Preparation
editPraseodymium(III) nitride can be prepared by the reaction of nitrogen and metallic praseodymium on heating:
- 2 Pr + N2 → 2 PrN
It can also be prepared from the reaction of ammonia and praseodymium metal on heating:
- 2 Pr + 2 NH3 → 2 PrN + 3 H2
Properties
editPraseodymium(III) nitride forms black crystals of a cubic system. The space group is Fm3m,[4] with cell parameter a = 0.5165 nm, Z = 4, its structure similar to that of sodium chloride (NaCl).
The compound is readily hydrolyzed with water and reacts with acids.
Applications
editThe compound is used in high-end electric and semiconductor products, and as a raw material to produce phosphor. Also it is used as a magnetic material and sputtering target material.[5]
