nd(OH)3.[2][3]
Neodymium(III) nitrate andammonia water will react to produce neodymium(III) hydroxide:[4]
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, andpolyethylene glycol is used to control pH. The process will produce neodymium(III) hydroxide powder with grain size ≤1μm.[5]
Neodymium(III) hydroxide can react withacid and produceneodymium salts:
For example, to createneodymium acetate with neodymium(III) hydroxide:[6]
