What is zirconium nitride?

Zirconium nitride (ZrN) is an inorganic compound with a variety of crystal structures that vary with composition. Due to its properties, it is used in many ways. For example, in the Zr-N alloy system, the found alloy compounds are ZrN, o-Zr ₃ N ₄ and c-Zr ₃ N ₄. It can also be used for 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, corrosion resistance, etc., and have a higher superconducting critical temperature, so they have the potential to become very good superconductors with 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

The zirconium nitride nanopowder can be prepared by the carbon thermal nitridation process of the powder mixture of zirconium hydroxide gel and carbon black.

 Our zirconium powder (chemical formula ZrN) has high purity, ultra-fine particle size and large specific surface area. High surface activity, used for plasticized ceramics and heat-resistant ceramics.

 Application of Zirconium Nitride in Different Industries Nitriding

Zirconium is a hard ceramic material similar to titanium nitride and a refractory material similar to cement. Therefore, it is used in refractory materials, cermets and laboratory crucibles. When the physical vapor deposition coating process is used for coating, it is often used to coat medical devices, industrial parts (especially drill bits), automotive and aerospace parts, and other parts that are susceptible to high wear and corrosive environments. When alloyed with Al, the electronic structure develops symmetrically from local octahedral bonds of cubic ZrN, distorted with increasing Al content, 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 aluminium alloys, brass, copper alloys and titanium.

Zirconium nitride is also used as the lining of hydrogen peroxide fuel tanks in rockets and aircraft.

Zirconium Nitride Overview

The chemical formula for zirconium nitride is ZrN. Zirconium nitride has excellent corrosion resistance, high hardness, good lubricity and ductility. These properties also make it an attractive coating. Such coatings are deposited using methods such as physical vapor deposition. It comes in the form of a yellow crystalline powder or an attractive pale gold coating. Zirconium nitride (ZrN) is used in a variety of applications due to its properties.

Application of Zirconium Nitride

1. ZrN powder is used as nanocomposite hard tool and cemented carbide;

2. ZrN powder is used as high temperature ceramic conductive material;

3. ZrN powder is used as heat-resistant and wear-resistant material;

4. The ZrN powder used as a dispersion reinforcing material is mainly used in the application direction of daily hardware workpieces such as hardware, building materials, and sanitary ware.
