Overview of Lithium Nitride Li3N powder:
Lithium Nitride is a metal nitrogen compound with the molecular formula Li3N. It is the only stable alkali metal nitride. It is a purple or red crystalline solid with a high melting point, a light green luster in reflected light,and a ruby color in transmitted light.Prolonged exposure to the air will eventually produce lithium carbonate. The chemical properties of basic metal nitrides are extremely limited. Among binary compounds,only lithium nitride is stable and easy to prepare (sodium nitrite and potassium nitride are only prepared under more extreme conditions).
Lithium nitride belongs to the hexagonal crystal system. In the lithium nitride crystal, there is a layer of lithium and nitrogen composed of lithium and nitrogen atoms.Lithium atoms are arranged in graphite crystals like carbon atoms, and nitrogen atoms are located in the center of the hexagon of lithium atoms. There is a lithium layer between the lithium and nitrogen layers.Since the ratio of lithium to nitrogen in the lithium and nitrogen layers is 2:1, that is, Li2N (which does not meet the stoichiometric formula Li3N), there are every two lithium layers between the lithium and nitrogen layers. In the unit cell of lithium nitride, the distance between Li-N is 213 pm, which is close to the sum of the ion radii of lithium ions and nitrogen anions. The distance between each lithium nitrogen layer and the adjacent lithium layer is 194pm,
At room temperature, lithium metal exposed to air can partially form lithium nitride, and lithium in a nitrogen stream forms lithium nitride, which is 10 to 15 times faster than lithium in the air, and then all lithium becomes lithium nitride. On the contrary, it is difficult for other alkali metals to form nitrides. For example, sodium nitrite can only be prepared by depositing atomic beams on sapphire at low temperatures and decomposing under slight heating. Lithium nitride is easily hydrolyzed to produce lithium hydroxide and ammonia, especially fine powdered lithium nitride, which will burn violently when heated in air. Therefore, lithium nitride must be processed in an inert atmosphere (such as nitrogen). It can be used as nitriding agent in organic reaction, reducing agent and nitrogen source in inorganic reaction.
Lithium nitride has been discovered since the end of the 19th century and is easily prepared by combining elements. Research on the reaction between lithium nitride and hydrogen began in the early 20th century. Daft and Miklauz discovered that lithium nitride reacts with hydrogen at 220-250°C to form a substance composed of "Li3NH4". They continued to heat the substance at a higher temperature (>>; 700°C) to produce "Li3NH2" and hydrogen.
Lithium Nitride Li3N powder application:
What are the uses of lithium nitride Li3N powder?
Lithium nitride is prepared by the direct reaction of elemental nitrogen and lithium, usually by burning lithium in pure nitrogen. In laboratories and industry, this method is the most commonly used method for preparing lithium nitride. Alternatively, nitrogen can be injected into liquid sodium dissolved in lithium metal to produce purer lithium nitride. Lithium nitride has many applications.
1. Solid electrolyte
Lithium nitride is a fast ionic conductor, and its conductivity is higher than other inorganic lithium salts. Many studies have been conducted on the use of lithium nitride as solid electrode and cathode materials for batteries.
2. Fast ion conductor
A series of lithium fast ion conductors were prepared based on lithium nitride. As a fast ion conductor material, it should have higher decomposition voltage, lower electronic conductivity, higher ion conductivity and better chemical stability.
3. Preparation of Boron Nitride from Lithium Nitride
Lithium nitride (Lin3) is a catalyst for the synthesis of (boron nitride) CBN under high temperature and high pressure. Lithium nitride catalyzes the conversion of Bn to CBN and the reaction of B4C and NH4A at atmospheric pressure and high temperature. It can also be used as a nitrogen source for solvothermal reaction with Bbr3 to generate Bn and CBn. In addition to being used as a solid electrolyte, lithium nitride is an effective catalyst that can convert hexagonal boron nitride into cubic boron nitride.
4. Preparation of lithium difluorosulfinate salt by using lithium nitride.
Lithium difluorosulfimide (LIN(SO2F)2, hereinafter referred to as LIFSI) is an electrolyte with broad application prospects. LiFSI has suitable electrical conductivity, high thermal stability and electrochemical stability
5. Preparation of cubic boron nitride with lithium nitride
Preparation of lithium boron nitride (Li3BN2). Li3BN2 is an important catalyst for the synthesis of cubic boron nitride superhard materials, and has been used in the industrial production of cubic boron nitride synthesis. The hardness of cubic boron nitride is lower than that of diamond, but diamond cannot be used to grind ferrous metals, so cubic boron nitride is currently the best grinding material for ferrous metals and their alloys.
