Lithium Nitride (Li3N)

Product Overview
Lithium nitride (Li3N) is the most thermally stable compound among alkali metal nitrides, featuring a unique crystal structure and excellent electrical conductivity. It is a red or purple crystalline solid at room temperature. With a high melting point and strong alkalinity, it reacts with water to release ammonia and is highly reactive with air, requiring storage and handling in inert gases. Lithium nitride is also a promising hydrogen storage medium, capable of adsorbing hydrogen in hydrogen gas environments.

Key Features

• High Thermal Stability: As the most thermally stable alkali metal nitride, Li3N is suitable for high-temperature applications.
• Unique Crystal Structure: Its crystal structure consists of two layers, providing exceptional ionic conductivity.
• Strong Alkalinity: Li3N exhibits stronger alkalinity than negative hydrogen ions, demonstrating high chemical reactivity.
• High Electrical Conductivity: It is a fast ion conductor, offering superior electrical conductivity compared to other inorganic lithium salts.

Applications

• Catalysts and Reactants: Used in organic synthesis, particularly as a catalyst in the high-temperature, high-pressure synthesis of boron nitride.
• Lithium Salt Preparation: Employed in the preparation of lithium bis(fluorosulfonyl)imide (LiFSI), commonly used in lithium-ion battery electrolytes.
• Hard Material Synthesis: Integral in the synthesis of superhard materials like cubic boron nitride, serving as a key catalyst in boron nitride production.
• Solid Electrolytes: As a fast ion conductor, it is used as a solid electrode and cathode material in batteries.
• OLED Electronic Injection Layers: Utilized in organic light-emitting devices (OLEDs) to enhance efficiency and reduce operating voltage.
