What is zirconium-nitride (ZrN)?
Zirconium Nitride
It is an inorganic chemical compound that has different crystal structures. The characteristics of this compound allow it to be used in various ways. ZrN is an alloy compound that has been discovered in the ZrN alloy system. Not only do they have excellent chemical characteristics, but they can also be used for junctions, diffusion stacks or cryogenic gauges. These compounds can be used to make metal-based and three-dimensional integrated transistors, as well as in the fabrication of electric coils. These ZrN compounds have superior wear resistance to pure zirconium, as well as corrosion and oxidation resistant. They have also a higher temperature at which they can superconduct, making them very useful superconductors. value.
Zirconium Nitride properties
The resistivity of ZrN at room temperature is 12.0 uO*cm. Its temperature coefficient is 5.6*10-8 O*cm/K. At 10.4 K the superconducting temperature transition occurs. And the relaxed lattice parameters is 0.4575nm. Single-crystal ZrN’s hardness is 22.7+-1.7% GPa. The elastic modulus is 450 GPa. ZrN produced by physical vapor deposit (PVD), has a golden-like color.
Zirconium nitride preparation
By carbothermal Nitridation, zirconium nitride nanopowders are prepared from a mixture of zirconium gel and carbon black.

Zirconium nitride
This material is similar to titanium oxide and cement. This material is also used to make cermets, laboratory crucibles, and refractory materials. Physical vapor deposition is often used as a coating method for medical equipment, industrial components (especially drills), automotive and aeronautical parts, and parts that are subject to high wear or corrosive conditions. In the case of alloying ZrN with Al, an electronic structure is formed from the local octahedral symmetry. This octahedral symmetry distorts the cubic ZrN as the Al content rises, resulting in progressively more complex bonding.
The zirconium-nitride coating is used for burs and drills. These coatings can be deposited using physical vapor deposition. Zirconium Nitride-coated tools can be used for nonferrous metal applications. These include machining aluminum alloys such as brass, copper alloys or titanium.
Also, zirconium nitride is used as an inner lining of hydrogen peroxide fuel tank in rockets or airplanes.
