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

Contents

Preparation

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: [6]

Nd(OH)3 + 3CH3COOH → Nd(CH3COO)3 + 3H2O

Neodymium(III) chloride or neodymium trichloride is a chemical compound of neodymium and chlorine with the formula NdCl3. This anhydrous compound is a mauve-colored solid that rapidly absorbs water on exposure to air to form a purple-colored hexahydrate, NdCl3·6H2O. Neodymium(III) chloride is produced from minerals monazite and bastnäsite using a complex multistage extraction process. The chloride has several important applications as an intermediate chemical for production of neodymium metal and neodymium-based lasers and optical fibers. Other applications include a catalyst in organic synthesis and in decomposition of waste water contamination, corrosion protection of aluminium and its alloys, and fluorescent labeling of organic molecules (DNA).

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.
