Lithium nitride This metal nitrogen compound has a molecular form of Li3N. It is a red or purple crystalline solid, with a light green luster when reflected and a red color under transmitted light.

Lithium Nitride:

Metallic lithium, when exposed to air in a room temperature environment, can produce lithium nitride. Lithium produces lithium nitride faster in nitrogen than in air. In this moment, all the lithium is converted to lithium-nitride. It is much more difficult for alkali-metals to form nitrides when compared with this property. It is only possible to prepare sodium nitride by deposition of atomic beams on sapphire at low temperature.
The fine powdered form of lithium nitride can be explosively combustible when heated. It is important to handle lithium nitride in a nitrogen-free atmosphere.

Application of Lithium Nitride:

Solid electrolyte
Lithium nitride has a higher conductivity than other inorganic sodium salts. Lithium nitride has been studied extensively as a cathode and solid electrode material for batteries.

Preparation for cubic boron Nitride
Lithium nitride has many uses, including as an electrolyte. It is also a catalyst that converts hexagonal boron-nitride into cubic boron-nitride.

The organic light emitting device with an electron injection layer
Organic Light-Emitting Devices have many advantages, including a full-solid state, active emission, a wide viewing angle (1m), fast response speed, able to be manufactured on flexible substrates, large operating temperatures, and low power consumption. Lithium nitride is incorporated as a n type dopant into the tris (8 hydroxy quinoline ) aluminium (Alq3) layers to improve OLED performance.
