What is zirconium nitride?
Zirconium Nitride (ZrN) is an inorganic compound with a variety of crystal structures and changes with composition. It is used in a variety of ways due to its characteristics. For example, in the Zr-N alloy system, alloy compounds that have been discovered are ZrN, o-ZrN, and c-ZrN. They not only have excellent chemical properties, they can be used not only in junctions, diffusion stacks, cryogenic gauges, etc. but also in three-dimensional integrated electric 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, so they may become very good superconductors and have high use. value.
 
Zirconium Nitride properties
The room temperature resistivity of ZrN is 12.0 µΩ·cm, the temperature coefficient of resistivity is 5.6·10-8 Ω·cm/K, the superconducting transition temperature is 10.4 K, and the relaxed lattice parameter is 0.4575 nm. The hardness of single-crystal ZrN is 22.7±1.7 GPa, and the elastic modulus is 450 GPa. ZrN grown by physical vapor deposition (PVD) is a light golden color similar to elemental gold.
 

Zirconium nitride preparation
Zirconium nitride Nanopowders can be prepared by the carbothermal nitridation process of a powder mixture of zirconium hydroxide gel with carbon black.

Our zirconium powder (chemical formula ZrN) is with high purity, ultrafine particle size, bigger surface area. The surface activity is high, uses in the plasticizing ceramics as well as the thermostable organization ceramics.
 
Application of zirconium nitride in different industries
Zirconium nitride is a hard ceramic material similar to titanium nitride and a refractory material similar to cement. Therefore, it is used for refractory materials, cermet, and laboratory crucibles. When the physical vapor deposition coating process is used for coating, it is often used to coat medical equipment, industrial parts (especially drill bits), automotive and aerospace parts, and other parts that are susceptible to high wear and corrosive environments. When alloying with Al, the electronic structure develops from the local octahedral bond symmetry of cubic ZrN, which distorts as the Al content increases, becoming more complex bonding and higher hardness.
Zirconium nitride is used as a hard coating for drills and burs. These coatings are deposited by physical vapor deposition. Zirconium nitride-coated tools are suitable for non-ferrous metal applications, such as the machining of aluminum alloys, brass, copper alloys, and titanium.
Zirconium nitride can also be used as a lining for hydrogen peroxide fuel tanks in rockets and airplanes.
