Chemical compound
Lanthanum nitride is a binary
inorganic compound of
lanthanum and
nitride with the chemical formula LaN.
[1]
[2]
Preparation
Lanthanum nitride can be prepared from the reaction of nitrogen and lanthanum trihydride:
- 2LaH3 + N2 → 2LaN + 3H2
It can also be prepared from the reaction of
ammonia and lanthanum trihydride:
[3]
- LaH3 + NH3 → LaN + 3H2
The reaction of nitrogen and lanthanum amalgam can also work:
[4]
- 2La + N2 → 2LaN
Physical properties
Lanthanum nitride forms black powder that is insoluble in water.
[1] Their crystals are of the
cubic system with the Fm3m
space group.
[5]
It is paramagnetic.
Chemical properties
Lanthanum nitride reacts with water and moisture from the air:
[6]
- LaN + 3H2O → La(OH)3 + NH3
It reacts with acids:
- LaN + 4HCl → LaCl3 + NH4Cl
Uses
LaN is used as a LED material, magnetic material,
semiconductor,
refractory material, dyes, catalyst.
