Neodymium(III) hydroxide
Neodymium hydroxide is an insoluble inorganic compound with the chemical formula Nd3.
Preparation
Neodymium(III) nitrate and ammonia water will react to produce neodymium hydroxide:If the amount of Nd3 is 40g/L, the amount of ammonia water needed is 0.50 mol/L. The ammonia water is mixed into the Nd3 solution at the speed of 1.5mL/min, and polyethylene glycol is used to control pH. The process will produce neodymium hydroxide powder with grain size ≤1μm.
Chemical properties
Neodymium hydroxide can react with acid and produce neodymium salts:For example, to create neodymium acetate with neodymium hydroxide:
