The chemical formula of zirconium nitride is ZrN. Zirconium nitride has excellent corrosion resistance, high hardness, good lubricity, and ductility. These characteristics also make it an attractive coating. Such coatings are deposited by methods such as physical vapor deposition, in the form of yellow crystalline powder or attractive light golden coatings. Zirconium nitride is widely used due to its properties.

Characteristics of zirconium nitride compounds
The zirconium nitride compound has a variety of crystal structures with the change of composition. For example, in the Zr-N alloy system, the alloy compounds that have been discovered are ZrN, o-Zr₃N₄, and c-Zr₃N₄. Not only do they have excellent chemical properties, they can be used not only in Josephson junctions, diffusion stacks, low-temperature gauges, etc. but also in three-dimensional integrated electrical 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.
Application areas of zirconium nitride
Zirconium nitride powder is widely used in hardware, building materials, toilets, and other daily hardware workpieces. It has been widely used in architectural decoration, household appliances, clocks and watches, jewelry, mobile phones, and other fields, so it has become a highly evaluated research object. Decorative coating industry.
1. ZrN powder is used as nanocomposite hard tools and hard alloys;
