Chemical compound

Neodymium molybdate is an inorganic compound, with the chemical formula of Nd2(MoO4)3.

## Preparation

[edit]

It can be prepared by reacting neodymium oxide and molybdenum trioxide at a high temperature:[2]

Nd2O3 \+ 3MoO3 → Nd2(MoO4)3

It can also be prepared by reacting neodymium nitrate and (NH4)6Mo7O24, treating the obtained precipitate at a high temperature.[1]

## Properties

[edit]

It reacts with sodium molybdate at a high temperature to obtain NaNd(MoO4)2.[3] It reacts at roughly 350°C to 700°C with hydrogen sulfide to obtain neodymium sulfide and molybdenum disulfide.[4] At roughly 780K to 870K, it can be reduced by hydrogen to obtain Nd2Mo3O9.[5]
