Neodymium molybdate is an inorganic compound, with the chemical formula of Nd<sub>2</sub>(MoO<sub>4</sub>)<sub>3</sub>.
It can be prepared by reacting neodymium oxide and molybdenum trioxide at a high temperature:
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.
It reacts with sodium molybdate at a high temperature to obtain NaNd(MoO<sub>4</sub>)<sub>2</sub>. It reacts at roughly 350ðC to 700ðC 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>.
