Praseodymium nitride is a binary inorganic compound of praseodymium and nitrogen.[2] Its chemical formula is PrN.[3] The compound forms black crystals, and reacts with water.
Synthesis
- Reaction of nitrogen and metallic praseodymium on heating:
- [math]\displaystyle{ \mathsf{ 2 Pr + N_2 \ \xrightarrow{800-1000^oC}\ 2 PrN } }[/math]
- Reaction of ammonia and praseodymium metal on heating:
- [math]\displaystyle{ \mathsf{ 2 Pr + 2 NH_3 \ \xrightarrow{200-600^oC}\ 2 PrN + 3H_2 } }[/math]
Properties
Praseodymium 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
The 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]
