 Lithium Nitride Li3N: Powder Description

Lithium nitride is a white to pale yellow crystalline powder with high purity, high density, high thermal stability, and good electrical properties.

In terms of physical properties, lithium nitride has a density of 1.85g/cm3, a melting point of 240 ° C, and a boiling point of 2450 ° C. In addition, lithium nitride has a high conductivity and good electrical properties, which can be used to manufacture electronic devices at high temperatures.

In terms of chemical properties, lithium nitride has high chemical stability and does not easy to react with water, oxygen, and other substances. It is a weakly alkaline substance that reacts with acids and releases hydrogen gas. In addition, lithium nitride can also generate nitrides through nitriding reactions, such as silicon nitride, boron nitride, and so on.

Lithium nitride, as a new cathode material for lithium batteries compared with traditional lithium battery cathode materials, lithium nitride has higher energy density and longer life. At the same time, the preparation cost is low, so it has broad application prospects in electric vehicles, energy storage, and other fields.

 How is Lithium Nitride Li3N produced?

Lithium metal reacts with ammonia gas.

The reaction of lithium metal with ammonia gas is a common method to prepare lithium nitride. The reaction needs to be carried out at high temperatures and is generally prepared by a tube furnace or induction furnace. The specific steps are as follows:

The higher-purity lithium metal is placed in a tube furnace or induction furnace and heated until it melts.

Through high-purity ammonia gas, the lithium metal and ammonia gas reaction to produce lithium nitride.

Adjust the ammonia flow rate and temperature, control the reaction speed, and prevent lithium metal from reacting too much with ammonia to produce lithium nitride and hydrogen.

After the reaction, the product is taken out, cooled, and crushed to obtain lithium nitride products.

The advantage of this method is that the prepared lithium nitride has high purity and fine particle size, which is suitable for the field with high purity and particle size requirements. However, this method requires the use of high-purity lithium metal and ammonia gas, the production cost is high, and the need to use high-temperature equipment and the equipment requirements are high.

Second, silicon carbide and ammonia reaction

The reaction of silicon carbide with ammonia is also a common method for the preparation of lithium nitride. The reaction needs to be carried out at high temperatures and is generally prepared by a tube furnace or high-temperature furnace. The specific steps are as follows:

The purity of silicon carbide in the tube furnace or high-temperature furnace, heating to a certain temperature.

Through high-purity ammonia gas, the silicon carbide and ammonia gas reaction to produce lithium nitride.

Adjust the ammonia flow rate and temperature, control the reaction speed, and prevent silicon carbide from reacting too much with ammonia to produce lithium nitride and hydrogen.

After the reaction, the product is taken out, cooled, and crushed to obtain lithium nitride products.

The advantages of this method are that the prepared lithium nitride has a high-purity fine particle size, silicon carbide is cheaper than lithium metal, and the cost is lower. However, this method requires the use of high-temperature equipment, higher requirements for equipment, and the reaction speed is slow.

Third, the heating reduction method

Thermal reduction is a commonly used method to prepare lithium nitride. The method is to pass nitrogen and excess ammonia gas into the graphite tube and heat it to 700~1000℃ so that the ammonia gas is reduced to nitrogen atoms and forms nitrogen fossil ink with graphite. The resulting product is then treated at a high temperature (above 1700℃) to remove the unreacted ammonia and graphite and obtain the lithium nitride product. The specific steps are as follows:

Put the graphite tube into the heating device and heat it to 700~1000℃.

Nitrogen and excess ammonia gas are passed into the graphite tube so that ammonia gas is reduced to nitrogen atoms and forms nitrogen fossil ink with graphite.

The obtained product is treated at a high temperature (above 1700℃), unreacted ammonia and graphite are removed, and lithium nitride products are obtained.

The advantages of this method are that the prepared lithium nitride has high purity, fine particle size, and low requirements for equipment. However, this method requires the use of excessive ammonia and requires high-temperature treatment, and the production cost is high.
