What is Li3N ( Lithium Nitride )?
What exactly is Li3N? Li3N means lithium nitride. Lithium Nitride is the correct name. Lithium Nitride (metal nitrogen compound) is a red or purple crystalline solid. It has a light-green luster when reflected light is applied and a ruby hue in transmitted lighting. When exposed to ambient temperature, metal lithium can produce lithium nitride at a portion. In addition, lithium can also generate nitrogen nitride 10 to 15% faster in nitrogen streams than it does in the atmosphere. This is when all of the lithium becomes lithium nitride.
Will lithium nitride ignite in the atmosphere? Yes. It reacts with nitrogen in the environment to create lithium nitride. When heated in the air, lithium emits a reddish-tinged glow. The liquid lithium nitride can easily be broken down into ammonia and lithium hydroxide. Fine powdered Lithium Nitride, especially, will burn very quickly when heated. It is important to keep lithium nitride in an inert environment (like nitrogen).
The strong reactivity of lithium nitride, particularly at high temperatures, makes it corrosive to iron, copper and platinum as well as ceramics. Li3N covalent or ionic? Lithium-nitride can corrode iron, nickel, copper and quartz. Lithium is an ionic chemical. 2 is the lithium nitride's charge. Li has an electronegativity 0.98 while nitrogen is 3.04.
History of Lithium Nitride
As early as the late 19th century, lithium nitride had been discovered. This chemical can be made easily by reacting with elements. Zintl and Brauer discovered that lithium nitride crystals had a hexagonal structure. This was first established in 1935. Rabenau, Schultz and single-crystal (X-ray Diffraction) in 1976 redefined this structure.
The early 20th-century saw the first research on lithium nitride's reaction to hydrogen. Miklauz, Dafert, and Miklauz found that lithium nitride and hydrogen react at 220-250°C to produce a substance whose composition is "Li3NH4". This substance was then heated again and decomposed into "Li3NH2", at a higher temperature than 700 degrees C. Substance, hydrogen. Ruff and Georges discovered later that Li3NH4 is Li2NH + LIH, while Li3NH2 is LiNH2+ 2 LiH.
Lithium nitride can be used in many areas. A reasonable explanation can be given by the ionic-polarization model for Li3N's catalytic activity at high temperature and atmospheric pressure, and its role as a source of nitrogen in the Solvothermal Method.
Li3N, which is produced when metallic lithium reacts with N2 at 500 at high temperature and pressure, can act as a catalyst for cBN synthesizing at high temperature. This catalyst can catalyze hBN's reaction at both high and low pressure.
Lithium Nitride, a brownish red liquid with a lumpy shape or powder like sand is known. It can be used as an reducing agent. Why is lithium Nitride used?
1. The solidified form of the electrolyte
Lithium Nitride is a rapid ionic conductor and has a higher electrical conductivity than inorganic lithium salts. There have been many studies that focus on lithium nitride's use as an electrode or cathode for batteries.
A fast conductor material should possess a lower decomposition potential, lower electronic conductivity and ionic conductivity as well as better chemical stability. The above-mentioned characteristics of many lithium fast-ion conducting materials can be used to make all-solid-state battery with outstanding performance. It can also be used as an energy source for electronic devices and products, such as calculators and camera flashes.
The construction of large-scale lithium fast ion conductor material energy reactors (electricity storage) was a possibility. The excess electricity that is not being used during peak times in major cities can be charged into electricity storage stations. The grid is supplied with electricity during peak times. Due to the wide range of applications of lithium fast ion conductors people are very interested. Extensive research was done in order to discover better lithium fast ion conductors.
2. 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.
Japanese researchers in 1987 obtained an N type cBN crystal of 2mm particle size. This was achieved by seeding Si under extremely high pressure and high temperature conditions. Next, a Be-doped P -type crystal surfaced on the crystal by secondary high cBN single. Finally, cBN homogenous junction was obtained by cutting, grinding, and washing.
China also has a similar experiment. On a domestic DS029B six-sided, top-press (DS-029B), the experiment was carried out. The experiment was conducted using hBN at a purity level of 99% to examine the influence of catalysts/additives upon the structure of the cBN sample synthesized under high pressure. This used self-made and commercial lithium nitride Li3N, LiH, as well as commercially available 99% purity LiNH2 additive.
These experiments are based on the phase transition method. Lithium nitride can be used as a catalyst. Hexagonal boron nuitride can also serve as a raw material. Cubic boron Nitride is created by adding diverse additives. X-ray diffraction and Raman diffraction technologies can be used. To analyze and characterize experimental products it is possible to determine that each additive has a different effect on the system.
3. Layer for electron injection in organic light-emitting device
Organic Light-Emitting Devices are made from all-solid-state components and emit light in an active way. Industry considers this to be one of the most promising mainstream displays and lighting technology. OLED manufacturing and performance have seen significant improvements through the development of organic semiconductor materials and organic device structure.
In order to enhance the OLED's performance, lithium nitride (Li3N), can be used as an n type dopant in the electron transport medium tris (8-hydroxyquinoline). It has been reported that Li3N is used as an electron injection layer or cathode. A buffer layer can also be added to improve performance. Li3N becomes N2 and Li3N during the process of evaporation. It is only possible to deposit Li on the device. N2 will not affect its performance. Experimental results show that an Alq3 layer enhanced with Li3N may be utilized as an electron injection layer in order to improve OLED's efficiency and decrease the operating voltage.
