What’s lithium nitride?
This is a compound of metal and nitrogen with the molecular formula Li3N. It’s a purple or red-colored crystalline solid that has a light green color under reflected and a ruby hue in the transmitted light. The lithium carbonate can be formed over long-term air exposure. It is difficult to understand the chemistry behind basic metal nitrides. Of all the binary compounds available, lithium nitride has the best stability and is easy to prepare.
Metallic lithium at room temperature can partly produce lithium nitride if it’s exposed to the atmosphere. 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 nitrite is by heating it slightly and deposition on sapphire using the atomic beam. It is easy to hyrolyze lithium nitride and make ammonia gases. It is important to keep lithium nitride in an inert environment (like nitrogen).
Preparation for Lithium-Nitride
You can make lithium nitride by reacting directly elemental nitrogen with lithium. It’s usually prepared by burning pure nitrogen and elemental nitrogen to make it. This is the most efficient way to produce lithium nitride in the laboratory and industry. The most commonly used method. You can also pass nitrogen through liquid sodium dissolving with metallic lithium. This produces lithium nitride that is higher in purity.
Application for Lithium Nitride
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 is part of an organic light emitting device
Lithium Nitride (Li3N), a dopant that can be added to the Alq3 Layer of electron transport material, is used in order to increase the OLED devices’ performance. Literature has shown that Li3N is a buffer layer which acts between the electron injection layer (cathode) and the cathode to increase the performance.
