Neodymium molybdate is an inorganic compound, with the chemical formula of Nd2(MoO4)3.
Preparation
It can be prepared by reacting neodymium oxide and molybdenum trioxide at a high temperature:[1]
- 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.[2]
Properties
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]
