Neodymium molybdate

Neodymium molybdate is an inorganic compound, with the chemical formula of Nd<sub>2</sub>(MoO<sub>4</sub>)<sub>3</sub>.

Preparation

It can be prepared by reacting neodymium oxide and molybdenum trioxide at a high temperature:

Nd<sub>2</sub>O<sub>3</sub> + 3MoO<sub>3</sub> → Nd<sub>2</sub>(MoO<sub>4</sub>)<sub>3</sub>

It can also be prepared by reacting neodymium nitrate and (NH<sub>4</sub>)<sub>6</sub>Mo<sub>7</sub>O<sub>24</sub>, treating the obtained precipitate at a high temperature.

Properties

It reacts with sodium molybdate at a high temperature to obtain NaNd(MoO<sub>4</sub>)<sub>2</sub>. It reacts at roughly 350°C to 700°C with hydrogen sulfide to obtain neodymium sulfide and molybdenum disulfide. At roughly 780K to 870K, it can be reduced by hydrogen to obtain Nd<sub>2</sub>Mo<sub>3</sub>O<sub>9</sub>.
