What is lithium nitride?
This is a metallic nitrogen compound with a molecular structure of Li3N. It is a purple or red crystalline liquid with a light green color in reflected and a ruby-colored in transmitted light. The lithium carbonate will eventually form if exposed to air long-term. The basic metal nitrides are very difficult to chemistry. Of all the binary compounds, lithium nitride has the best stability and is easy to prepare.
At room temperature, metallic lithium can partially produce lithium nitride if it is exposed to the air. In a nitrogen stream, lithium nitride is produced by lithium. It’s about 10-15 times quicker than in the atmosphere. All of the lithium is converted into lithium Nitride at this point. It is much more difficult for other alkali elements to form nitrides than this property. The only way to prepare sodium nitrite is by heating it slightly and deposition on sapphire using the atomic beam at low temperatures. It is easy to hyrolyze lithium nitride to make ammonia and lithium hyroxide. 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 is typically made by burning lithium in pure oxygen. This is the best method to prepare lithium Nitride in the lab or in industry. The most commonly used methods. You can also pass nitrogen into liquid sodium dissolved together with metallic lithium. This produces a lithium nitride that is higher in purity.
Application of Lithium Nitride
Lithium-nitride has a high conductivity and is a good ion conductor. Numerous studies have been conducted on the use of lithium nitride for solid electrodes and cathodes in battery manufacturing.
Cubic boron nitride preparation
Apart from being a solid electrolyte lithium nitride also acts as a catalyst for the conversion hexagonal to cubic boron nutride.
Electron injection layer for the organic light emitting device
Lithium nitride, or Li3N, is used as a dopant in the Alq3 layer. This electron transport material improves the OLED device’s performance. Literature has shown that Li3N can act as a buffer between the electron injection and the cathode layers to increase the device’s performance.
