Neodymium(III) hydroxide is an insoluble inorganic compound with the chemical formula Nd(OH)3. [2] [3]

Contents

Production

Neodymium(III) nitrate and ammonia water will react to produce neodymium(III) hydroxide [4]

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. [5]

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

Neodymium compounds are compounds formed by the lanthanide metal neodymium (Nd). In these compounds, neodymium generally exhibits the +3 oxidation state, such as NdCl3, Nd2(SO4)3 and Nd(CH3COO)3. Compounds with neodymium in the +2 oxidation state are also known, such as NdCl2 and NdI2. Some neodymium compounds have colors that vary based upon the type of lighting.

Neodymium(III) carbonate is an inorganic compound, a salt, where neodymium is in the +3 oxidation state and the carbonate ion is in the -2 oxidation state. It has a chemical formula of Nd2(CO3)3. The anhydrous form is purple-red, while the octahydrate is a pink solid. Both of these salts are insoluble in water.

Praseodymium(III) carbonate is an inorganic compound, with a chemical formula of Pr2(CO3)3. The anhydrous form is olive green, and many of its hydrates such as heptahydrate and octahydrate are known. They are all insoluble in water.

Europium compounds are compounds formed by the lanthanide metal europium (Eu). In these compounds, europium generally exhibits the +3 oxidation state, such as EuCl3, Eu(NO3)3 and Eu(CH3COO)3. Compounds with europium in the +2 oxidation state are also known. The +2 ion of europium is the most stable divalent ion of lanthanide metals in aqueous solution. Many europium compounds fluoresce under ultraviolet light due to the excitation of electrons to higher energy levels. Lipophilic europium complexes often feature acetylacetonate-like ligands, e.g., Eufod.
