Synthesis preparation method: 
1. Directly nitriding metal zirconium with nitrogen at a temperature of 1100-1200 ℃. 
2. Adopt zirconium tetrachloride method. Zirconium nitride was prepared using zirconium tetrachloride and ammonia as raw materials, and the reaction equation is as follows. Zirconium tetrachloride first forms an adduct with ammonia, which is then heated to 750 ℃ to convert into zirconium nitride (Zr3N4), and further heated to 1200 ℃ to convert into zirconium nitride (ZrN). Zirconium nitride can also be prepared by reacting zirconium tetrachloride with ammonia in the presence of hydrogen at temperatures above 1000 ℃. 
Zirconium nitride applications: 
1) Zirconium nitride has excellent neutron properties, thermophysical properties, and chemical stability under high temperature environments, 
It has a high melting point and is one of the material selection requirements for the fourth generation nuclear fission system IMF. 
(Zr-N) compounds have various crystal structures with changes in composition. For example, in the Zr-N alloy system, alloy compounds such as ZrN, o-Zr∝ N ₄, and c-Zr∝ N ₄ have been discovered. They not only have excellent chemical properties, but can also be used in Josephson junctions, diffusion stacks, low temperature sensors, etc., as well as in three-dimensional integrated coils and metal based transistors. At the same time, these Zr-N compounds are superior to pure zirconium in terms of wear resistance, oxidation resistance, and corrosion resistance, and have a higher superconducting critical temperature, making them potentially excellent superconductors with high practical value.   
2) Zirconium nitride is mainly used as a protective layer alloy material for atomic energy industrial reactors, high-temperature resistant alloy material for injection ports of aerospace rocket engines, alloy material for artillery missiles, and corrosion-resistant material for the production of petrochemical reducing chloride reactors or containers. It is also widely used in industrial fields, such as anti-corrosion and decorative layers for automotive accessories, communication devices such as mobile phones, and digital products such as cameras, as well as diffusion barriers for circuit devices. 
3) Zirconium nitride is mainly used in other fields, such as as as an electrical contact layer in the electronics industry due to its excellent electrical conductivity, and as a composite layer in tribology due to its low friction coefficient and good sliding performance. 
4) Used for preparing metal zirconium and zirconia. It is also used to manufacture hot pressed crucibles, refine metals such as aluminum, bismuth, cadmium, lead, tin, and as acid storage containers.
