This is a compound of metal and nitrogen with the molecular formula Li3N. It’s a purple/red crystalline solid that has a light-green luster when reflected and a ruby hue in transmitted sunlight.
Property of Lithium Nitride –
Metallic lithium at room temperature can partly produce lithium nitride if it’s exposed to air. In a nitrogen stream that is 15-20 times more efficient than the air, lithium can produce lithium nitride. This is when all of the lithium becomes lithium nitride. It is much more difficult to create nitrides from other alkali elements than this. The only way to prepare sodium nitride is by depositing it on sapphire using an atomic beam at low temperatures. After a few heating, the substance will begin decomposing.
The liquid lithium nitride can be easily dispersed to make lithium hydroxide or ammonia, and especially finely powdered, it can ignite when heated up in the air. It is important to keep lithium nitride in an inert environment (such as nitrogen).
Lithium Nitride Application:
The solidified form of the electrolyte
Lithium Nitride is a high-ion conductor, and it is more conductive than inorganic lithium salts. Numerous studies have shown that lithium nitride can be used as an electrode or cathode for batteries.
Prepare cubic boron-nitride
Apart from being an electrolyte solid, lithium nitride also acts as a catalyst for the transformation of hexagonal to cubic-boron nutride.
An electron-injection layer for an organic light emitting device
OLEDs have the following advantages: full solid state, active emission, large viewing angle, quick response speed (1ms), high operating temperatures, flexible substrate fabrication, low power consumption, and low unit power usage. Lithium Nitride (Li3N), an n type dopant that can be used in the electron transport material Tris (8-hydroxyquinoline) Aluminium (Alq3) to increase the OLED’s efficiency, is used.
